There the 4TC/s would couple to the waiting 4REP which would then power the whole formation to London, leaving the Class 33/1 locomotive at Bournemouth to await the next such service.

4TC units were occasionally seen on other duties such as Waterloo to Salisbury, the Clapham Junction to Kensington Olympia shuttle before that line was electrified and surplus units were also used on Sundays to operate Portsmouth Harbour to Reading direct services during the late 1970s & early 1980s.

They ventured further afield on special duties or rail-tours, including Birmingham, Cardiff, Barnstaple/Meeth & Meldon Quarry.

Until the closure of the Swanage branch, a small number of through 4TC workings to/from Waterloo were operated, also using class 33/1 locomotives in similar style to the Weymouth trains.

This modified car was then placed into unit 417 from the early 1970s, and the displaced 76302 was kept spare at Bournemouth Traction Maintenance Depot.

A feature of a journey in a 2x4TC/4REP train with the 4REP pushing, was severe jolting at station restarts; this upset many a hot drink over the years.

The Units were fitted with a motor-generator set for lighting supply and a single compressor; these drew power from the REP or loco through the ETH jumpers.

This was in part to compensate for the loss of the Buffet in TC+REP formations as those units were withdrawn over a period of time for scrapping to give up their traction equipment for the new Mk3 based Wessex Electrics.

On occasion, class 33/0 locomotives were substituted for unavailable 33/1s; in this event the loco had to run-round at Weymouth and the starting bell Loudaphone inter-carriage telephone system could not be used, the guard having to resort to the use of a green flag to start the train at station stops.

At the time that the Clapham Junction - Kensington Olympia service was being run by Network South East with Class 73 traction DTSO number 76327 was part equipped with a modernised interior.

The driving end was fitted with 4CEP style windows, ceiling (with fluorescent lights and luggage racks but with 3+2 Class 319 seating.
