4 SUB Electric Multiple Units
(built on New and Recovered Underframes)

Unit nos.4101–4130, 4355–4387, 4277–4299, 4601–4607, 4617-4620 & 4621–4754

The Southern Railway’s existing suburban electric multiple unit fleet was made up of three-car motor units and two-coach trailer sets. To replace these, a ten-year program was drawn up to be implemented from 1939 for a new ‘second generation’ suburban fleet formed of four-car motor units; later known as the 4 SUB units (4-car SUBurban). The plan envisaged the construction of thirty new ‘all-steel’ vehicles in three batches of ten four-car multiple units and fifty-five trailer cars; the latter would be used to augment the electric 3-Car Motor Units built new about fifteen years earlier.

One hundred and twenty-five trailer sets would be withdrawn, one car of each of these sets being on a standard SR 62' 0" underframe, these underframes would be salvaged and used under later vehicles to be built. Later stages would include a further twenty-three completely new units and one hundred and seventy-nine trailers to augment the remaining three-car sets and finally further ‘new’ units would be constructed on underframes recovered from scrapped vehicles.

The final stage saw the withdrawal of the augmented three-car sets, the original vehicles for scrapping, and the ‘all-steel’ trailer to be used with further new motorcoaches to create further completely ‘new’ units. This plan had the advantages of getting large numbers of new trailers into service quickly without the need for new traction equipment. However, the effects of the second world war and later material and staff shortages saw it somewhat modified.

All units were built at Eastleigh, those on new SR standard 62' 0" underframes having these fabricated at Lancing. Each unit was close-coupled within, using the standard suburban centre-buffer and three-link chain arrangement: this being bolted with shackles underneath the headstock (keeping the centre-buffer under compression). One corridor trailer had a centre buffer at both ends; the other trailer had a buffer at the one end with a rubbing plate at the other whilst both motorcoaches had rubbing plates.

On cab ends there was the usual central drawhook with side buffers, these being self-contained Spencer-Moulton ‘mainline-style’ buffers (as first used on the 6 PUL units). Besides lighting and control jumpers, there was also a 750v (line voltage) power jumper between units.

All the 4 SUB units could run in multiple with the 2 BIL /2 HAL /2 NOL /2 SL /2 WIM /3-Car Motor Units & 4 LAV units (up to twelve cars) but not with the 4 COR (etc) /5 BEL /6 CITY /6 PAN /6 PUL compatible range of units.

Prototype Units Nos.4101 – 4110
(‘Shebas’)

The prototype ‘second generation’ suburban unit appeared in September 1941. It was a four-car all‑compartment unit built at Eastleigh works on Lancing underframes to a new style with much welding and curved bodysides so that each compartment could seat six‑a‑side. The unit was numbered 4101 and comprised two 9-compartment motor brake thirds seating one-hundred & eight, a trailer third with 11- compartments seating one-hundred & thirty-two and a trailer composite with six first-class compartments flanked by two third-class at each end and seating sixty first and forty-eight third, giving a unit total of sixty first and three-hundred & ninety-six third. The unit was 257' 5" long and weighed 144 tons (motorcoaches 43 tons, trailers 29 tons) and painted in malachite green livery.

The motorman’s cab was entered by inwards opening doors, then followed the guard’s brake-van with a pair of outward opening doors on each side. The cab was 4’ 8¼” in depth, whilst the guard’s compartment was 7’ 5½” wide and there was a swing door on the offside into the cab. Then followed nine full compartments each seating 12 and 5’ 6” in width. The motorcoach was to diagram no.2118 and was equipped with EE electrical gear, DH25 compressors and EE339 motors, the motor bogies being of the ‘Central’ type. The compartments at the end of the motorcoaches adjacent to the guard's compartment were designated for ‘Ladies Only’.

The 11-compartment trailer third was to diagram no.2012, each compartment being 5’ 6¾” in width and the 10-compartment trailer composite was to diagram no.2312, with third-class compartments again 5’ 6¾” wide whilst the first-class compartments were 6’ 6” wide.

First-class was subsequently discontinued in suburban trains and with the abolition of Second-class on 3^rd June 1956, Third-class was renamed Second-class. The composite car was thus altered to seat one-hundred & twenty before unit no.4101 entered service and the unit total was four-hundred & sixty-eight third. Trailer bogies were the SR standard 9’ 0” wheelbase bogie with oil axleboxes.

This unit (along with the next nine into service) differed from all later 4 SUB units in having the older style timber and canvas roofs and a squarer cab end design similar to the 2 HAL units with which they could run in multiple.

The sides of the cab on this batch were flat; the body then changing shape to the rounded sides of the remainder of the unit.

Nine further sets unit nos.4102 ‑ 4110 were produced between January and April 1945 to an identical design, but being third-class only from the outset seated four-hundred & sixty-eight. Internally the units were finished with plywood interior partitions and panelling covered in medium brown rexine with cream coloured cotton covering on the ceilings. Seating was the fixed bench type. All ten units were to order number HO 1060.

Eastleigh Body Pressings

Units nos.4101 - 4110 were the first produced using new jigs at Eastleigh works, these being used to produce large metal pressings, mostly with a ¼ light window opening at each end, the outer edges of each pressing forming the edges of the adjacent doorways. Smaller pressings incorporating only one ¼ light window were made for each end of the vehicle.

The pressings were curved from gutter to solebar, whilst steel doors to the same profile were fitted; these each having a droplight window above which was a small oval light. The droplights were frameless and mounted on a spring ‘lazy arm’ (allowing then to be opened variable amounts) with a spring ‘lift rail’ along the top of the droplight to control opening and keep the window closed by latching into clips at the top when required.

Vehicle ends were also formed of large metal pressings, these having some vertical ribbing to give added strength. As this batch still had timber and canvas roofs, they had their gutters in the conventional position at cantrail level, this was raised higher on later units with steel roofs.

