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the ETH jumpers.This was in part to compensate for the loss of the Buffet in TC+REP formations as those units were withdrawn over a period of time for scrapping to give up their traction equipment for the new Mk3 based Wessex Electrics.At the time that the Clapham Junction -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

The flexibility of the 4-TC concept is illustrated here, as 73119 'Kentish Mercury' is providing the power whilst coupled to a 4-TC at each end.
