Electro-diesel multiple unit
An electro-diesel multiple unit (EDMU) or bi-mode multiple unit (BMU) is a form of a multiple unit that can be powered either by electric power picked up from the overhead lines or third rail (like an electric multiple unit – EMU) or by using an onboard diesel engine, driving an electric generator, which produces AC or DC electric power (like a diesel-electric multiple unit – DEMU).[1][2]
List of BMUs
China
Two variants of the China Railway CR200J-SG Fuxing (HXD1D-J and FXN3-J) high-speed train are electro-diesel (bi-mode) multiple units specifically designed for plateau operation. They are HXD1D-J manufactured by CRRC Zhuzhou Locomotive and FXN3-J manufactured by CRRC Dalian. Two variants are served on Sichuan–Tibet railway.[3]
Australia
NSW TrainLink Regional Train Project is building 117 bi-mode carriages (1.5 kV DC) to replace its diesel fleet of interstate and regional XPT, Xplorer and Endeavour trainsets to be delivered by CAF from 2023.
France
Bombardier has built dual-mode variants of its AGC series[4] for the French operator SNCF; the electricity is collected by means of a pantograph.