Unit no.4108 approaches Manor Road Level Crossing (North Sheen) on a Hounslow Loop to Waterloo service (headcode 89).

This unit carries the BR carriage roundels on its motorcoaches and air-horns, so the photograph dates from after its 13^th June 1963 repaint but prior to Lancing painting yellow panels on units from October 1963. This unit received its yellow panels on 28^th February 1966 with its next varnish at Selhurst.

Into Service

When new, unit no.4101 was put into service on the Victoria to Orpington route which at that time was one of the railways busiest. It was joined from April 1942 by the first ‘augmented’ unit no.4131 to make an eight-car train. However, these units worked throughout the suburban system with unit no.4109 being first used on the South Western lines in January 1946, mostly on the Guildford via Cobham route.

During their first overhauls the rexine was replaced by dark brown or maroon and the cotton ceilings painted custard with toffee brown fittings. With third-class being re-designated as second-class from 3^rd June 1956 the cars were reclassified from MBT to MBS and TT to TS respectively.

From November 1962 units began to be fitted with two-tone air horns mounted on the cab roof replacing the whistle, unit no.4101 being done at Lancing and also gained small yellow warning panels on the cab front, unit no.4110 being one of the first SR units so treated in January 1964.

These units all remained in service until early 1972, two being reformed as a result of accident damage. Most received all-blue livery but three units (nos.4104 /4105 & 4109) were withdrawn in the all‑over green which they had carried since new, although all had full yellow ends applied between July 1967 and October 1968.

Unit no.4102 was the last 4 SUB unit to be repainted blue in February 1971. Four units, no.4103 and the three remaining green units (nos.4104 /4105 & 4109) were used for Xmas mails traffic in December 1971 prior to withdrawal. These units received the class number 405/1 under the BR TOPS classification system just prior to withdrawal.

Augmentation Trailers Nos.10346 - 10400

The first fifty-five augmentation trailers to order number HO 1094 were constructed in 1945‑6 and were similar in design to the 10-compartment trailers in units nos.4101 ‑ 4110 though each compartment was the same width at 6' 1" as no First-class accommodation was intended. This resulted in the Third-class compartments being wider than those in the units nos.4101 ‑ 4110 batch. Each compartment seated twelve passengers giving a total of one-hundred & twenty Third (later Second) class seats. All these vehicles were built at Eastleigh on new underframes from Lancing and weighed 28 tons.

Order number HO 1094 was sub-divided into three with HO 1094A for vehicles 10346 ‑ 10375, HO 1094B for 10376 ‑ 10390 and HO 1094C for 10391 ‑ 10400.

Only the last ten built were of all-steel construction, the first forty-five having timber and canvas roofs, the last suburban cars built with this feature with all later 4 SUB vehicles being of the ‘all-steel’ variety. As a result, most of the wooden roofed cars were in fact withdrawn for scrapping when the unit they were included in was withdrawn in the late 1950s. However, a few saw further use - four in the 7 TC unit no.900 (later no.701), one in 4 LAV unit no.2926 and one in wooden-roofed 4 SUB unit no.4108.

The final ten all-steel vehicles all saw further use, four being converted into de-icing trailers, two going into later 4 SUB units and the remainder converted to 4 EPB trailers. These cars were initially used to augment 3-Car Motor Units nos.1285 ‑ 1310 and nos.1496 ‑ 1524 which were renumbered as unit nos.4300 - 4354 respectively. They were built to diagram number 2013. As both batches of units were being augmented at the same time, cars were allocated between the batches when they were completed and not allocated in any sort of number order. Corner armrests were provided in the all-steel sub-batch (but not the first forty-five built with timber and canvas roofs). The all-steel sub-batch also had the higher gutter line, the wooden-roofed ones having a gutter at cantrail level and a curved rainstrip above.

Following withdrawal, most of these augmentation trailers were removed from their pre-war units and stored, mostly at Micheldever with a few on the Didcot, Newbury and Southampton spur line near Winchester Jct. However, most were not used in traffic again and were eventually taken to Newhaven for scrapping, usually in batches of four marshalled between pairs of withdrawn motorcoaches. These were routed via Strawberry Hill where the motorcoaches were electrically stripped, before being hauled to Newhaven.

Many of these vehicles spent some time in store (usually at Micheldever or on the former Didcot, Newbury and Southampton line near Winchester Jct) following the withdrawal of the pre-war units in which they were running, before being taken to Newhaven for scrapping. One feature of this batch (also seen on the following units nos.4111 ‑ 4120 batch of 4 SUB units) were the two-small semi‑circular air vents above the door droplights in place of the usual oval window. As these doors were fully interchangeable with those on all other 4 SUB (and the SR type 4 EPB units) many of them appeared on other vehicles, outliving this batch of cars by many years.

Units Nos.4111 – 4120
(‘Marys’)

A further ten complete units were next constructed at Eastleigh between April and July 1946, all on new underframes from Lancing and numbered 4111 ‑ 4120. These were also ordered as part of order HO 1060 and were the first all-steel units with a revised cab end design which was followed on all subsequent 4 SUB units built (i.e. with straight cab ends without the dome or inset cab doors).

Experience with the earlier unit no.4101 batch led to a revised seating layout, that of the earlier units now being considered as too cramped, with insufficient room for standing passengers in the narrow compartments. As a result, each vehicle in this batch had one less compartment per car, the motorcoaches now having eight (seating ninety-six), one trailer having ten (seating one-hundred & twenty) and the other trailer having nine (seating one-hundred & eight) six of which were wider than usual to allow possible reinstatement of First-class seating (which never took place). These six wider compartments were in the centre of the vehicle with normal width compartments flanking (two at one end /one at the other) with the two narrower compartments being marshalled against the adjacent motorcoach.

Overall seating capacity of this batch of units was four-hundred & twenty third and they were of the standard 4 SUB length of 257' 5". Diagram numbers allocated were: MBT diag. no.2119, 9-compartment TT diag. no.2314 and 10-compartment TT diag. no.2014.

