A Driving Van Trailer or DVT 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 travelling backwards.

[edit] Development

On the IC225 sets operating on the ECML the Mk4 DVTs and locomotives operate in push-pull formation utilising a Time-Division Multiplexer to send control signals along specially screened cables which run the length of the train.

On the original Mk3 DVTs, which operated on the WCML, the intention was to use the RCH jumpers to carry the signals therefore allowing the same cables to be used for lighting and the public address system, as well as driver-guard signalling. However this proved to be very troublesome in service and eventually the rakes of coaches on WCML were re-wired with specially screened cables exclusively for the TDM system.

In addition to the driver's cab, some DVTs have luggage and cycle storage 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.


MK3 DVTs can be seen in service in the UK today with the EWS Company Train, with 'one' Anglia and occasionally with Virgin West Coast . The new open access operator Wrexham & Shropshire will utilise Mark 3 DVTs on its services between London and Wrexham. Class 67 and Class 90s provide the power to these DVTs. The BR MK4 DVT is operated by National Express East Coast and powered by Class 91s and by the unique Class 89 co-co locomotive which once operated between London Kings Cross and Leeds.

Used to operate push-pull services on WCML between London Euston, Manchester, Birmingham and Glasgow in conjunction with class 86, 87 and 90 locomotives, but now the services are run exclusively by Class 390 Pendolinos. Virgin retained 2 DVTs for backup purposes, both DVTs have recently been fitted with OTMR so it appears their future is more secure with Virgin West Coast.

[edit] One Anglia

Operate push-pull services between London Liverpool Street and Norwich in conjunction with class 90 locomotives. These DVTs were originally used by Virgin West Coast until the Pendolinos were fully operational. All the WCML DVTs needed refurbishing when they came off lease and were re-painted into 'one' colours.

[edit] EWS

EWS operate a Mk.3 DVT as part of their EWS Company Train. 82146 is painted in the Silver colours of the executive train and operates with 67029 and three MK3 coaches.

[edit] Wrexham & Shropshire

Due to start operating push-pull services in Spring 2008 between Wrexham General and London Marylebone in conjunction with Class 67 diesel locomotives. The DVT's require modification to work with the Class 67, involving adding a notched power controller as is used in the locomotive and a 27 wire jumper cable the same as used between all the GM locomotives known as the AAR Multiple Working system. These DVTs were originally used by Virgin West Coast until the Pendolinos were fully operational. The Wrexham & Shropshire DVT's are currently undergoing refurbishment and modification including fitment of OTMR data recorders.

MK4 DVTs were built in 1988 by Metro Cammell at their Washwood Heath plant in Birmingham and were introduced to the ECML with the IC225 rakes of Mk4 coaches. They operate the class 91 locomotives using the TDM system via UIC screened cables through the nine Mk4 coaches of the rake.

Initially operated by BR's InterCity sector in its familiar livery, following privatisation of the railways the services were taken over by Sea Containers under the Great North Eastern Railway (GNER) brand but following a change of operator in December 2007 they are now run by National Express and will in future be re-liveried into 'National Express East Coast' grey and white colours.
