caption_attribution_description: English: A Class 230 DEMU at Bedford Midland station.
context_page_description: The British Rail Class 230 D-Train is a diesel electric multiple unit or battery EMU built by rolling stock manufacturer Vivarail for the British rail network. The units are converted from London Underground D78 Stock, originally manufactured during 1980 by Metro-Cammell. The conversion re-uses the D78's aluminium bodyshells with new interiors. It runs on the same bogies but these are rebuilt to as-new standard by Wabtec and fitted with brand new 3-phase AC induction motors sourced from Austria. The initial build of 3 vehicles for London Northwestern Trains replaces the four-rail traction-current system with 4 diesel gen-sets, driving 8 traction motors via purpose built electronic Traction Control Units.
  In this configuration, every wheel is driven and all are braked by a computer-controlled blended reactive/pneumatic braking system, allowing for optimum braking performance in all weather conditions.
  The type has been assigned the designation of Class 230 under TOPS.
  During August 2016, a prototype was produced for testing and accreditation; the type was planned to be prepared to enter passenger service during the following year.

  During August 2016, a prototype was produced for testing and accreditation; the type was planned to be prepared to enter passenger service during the following year. During July 2016, it was announced that the prototype was to be tested in mainline service on the Coventry to Nuneaton Line over a 12-month period with operator London Midland; however, this trial deployment had to be postponed after the prototype was damaged by a fire and could not be repaired quickly enough. It is proposed that up to 75 units may be converted, with each unit consisting of two or three cars. During October 2017, West Midlands Trains announced that it would procure three 2-car D-Trains for the Marston Vale line. and the first unit entered service in April 2019.