The guard’s brakevan in these units was slightly wider also at 8' 0½" which became standard in all later motorcoaches built. Units were fitted with the ‘Central’ type 43" motor bogies powered by EE339 275hp motors. Motorcoaches weighed 43 tons and trailers 28 tons giving a unit total of 142 tons.

Internally the units were fitted out similarly to the unit no.4101 batch and this batch were the first to have the much higher gutter line on the car exterior with nothing along the traditional cantrail area. Subsequent to this, units nos.4112 /4115 /4118 were fitted with rainstrips in the traditional position along the cantrail.

Units were close-coupled within, using the standard suburban centre-buffer and three-link chain arrangement: this being bolted with shackles underneath the headstock (keeping the centre-buffer under compression). On cab ends there was the usual central drawhook with side buffers. The corridor trailer had a centre buffer at both ends; the non-corridor trailer had a buffer at the third-class end and a rubbing plate at the first-class end whilst both motorcoaches had rubbing plates.

During first overhaul unit no.4120 had internal partitions replaced by Formica, ceilings replaced by plastic sheet and other panels replaced by ‘Hardec’, a plastic-coated plywood system.

From January 1964 units gained small yellow warning panels on cab ends, unit no.4117 being one of the first units so adorned. Unit no.4117 was painted blue with small yellow panels in October 1966, whilst units nos.4111 /4112 /4113 /4114 /4115 /4116 /4118 & 4119 gained full yellow ends whilst still green and unit no.4120 went straight from green to blue with full yellow ends in July 1967.

Unit nos.4115 & 4118 were withdrawn still in green livery after use on Xmas mails traffic in December 1971, all other units eventually being painted blue with full yellow ends. These units were also classified as Class 405/1 under the BR TOPS classification system from 1972. These units remained in service until withdrawals started in 1972 and all had gone by the end of 1975.

Semi - Saloon Units
Nos.4121 - 4130

The final batch of ten units in the original 1939 order for thirty appeared in service between August / October 1946, and were built at Eastleigh works on new underframes from Lancing and were numbered 4121 ‑ 4130. This batch of units was also ordered as part of order number HO 1060 and became known as the ‘Semi‑Saloon’ units.

These units outwardly appeared identical to units nos.4111 ‑ 4120 and were to the now standard 4 SUB length of 257' 5" and weighed 142 tons as previously with the exception of no.4130 (see later). However, in a further attempt to improve the lot of standing passengers in peak hours, these units had an experimental internal seating layout. One trailer (the 9-compartment pseudo-composite) was identical to those in the no.4111 batch with one-hundred & eight seats all in compartments. The other trailer was of the saloon layout with two internal partitions dividing the car into saloons of three /four /three seating bays.

At the saloon ends were the usual full-width bench type seats for six, but within the saloon the seats were arranged with three to one side and two to the other of an off-centre central gangway. These seats had hammock slung cushions and unlike later saloon cars, the seating units did not have an armrest by the central gangway; this car seated one-hundred & six. The motorcoaches were similar in concept, with one central partition dividing the car into two bays of four, each car now seating eighty-four. Overall unit capacity was therefore three-hundred & eighty-two.

Luggage racks above the seats in saloons were made from welded steel tube which became standard on all later units, though unit no.4130 was fitted with wrought brass racks as fitted to the COR /BUF /RES units. Unit no.4126 had experimental grab handles fitted by the doors in compartment ‘D’ of the compartment trailer. The offside gangway was to the nearside in each motorcoach when that vehicle was leading, that in the saloon trailer was to the same side as that of the adjacent motorcoach. The 9-compartment trailer was marshalled with the two narrower compartments against the adjacent motorcoach.

The final unit of the batch (no.4130) was equipped with experimental EE507 motors, which were lighter in weight at 1.92 tons compared with the 3.6 tons of the earlier EE339 type. In unit no.4130 these were rated at 185hp although the many fitted into later units were rated at 250hp. These motors reduced the weight of the motorcoaches of unit no.4130 to 40 tons and the overall unit weight to 136 tons. These motors were subsequently replaced by EE339 ones in December 1955 and the unit reverted to the standard weight for this batch.

Interior decor was similar to the earlier batches and during first overhaul units nos.4121 /4122 /4123 /4125 & 4128 were retrimmed similarly to the no.4111 batch, units nos.4124 /4126 & 4127 being done in the same style as no.4120. Units nos.4126 ‑ 4129 were given Formica partitions whilst retaining the rexine covered panelling, unit no.4129 also later gained cantrail rainstrips.

Units nos.4121 /4124 /4126 & 4127 were painted all-over blue with small yellow warning panels at Eastleigh during ‘C1’ overhauls during 1966, nos.4122 /4123 /4125 & 4128 gaining full-yellow ends with green livery at Selhurst during ‘C6‘ overhauls in 1967-1968, whilst nos.4129 /4130 went from green straight to blue with full yellow ends (unit no.4130 being the first into this state in December 1967). All units eventually gained this livery on subsequent repaint.

This batch of units started to be withdrawn in 1971 but many of the motorcoaches were converted for departmental use in ‘new’ de-icing units converted at Selhurst between 1977 and 1982. These units were also Class 405/1 under the BR TOPS classification system from 1972.

Augmentation Trailers
Nos.10230 - 10345

Following the construction of the semi‑saloon units nos.4121 ‑ 4130, Eastleigh works then turned out one hundred and sixteen 10-compartment augmentation trailers on new underframes from Lancing between October 1946 and June 1947; identical to those built earlier but all of the all-steel variety. These cars were numbered 10230 - 10345 to order number HO 3351 and all went into pre-war 3-Car Motor Units from various different batches which were then renumbered into the number range 4401 ‑ 4516. Many of these units were withdrawn for modifications and there were numerous exchanges of augmentation trailers between units.

