I think the old D-STOCK Trains converted into Class 230 and 484 should be introduced Class 230 for LNWR and TFW Class 484 SWR (Island Line) 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. The British Rail Class 484 is a class of electric multiple unit which is to be built by rolling stock manufacturer Vivarail for the Island Line on the Isle of Wight. The units will be converted from London Underground D78 Stock, originally manufactured in the late 1970s and early 1980s by Metro-Cammell.
