A Driving Van Trailer (DVT) is a purpose-built control car railway vehicle that allows the driver to operate with a locomotive in push-pull formation from the opposite end of a train. Trains operating with a DVT consequently do not need the locomotive to be moved around to the other end of the train at terminal stations. When a train is operated by a DVT, the control signals are encoded and multiplexed onto the cables by the TDM equipment in the DVT. At the locomotive, these signals are demultiplexed by the TDM equipment, and the signals are used to control the locomotive.