These trailers were inserted into the 3-Car Motor Units at Selhurst, arriving there in batches of four or six (not in numerical order). However, after the first thirty-six had been delivered (with thirty used in augmented units) problems were found with wheels fouling part of the underframe under crush‑loading conditions, so the six unused vehicles were returned to Eastleigh for modification and all subsequent deliveries were already modified. The first thirty were then removed from their units and replaced by modified cars, returned to Eastleigh for modification and subsequently re‑used in later augmentations.

The augmented units began to be withdrawn in the early fifties and all these augmentation trailers were then reformed into new 4 SUB units or fitted with electro-pneumatic (EP) braking and renumbered into the 150xx series and reformed into new 4 EPB units.

The list below shows the number of the pre-war unit(s) in which the car ran as an augmentation trailer, the date of this unit’s withdrawal followed by the number of the 4 SUB or 4 EPB unit into which the car was eventually formed, with its new number (if applicable).

Compartment Units Nos.4355 - 4377
(‘Marys’)

Following on from the one‑hundred & sixteen augmentation trailers built up to June 1947, the next 4 SUB order number HO 3231 was for twenty-three complete units, all on new underframes from Lancing and constructed at Eastleigh to an identical internal layout to units nos.4111‑4120 as units 4121-4130 were still regarded as experimental at this stage and further evaluation of their interior layout was needed before producing more units of this type. Therefore units nos.4355‑4377 should have consisted of two 8-compartment motorcoaches, a 10-compartment trailer and a 9-compartment ‘pseudo-composite’ trailer.

However, a severe shortage of electrical equipment at this time saw these plans badly disrupted. Trailers for these units were completed following the 10230‑10345 batch of augmentation trailers during the summer of 1947, and a further batch of sixty-three augmentation trailers followed from January to July 1948. The motorcoaches were built between September 1947 and June 1948 and many had to be stored at Micheldever waiting fitment of traction equipment.

As a result, planned unit formations were not adhered to, and fourteen of the 10-compartment trailers and nine of the 9-compartment trailers were used for augmentation purposes, being replaced by cars from the following batch of sixty-three, numbered 10167‑10229. This batch of units eventually entered service in reverse numerical order starting with unit no.4377 in September 1947 and ending with unit no.4355 in July 1948.

Due to nine of the ‘pseudo-composite’ trailers being used for augmentation, units 4355 ‑ 4363 had this car replaced by a further 10-compartment vehicle. The first unit to appear, unit no.4377 included another experimental trailer car, an all‑open 10-bay saloon which featured unusual luggage racks with handrails at the gangway sides, also advertisement panels between the luggage rack and the seat back.

This batch of units all had EE339 motors fitted in a ‘Central‘ type motor bogie, and differed slightly in appearance from earlier units in that extra grab rails were fitted on cab ends above and beside the windows, some units having them fitted to both sides, some only on the offside. This was reportedly due to a shortage of brass for the hinges of the opening offside cab observation light so this light was fixed initially on this batch and the grab rails provided to assist staff in coupling /uncoupling operations.

Units were close-coupled within, using the standard suburban centre-buffer and three-link chain arrangement: this being bolted with shackles underneath the headstock (keeping the centre-buffer under compression). On cab ends there was the usual central drawhook with side buffers. The corridor trailer had a centre buffer at both ends; the non-corridor trailer had a buffer at the third-class end and a rubbing plate at the first-class end whilst both motorcoaches had rubbing plates.

One motorcoach on the last unit to appear (unit no.4355) also had experimental roller blind route indicators and the guard’s periscope was fitted with a wiper. If formed as intended, this batch of units should have seated four-hundred & twenty Third (MBT ninety-six, 10C TT one-hundred & twenty, 9C TT one-hundred & eight) and units nos.4364-4376 were in fact so formed.

Unit no.4377 seated four-hundred & two Third due to the inclusion of the all‑open trailer in place of the 10-compt. one and this car only seated one-hundred & two Third. Units nos.4355‑4363 seated four-hundred & thirty-two Third as they included two 10-compt. trailers. Interior trim of these units was as in the unit nos.4101 batch; they differed from the units nos.4111 batch by having hammock slung rather the bench type seating.

During first overhauls, units nos.4355 /4368 /4370‑73 /4376 & 4377 all received brown or maroon rexine panelling with toffee /custard paint whilst the remainder were given Formica partitions, plastic ceilings and ‘Hardec’ panelling. Units were repainted from green (with small yellow warning panels added from January 1964) into all‑over blue with full yellow ends, though quite a few (units nos.4358 /4365 /4367 /4369 /4372 & 4375) received the intermediate version with blue ends and small yellow panels between September 1966 and January 1967.

Units nos.4355 /4357 /4368 /4370 /4371 /4373 /4376 & 4377 gained full yellow ends with green livery, unit no.4360 being disbanded whilst still all‑green and the last of this batch still running in green livery was unit no.4368 (painted blue in March 1971).

This batch of units were among the earlier units to be withdrawn due to the fitment of EE339 motors and the large proportion of compartments and began to be withdrawn in 1972, displaced by SR type 2 HAP units downgraded to second class as 2 SAP and moved to the suburban area. They received the BR TOPS classification Class 405/1 shortly before withdrawal. The remainder (except unit no.4377) were withdrawn in 1973 and 1974 as further BR type 2 HAP units were displaced to the suburban area as 2 SAP by newly delivered 4 VEP units, most being initially stored at Lancing prior to electrical stripping at Selhurst.

Unit formations are as shewn below, with withdrawal date and key letter code for scrap dealer also shown.

Augmentation Trailers
10167 - 10229

The final batch of sixty-three augmentation trailers were built at Eastleigh, on new underframes from Lancing between January and October 1948 and were again 10-Compartment vehicles seating one-hundred & twenty and weighing 28 tons as previously. The first three vehicles were to order number HO 3386, the remainder to order HO 3463.

