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]

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]
