Car 5 (DVT) The Driving Van Trailer allows the train to be driven in both directions without having to run the locomotive around. I have removed the original fittings, and added windows and seats to provide extra passenger accomodation. The original imitation motor bogie has been replaced with the short one from the loco. Also, on a vehicle without a motor, no pantograph was needed, so this has been relocated to the locomotive at the other end of the train.