Twenty-three had to be used to make up the shortfall of trailers in the unit no.4355‑4377 batch (as mentioned above), the remainder went to augment pre-war 3-Car Motor Units as intended which were numbered in the series 4517‑4614 although some numbers were not used and no more than sixty-three units existed at any one time.

Many of these augmented units started to be withdrawn after a relatively short time for their underframes to be recovered for use later in the 4 SUB and 4 EPB construction programme. There were various reforms so that these augmentation trailers often saw service in several pre-war units before all (except two) were converted to EP braking and used in new 4 EPB units. However, two units were used in 4 SUB units nos.4736 & 4748. Details were as follows those cars not used for augmentation being marked with * after car number.

Unit no.4750 is heading for Victoria as 4 SUB no.4683 passes working a Victoria to Epsom Downs (headcode 94) via Crystal Palace train on Wednesday 8^th September 1982. Due to Down platform curvature the guard used to have to walk 15-20’ across the platform to obtain line of sight with the driver for dispatch; many a time he did not make it back on board! The sheer scale of this station is apparent, although not that well looked after by BR back then but very much improved nowadays.

The Standard Units
(‘Marys’)

Following the construction of unit no.4355 in June 1948, came the first of 168 ‘standard’ units built from September 1948 until December 1951. All these units consisted of an eight-bay saloon motorcoach at each end seating eighty-two, one ten-bay saloon trailer seating one-hundred & two and one ten compartment trailer seating one-hundred & twenty. Trailers weighed 26-28 tons (see later), but motorcoaches varied in weight depending on whether fitted with EE339 or EE507 motors at 42 and 39 tons respectively. All units seated three-hundred & eighty-six and were 257' 5" long.

Against the stops at Victoria station platforms 10 & 11 on 8^th September 1980!

No.4721 is equipped with flush roller blind and drop-down pantograph wiper for the motorman. As the 4 SUB units did not have an emergency battery back-up, they were not supposed to display the red roller blinds; hence the obligatory use of oil-tail lamps (here placed by the guard on their platform sides).

In comparison no.4750 retains stencil headcodes and its original sprung-operated side-mounted wiper; these units were not equipped with wipers on their secondman’s observation lights (most of which opened outwards enabling the motorman to change the stencil headcode from within the cab).

Besides the screw-couplings, units had a control jumper (beneath the secondman’s observation light), lighting jumper (below the headcode) and 750v power jumper (under the driver’s observation light). Not visible, but beneath the headstock were the two air-hoses for the Westinghouse braking system.

The first batch to appear were unit nos.4378 ‑ 4387, which were built in two simultaneous batches of five (nos.4378‑4382 & 4383‑4387) between September and November 1948, each batch having slight electrical differences. Units nos.4378 ‑ 4382 were to order number HO 3384 which also included the TTO and MBT vehicles of part of the following batch units nos.4383‑4385 and the TT vehicles for the whole batch of ten units.

Clearly visible are the Spencer-Moulton self-contained buffers of coupled units nos.4651 & 4620 at Ockley & Capel station on Wednesday 7^th April 1982.

Order number HO 3385 completed the remaining vehicles of units nos.4386 & 4387. These units were all on new Lancing underframes and had ‘Central’ type motor bogies with EE339 motors and weighed 142 tons.

The next batch, units nos.4277‑4299 followed between December 1948 and April 1949, again all on new Lancing underframes but fitted with EE507 motors in their ‘Central’ type motor bogies and weighing 136 tons. This batch was to order number HO 3464.

A larger batch of forty-six units nos.4621‑4666 followed from May 1949 through to March 1950, being constructed on underframes recovered from scrapped 3-Car Motor Units of LBSCR origin, though some cars were on new Lancing frames. This batch were ordered as three separate sub-batches, units nos.4621‑4655 being to order number HO 3504, units nos.4656‑4659 to HO 3505 and units nos. 4660‑4666 to HO 3506.

The final eleven units nos.4656‑4666 had slightly different internal fittings (principally in the seat design) but all units had ‘Central’ motor bogies designed for EE507 motors, although most (those up to unit no.4649) entered service fitted with the EE339 variety due to shortages and some were converted to EE507 power later during overhauls. When so equipped, these units weighed 134 tons.

BR code EH 263

The compartment trailers 8901 ‑ 8946 of this batch weighed 27 tons when built on reconditioned underframes and 28 tons if on new ones. Similarly, the saloon trailers weighed 26 tons (reconditioned) and 28 tons (new).

BR code EB 265

Notes on EB 265 Drawing.

1. This contains an error stating ‘automatic drophead buckeye [couplers] outer-ends’.

2. MBS has Central-type motor bogies.

3. Basic Code is shewn as EB 265 2C (although the majority of units were constructed to EB 265 0A) with a variation of EB 265 2D.

Fifteen motorcoaches were next built in April 1950 to order number HO 3618, fourteen of them being used with two 10-compartment augmentation trailers to make up units nos.4601‑4607 which therefore had a non‑standard layout and seated four-hundred & four. These motorcoaches had ‘Central’ motor bogies with EE507 motors and the units weighed 134 tons. The odd motorcoach not used in units no.4601‑4607 went to pre-war augmented unit no.4590 and was later used in 2 HAL unit no.2700 before returning to the 4 SUB fleet in unit no.4282.

BR code EH 266

The final batch of 4 SUB units were built in two distinct lots, units nos.4667-4709 outshopped between May 1950 and December 1950 to order number HO 3617, and units nos.4710-4754 between January 1951 and January 1952 to order number HO 3638 (and this last batch also included the first fifteen 4 EPB units).

BR code EH 265

These units were mostly constructed on underframes salvaged from withdrawn 3-Car Motor Unit vehicles of SECR origin, though again some were on new Lancing underframes. Only one saloon trailer from this batch (8967 in unit no.4687) was on a new underframe and weighed 28 tons, all others weighing 26 tons. All these units included a 10-compartment augmentation trailer removed from withdrawn pre-war units. All had EE507 motors and units nos.4679 /4680 /4681‑83 /4685‑89 /4691‑4753 had ‘Eastern’ type motor bogies distinguished by their shorter ‘kinked’ guard irons, although there was some swapping of motorcoaches in 1959 to ‘tidy up’ this number series to 4681‑89/4691‑4754.

