|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 formed, numbered 900. It included five former 4SUB trailers and at each end was a coach from disbanded 2BIL unit 2006. The two 2BIL coaches were modified with shoegear and multiple unit control apparatus removed and the jumpers altered to enable heating to be supplied from the BRCW Type 3 diesel locomotive rostered to haul the set. The motors were removed from the motorcoach 10573 which reduced its weight from 43 tons to 35 tons. Internally the 2BIL seating layout remained unchanged, the MBS (now a TBS) seating 56 second and the DTC seating 24 first and 32 second.|

|The 4SUB vehicles consisted of four wooden/canvas roofed 10 compartment
'augmentation' trailers 10346/49/51/53 which had all run in augmented
units of the 4326 - 4354 batch, taken from units 4329/46/28/52 respectively,
these units having been withdrawn in 1960/1. These withdrawals had their
'augmentation' trailers removed whilst the three old SUB vehicles were
stripped and sent to the Newhaven bonfires. The withdrawn
'augmentation' trailers were all stored for possible future use, the
four selected for use in Set 900 were some of the lucky few as nearly all the
others were also eventually scrapped at Newhaven without seeing any further
service. These four were initially stored together on the spur line from
Winchester Junction to the Didcot, Newbury and Southampton line, later moving
to Fullerton Goods Yard and then to Micheldever. They were all then taken to
Eastleigh for overhaul where all four were fitted with fibreglass doors before
being formed into Set 900.
The remaining ex SUB trailer used was an all-steel 9 compartment 'psuedo-composite' 11485 removed from unit 4115 from July 1963. This coach was fitted with a lighting generator and became the only 4SUB composite to actually run with first class accommodation, with the centremost six compartments fitted out as first class with four seats across. Three second class compartments remained, two at one end, one at the other. In this form the coach seated 48 first and 36 second. Overall therefore, Set 900 seated 72 first and 604 second and was 448' 10½" long and weighed 206 tons. The ex SUB Composite coach was the centre vehicle of the train with the single second class compartment marshalled towards the former DTC of the 2BIL. The unit was finished in multiple unit green of the later darker shade. Both coaches of the former 2BIL retained their lavatories and, apart from the jumper alterations, the cab ends remained unchanged.
The unit was released from Eastleigh Works 6 September 1963 and entered service the following day. Set 900 was reclassified as a '7TC' unit and numbered 701 from February 1966, though this was somewhat misleading as TC was meant to signify 'Trailer Control' and this set never had this capability, always being used as a conventional hauled train.
701 was overhauled at Eastleigh in mid-1967 and repainted into blue livery with full yellow ends. The cab appearance was also much changed as the former headcode frames were removed and plated over. However, the unit suffered two electrical fires in September 1967 affecting the heating and control equipment and it was not used again in passenger service after December 1967, being condemned 12 April 1969 and stored at Micheldever. The two BIL coaches were sent for scrap to A King Ltd of Wymondham in February 1970. All the ex-SUB coaches, however, were re-used in other units, 11485 being reconverted to second class and modified as an 'EPB' trailer and renumbered as 15084 for unit 5115 (crash damaged at Norwood Junction).
10346 went to 'new' 4SUB 4131 from June 1969.
10349 & 10351 both went to 'new' 4SUB 4132 from August 1969.
10353 went to all-steel SUB unit 4364 (crash damaged at Hampton Court).
