A Driving Van Trailer (DVT), sometimes referred to as Driving Luggage Van (DLV), is a purpose-built railway vehicle that allows the driver to operate a locomotive at the opposite end of a train. Trains operating with a DVT therefore do not require the locomotive to run round to the other end of the train at terminal stations. Unlike many other control cars, DVTs resemble locomotives (specifically, classes 90 and 91) and thus when the train is operating in "push" mode it does not appear to be traveling backwards.
The vehicles have no passenger accommodation due to rules in place at the time of building that prohibited passengers in the leading vehicles of trains that travel at more than 100 mph (161 km/h).On the Inter City 225 (IC225) sets operating on the East Coast Main Line (ECML) the Mark 4 DVTs and locomotives operate in push-pull formation utilizing a Time-Division Multiplexer to send control signals along specially screened cables which run the length of the train.