Six units (nos.4688 /4696 /4723 /4728 /4733 & 4739) were non-standard in another way in that they all included one of the ‘pseudo-composite’ 9-compartment trailers (seating one-hundred & eight) originally intended for units nos.4355- 4363 (the remaining three went into 4 EPB units); accordingly, these units seated three-hundred & seventy-four.

Certain units were also fitted with roller blind route indicators, namely units nos.4660, 4694 ‑ 4700, 4718 /4721 and 4736 (one end only). The earlier units nos.4378‑4387 also 4277‑4299 had the extra grab rails on cab ends first seen on the 4355‑4377 batch, but these were missing from the final larger batches of units which (with brass hinges become available following the post-war shortages) had an opening secondman’s observation light which enabled access to the route stencil indicator. Units no.4739‑4754 were delivered in a lighter green livery, becoming standard at first repaint.

Operations

Once all the ‘all-steel’ 4 SUB units were delivered (227 units in total) they could be found operating throughout the suburban system, working in conjunction with augmented pre-war units. All the batches of units were freely intermixed. Units could also be seen working weekend and Bank Holiday relief trains to the coast, mostly on the Central Section routes and a few workings were regularly diagrammed beyond the suburban area on parcels workings. From time to time during stock shortages, 4 SUB units deputised for semi-fast 2 BIL, 2 HAL, 2 NOL and 4 LAV units.

Displacement from the SED

As the 4 EPB construction programme continued from 1951 until 1957, these new units steadily displaced 4 SUB units from the Eastern Section, the newer units being concentrated there as they were required, working in conjunction with the BR type 2 EPB units, for the ‘10-car scheme’.

The 4 SUB units were therefore concentrated on the Central and Western sections, taking the place of withdrawn augmented pre-war units. At the end of the ‘SR’ type EPB construction programme the 4 SUB fleet was allocated roughly 75 Western, 150 Central and 70 Eastern, though these figures included the last 70 augmented units.

These were subsequently replaced by a further 70 ‘BR’ type 4 EPB units, and the 4 SUB units were then rarely seen on the Eastern section, this change was completed by the Summer 1960 timetable, though new 4 EPB units nos.5345–5370 were yet to be built, but there were still some augmented units running to cover the shortfall.

Maintenance

Units were maintained jointly between Wimbledon Park, Selhurst and Slade Green depots for all routine maintenance, some lesser attention was also given at Orpington and Gillingham inspection sheds. Major overhauls and retrimming etc. were dealt with at Lancing Carriage Works, whilst Eastleigh works handled major body repairs after accident damage.

Electrical overhauls were done at Slade Green repair shops and intermediate body overhaul and repainting at Selhurst paint shops. Some unscheduled repairs were carried out in the new Selhurst repair shop from 1957, whilst major overhauls were transferred from Lancing, following closure in 1964, to Eastleigh works.

All 4 SUB vehicles were allocated an electrical code from about 1963.

Units nos.4284 /4288 /4296 /4298 were painted blue with small yellow panels in 1966 at Eastleigh during ‘C1‘ overhauls, most of the others going straight to blue with full yellow ends. Units nos.4277 /4278 /4281 /4299, 4622 /4627 /4634 /4662, 4716 /4718 /4719 /4720 /4721 /4726 /4732 /4737 /4742 /4743 /4744 /4745 /4749 & 4750 received full yellow ends with green livery much later into 1968 at Selhurst during ‘C6’ repaints. Units nos.4720 /4721 /4745 were the last 4 SUB units to run in green livery, being painted blue in January 1971.

With so large a fleet, several units were involved in mishaps leading to unit reformations, sometimes with non‑standard layouts as a result, and a few units were withdrawn prematurely for this reason. Undamaged units started to be withdrawn in numbers in 1972, with those still fitted with EE339 motors being amongst the first to go.

Under the BR TOPS classification system from 1972, units fitted with EE339 motors were allocated the class no. 405/1, those with EE507 motors becoming Class 405/2. Once all EE339 fitted units had been withdrawn, this was simplified for the survivors as Class 405.

Many units remaining in service then exchanged their compartment trailer for a saloon one from withdrawn units reducing the seating capacity to three-hundred & sixty-eight. This process was repeated several times as units were withdrawn until (with one exception) all units remaining in service after 1981 were of the all‑saloon layout.

Later withdrawals had their motors and compressors recovered at Selhurst Repair Shops and their bodies stripped at either Eastleigh for further use in the EPB facelifting programme or at Horwich for similar use, those being sent there were then scrapped on site, those at Eastleigh were sold for breaking-up. The final units were withdrawn from traffic in September 1983.

The following tables show unit formations, with details of previous coach identities for underframes preceded by the number of the last unit within which they operated shewn below where applicable, or unit number from which compartment trailer taken. Completion dates are shown below unit numbers. Reforms to all‑saloon layout are also shown, together with withdrawal date and scrapping details where known. Car designations are shown as MBS, TS etc. the classification from June 1956 when Third class was redesignated as Second. Coaches were actually delivered new as MBT, TT etc.

+	All‑open unit. Shown after the unit number and again against the number of the inserted TSO in the TS column, diagram 2018, code DR unless otherwise shown.
*	Shown against the number of the inserted TS in the TSO column, this unit by then being out of traffic for disposal, though some TSs were converted for use in 4 EPB units and saw further service, diagram 2013, code DN unless otherwise shown.
^¶	Shown following the vehicle number and denotes the body was mounted on an Ashford underframe, all unmarked coaches being on a Lancing underframe.

The ‘Tlr. Exch’ column shows the unit number of the other unit involved in the trailer exchange and the date of this exchange shown below.

