4-TCs could also work in multiple with Class 73/1s and Class 74s in a push-pull manner using the EPB control system [3]. If other (incompatible) locomotives were used then the 4-TCs were plain hauled stock.

Although primarily used on Waterloo-Weymouth services 4-TCs and 3-TCs were also used on elsewhere such as London Waterloo to Salisbury and Clapham Junction to Kensington Olympia services. Electrification finally reached Weymouth in 1988 with the service taken over by Class 442s though the 4-TCs remained in service until 1992.
The 3-TCs were augmented to four coach sets in 1974 by adding the missing TFK [4]. The 4-TCs were Class 491 and the 3-TCs Class 492 under TOPS though later on all were reclassified as Class 438 [5].
A number of vehicles have been preserved including two complete 4-TC sets, one of which is owned by London Underground and carried a "faux teak" vinyl livery for operation with preserved locomotives for a time though is now in London Transport red.
