This article is about British DVTs, which are a type of railway control car.
A Driving Van Trailer or DVT is a purpose-built railway vehicle that allows the driver to operate a locomotive from the other end of a train. Trains operating with a DVT therefore do not require the locomotive to run round to the opposite end of the train.

[edit] Development
DVTs and locomotives operate in push-pull formation utilising a Time-Division Multiplexer to send control signals along the "RCH" jumper cables that run the length of the train. This allows the same cables to be used for lighting and the public address system, as well as driver-guard signalling. In addition to the driver's cab, the DVT has luggage space and a guard's office.
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. The air braking system is operated directly from whichever cab the driver is driving from. If the TDM fails and cannot be reconfigured, the train may still operate, but if the DVT is leading, it will be necessary to uncouple the locomotive and attach it to the front of the train.
The British DVT was developed from the DBSO, but unlike its predecessor, it was built specifically for this purpose. The original DVTs were designed to be used with British Rail Mark 2 D, E & F and British Rail Mk 3 coaches, and the second design with British Rail Mk 4 coaches, which have a narrower profile. This enables it to be converted to tilting operation if required in the future.
[edit] United Kingdom
DVTs can be seen in service in the UK with GNER, Virgin Trains and 'one' Anglia. Locomotive types which have been used to provide the power include Class 67 diesel locomotives and Classes 86, 87, 89, 90, and 91 electric locomotives.

[edit] Republic of Ireland
CAF DVTs are being gradually introduced on the intercity service of the Irish Rail network with power being provided by the General Motors 201 Class locomotive.