Number in brackets after scrap code indicates number of vehicles scrapped where units not sold as 4 coach sets.

Carrying ‘unicycling lions’ and with an augmented 4 SUB on the rear, unit no.4378 enters Clapham Junction’s platform 11 on a Horsham service via Motspur Park (headcode 17).

Units Formed from April 1950
with Two Augmentation Trailers

Illuminated by the sunlight, the partitions in each of the two 10-compartment augmentation trailers are clearly visible in this unidentified unit from the 4601-4607 batch. This Dorking to Victoria working is seen close to Boxhill in April 1967.

Displaying both tail lamp and headcode on its rear, unit no.4678 departs from Upper Sydenham towards London; this was the penultimate station on the Crystal Palace High Level line which closed on 20 September 1954. These units did not have starting bells so relied on dispatch by a guard and his flag. © Chris Wilson collection Standard Units

Individual Unit Notes

Many units were reformed from the mid‑seventies in an attempt to limit the number of compartment trailers remaining in service. Withdrawn units donated their open trailers to one remaining in traffic and were sent for scrapping with two compartment trailers, not running in service in this form. Units remaining in traffic in ‘all‑open’ form (marked with a + against the unit number in the above lists) then seated three-hundred & sixty-eight.

This process continued through various rounds of unit withdrawals, and from the early eighties was amended, a number of units being sent to Horwich works for scrapping with both open and compartment trailers, some of which were converted to all‑open saloon trailers for further 4 EPB units as part of the 4 EPB facelift programme. Interior seating fittings from many vehicles were re‑used, particularly in compartment vehicles stripped‑out to open saloons, before the donor vehicles were scrapped.

Set 900
(later 7TC 701)

When Oxted line services were dieselised in 1963, there was a chronic shortage of electrically heated stock for the diesel locomotives to haul on peak-hour extras so a seven‑coach, high‑capacity electrically‑heated set was authorised to be formed by HO 5278 dated 15-Oct-63, the set having already been formed at Eastleigh on 6^th September numbered 900.

It included five former 4 SUB trailers and at each end was a car from disbanded 2 BIL unit no.2006. The two 2 BIL cars were modified with shoegear removed, multiple unit control apparatus removed and jumpers altered to enable heating to be supplied from the BRCW type 3 diesel locomotives rostered to haul the set.

The motors were removed from the motorcoach 10573 reducing its weight from 43 to 35 tons. Internally, the 2 BIL seating layout remained unchanged, the MBS (now TBS) seating 56 second and the DTC seating 24 first and 32 second. The 4 SUB vehicles consisted of four wooden‑roofed 10- compartment augmentation trailers 10346 /10349 /10351 & 10353 which had all run within augmented units of the no.4326 series from units nos.4329 /4346 /4328 /4352 respectively which had been withdrawn in 1960 /1961 and these trailers went into store at Micheldever.

These vehicles moved to Eastleigh 8-Jul-63 and were overhauled and received fibre-glass doors before being formed into Set 900. The remaining vehicle was an all‑steel 9-compartment pseudo-composite 11485 removed from unit no.4115 during overhaul at Lancing and moved to Eastleigh 14-Aug-63. This car was fitted with a lighting generator and became the only 4 SUB composite to actually run with First-class accommodation, with the centre-most six compartments fitted out as First-class with four seats across. Three Second-class compartments remained, one at one end, two at the other. In this form the car seated fouty-eight first and thirty-six second. 2 BIL unit no.2006 had arrived at Eastleigh 16-Aug-63 for damage repair to DTC 12107.

Overall, Set 900 seated seventy-two first and six-hundred & four second. The 4 SUB composite car was the centre vehicle of the train and the end with the single Second-class compartment was towards the former DTC of the 2 BIL. Set 900 was 448’ 10½” long and weighed 206 tons. It was finished in multiple unit green of the later darker shade; the composite carried the UIC yellow band. Both cars of the former 2 BIL retained their lavatories and (apart from the jumper alterations) the cab ends were unaltered.

The unit was released from Eastleigh works 6^th September 1963 and entered service from 10^th September 1963. Note that the unit was formed and in service before the HO order had been authorised. Set 900 was reclassified as 7TC from February 1966 and renumbered 701.

It was overhauled at Eastleigh between 24^th July 1967 and 8^th September 1967, being repainted blue. The cab end appearance was altered by removal and plating over of the former headcode frames. It went back into traffic by 28^th September 1967.

However, the unit suffered two fires affecting the control equipment in October 1967 undergoing repairs at Selhurst between 4^th November 1967 and 13^th November 1967; it was not used again in passenger service after December 1967, being condemned on 12^th April 1969 and stored at Micheldever. Five cars of the unit were in store at Eastleigh by August 1969, 11485 and 10346 by this time having been removed for use in other units, but both of the former 2 BIL cars were back at Micheldever by December 1969.

The two 2 BIL cars went for scrap to A. King Ltd (Wymondham) moving from Hounslow 26^th March 1970 and all the former 4 SUB cars were re‑used in other units; 11485 being reconverted to Second-class and converted to 4 EPB trailer 15084 for unit no.5115 at Derby in January 1969. 10346 went to ‘new’ 4 SUB unit no.4131 from June 1969, 10349 and 10351 both to ‘new’ 4 SUB unit no.4132 from August 1969, 10353 to unit no.4364 from June 1970 after a period back in store at Micheldever.

The unit formation was as follows:

Unit	TBS	TS	TS	TC	TS	TS	TC
Diag. No	2111	2013	2013	2314	2013	2013	2700
Code	-	DN	DN	DP	DN	DN	-
900 (then 701)	10573 (2006)	10346 (4329)	10349 (4346)	11485 (4115)	10353 (4352)	10351 (4328)	12107 (2006)

With an all-blue 4 VEP behind, unit no.4132 sits in platform 11 at Victoria. This unit was formed in August 1969 (blue livery) using ex.2 HAL motorcoaches sandwiching wooden-roofed augmentation trailers original built to strengthen 3-Car Motor Units (thence to set 900 /7TC set 701). Both units were withdrawn on 9^th October 1971.

