The unique 8-Vab unit 1968-1974
by Tanya Jackson
In March 1968 a unique eight car unit - 8001 (class 480) - was put together from 4-Vep units 7739, 7741 and 7742 to make up for a shortage in stock on the newly electrified Bournemouth line, partly resulting from teething troubles experienced with the motors of the new 4-Rep units. The Vep vehicles that went to form it were brand new and never saw service as Veps before they were formed into the Vab.
The unit was formed:
driving trailer composite (DTC)
non driving motor open brake second (MBSO)
driving trailer composite (DTC)
PLUS
driving trailer composite (DTC)
non driving motor open brake second (MBSO)
trailer buffet (TRB)
non driving motor open brake second (MBSO)
driving trailer composite (DTC)
and was basically two units, one of three cars and one of five, permanently coupled together. The buffet was a loco-hauled carriage specially converted to work within the unit. MBSO 62203, one of those formed adjacent to buffet car has its 3+2 seating converted to 2+1 with tables at the majority of seating bays. The unit was intended to power an additional 4 TC unit, hence the application for 6 motor bogies in the unit, but it also worked singly when it could be counted upon to provide lively running. It was disbanded in December 1974 when a second batch of 4 Reps were introduced.