Note the oil-lit tail lamp on edge of platform 10.

Hybrid Units 4131 and 4132

Two hybrid 4 SUB units were formed during 1969 numbered 4131 and 4132, unit no.4131 in May and unit no.4132 in August 1969. This was due to an increased requirement for suburban units as a result of timetable changes. Both units were made up of a ‘1939 type’ 2 HAL MBS at each end, flanking two 10-compartment 4 SUB trailers, three of which were wooden‑roofed vehicles from recently disbanded 7 TC unit no.701, the remaining one an all‑steel vehicle taken from damaged unit no.4282.

The ex.2 HAL MBS cars were taken from units nos.2622 /2637 /2659 & 2688 and were unaltered seating seventy second in seven compartments. These cars weighed 44 tons so overall units nos.4131 & 4132 weighed 144 tons and seated three-hundred & eighty, all in compartments. Both units were in given C1 overhauls and painted in all-blue livery with full yellow ends. Unit no.4131 was released from Eastleigh 30^th May 1969 and no.4132 9^th August 1969.

These units had only short lives, both being withdrawn on 9^th October 1971 and scrapped by A. King Ltd (Wymondham) August 1972 after periods of storage at Micheldever, Weymouth and Feltham. Final disposal for scrapping was protracted as the train was delayed en route owing to defects, the units finally moving away from Hounslow 2^nd August 1972.

Unit no.4132 was still extant at Wymondham 10^th September 1972.

Dates below the unit number were ‘paint dates’:

Unit	MBS	TS	TS	MBS

4 SUB Livery Summary

Most units were delivered in Southern Railway (later) Malachite Green livery thence early BR Green from March 1949. Initially under British Railways (following nationalisation on 1^st January 1948) units will have continued to be outshopped in Southern Railway Malachite Green using Southern typeface; the exact date of change of typeface at Lancing is currently uncertain and possibly pre-dates the change to ‘early’ BR Green.

BR Green Liveries

Whilst the Railway Executive published its ten standard liveries in February 1949 there would have been a delay before adoption at various railway depots. Individual unit record cards shew BR Green being used at least by 17^th May 1949 although exactly what shade this ‘early’ BR Green was is not described thereon. Prior to this date units are described as ‘BR Repaint’ until further details emerge as to the change from Malachite to BR Green (the precise difference being unclear although some Lancing Carriage Works notes appear to separately identify the two).

Units overhauled from July 1956 gained a slightly darker ‘Southern Region’ version of this livery. However, a few units new in 1951 (nos.4735 to 4754 plus the first fifteen 4 EPB units) were reported as having a ‘lighter’ green paint compared the early BR green; this being standardised at their first repaint.

Dates preceding the livery code are ‘paint dates’ applied to the vehicles at works. These sometimes varied between cars of a unit (sometimes by a week or so) and the latest one is shown in those cases.

En-route to Alton, unit no.4691 (with a pair of two 2 BILs on the rear) passes through Weybridge station (Down Fast) on an evening peak-hour service in 1960. This was prior to the 1966 extension of the Addlestone bay platform.

Depot Allocations

For the bulk of their lives the 4 SUB units were not allocated to specific depots for their routine maintenance, being shared between all three Southern Divisions and intermixed with the older wooden-bodied units. Diagrams were complex and a few started on the Eastern Section and ended-up berthing on the South Western and vice versa.

Some units were withdrawn before ever being allocated to a depot. Other units were allocated to specific depots from 29^th July 1971 and more from 4^th October 1971 (except for 4 SUB, 4 COR and most 4 EPB units) 4 SUB units being joint between SWD (87 units) and CD (108 units), 4 COR being joint between SWD and CD and 4 EPB units being joint between CD (40 units) and SED (211 units) with 5101 /5102 /5104-5130 to WDON.

This was revised again from May 1972 with all surviving 4 COR at BTON (Brighton) and the closure of Streatham Hill with its allocation moving mostly to BTON (Brighton) and a few to RMGT (Ramsgate).

Units which survived long enough to allocated are shown in the table below with their initial allocation shown as ‘joint’ (shared between Wimbledon Park ‘WDON’ and Selhurst ‘SHST’). Diagrams were revised from 7^th May 1973 allowing units each to be operated on just one of the three divisions; the fleet was then split between Wimbledon Park and Selhurst (with none on the SED).

The ‘multiple-unit’ depot codes subsequently changed as follows with the later codes being used in the table below for consistency.

1st	2nd	Depot
BTON	BI	Brighton
ELGH	EH	Eastleigh
FTON	FR	Fratton
RMGT	RE	Ramsgate
SHST	SU	Selhurst
SLEO	SE	St. Leonards
SLGN	SG	Slade Green
WDON	WD	Wimbledon

Led by another 4 SUB, no.4288 departs from East Croydon
(7^th November 1978).

Slades Green

Slades Green station opened in 1901 and followed the name given in the earliest Ordnance Survey map of the area (1864). However, in 1953 the local Member of Parliament deemed this spelling to be incorrect and took his case to Parliament (a Deed of 1561 spelled ‘Slade Green’). The Southern Region capitulated and both station and depot changed their name to Slade Green on 21^st September 1953.

Unit no.4732 being hauled down the Fast Lines to Eastleigh Works by LT electric locomotive ‘Sarah Siddons’ 27^th May 1983.

4 SUB in Model Form

It is hoped the 4 SUB ‘Mary’ kits will be available again as a kit from No-Nonsense Kits (based on the MTK range). Ajay /Southern Region Models have made 4 SUB resin kits. The Blacksmith ‘Sheba’ kits appear to be no longer available.

Thanks go to research author John Atkinson, webpage author, editorial and additional information from C.Watts along with the many photographers listed below their images; particularly Chris Wilson.
