Electro-diesel multiple unit

Summary

(Learn how and when to remove this template message)

An electro-diesel multiple unit (EDMU) or bi-mode multiple unit (BMU) is a form of a multiple unit train 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 alternating current (AC) or direct current (DC) electric power (like a diesel-electric multiple unit – DEMU).[1][2]

List of EDMUs edit

Asia edit

China edit

China Railway CR200J-SG Fuxing high-speed train is a power-concentrated electro-diesel (bi-mode) multiple unit specifically designed for plateau operation. Each train consists of HXD1D-J electric locomotive (power car) at one end, FXN3-J two-unit diesel locomotive (two power cars) at another end, and 9 25-T passenger coaches between them. Electric and diesel power cars have their own independent traction motor systems, but can be operated from cabs of each other. HXD1D-J is a special version of HXD1D electric locomotive manufactured by CRRC Zhuzhou Locomotive and FXN3-J is a special version of a FXN3 locomotive manufactured by CRRC Dalian – both of them have changed body design and are adapted for joint operation as part of a train.[3][4] These trains are served on Sichuan–Tibet railway.[5]

Oceania edit

Australia edit

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.

Europe edit

France edit

 
SNCF B 82500 BMU

Bombardier has built dual-mode variants of its AGC series[6] for the French operator SNCF; the electricity is collected by means of a pantograph.

  • B 81500multiple unit trains using 1.5 kV DC catenary. In service since 2005.
  • B 82500 – multiple unit trains using both 1.5 kV DC and 25 kV AC catenary. In service since October 2007.
  • Alstom Règiolis (B 83500, B 84500, B 85000, B 85900). In service since April 2014 (B 83500 and B 84500).

Italy edit

Netherlands edit

  • 18 bi-mode units of the Stadler WINK have entered service in 2021 with Arriva Netherlands. In addition to electric and diesel propulsion, these trains can also run on battery power.[9]

Norway edit

  • 14 bi-modal variants of the Stadler Flirt trains, called Norske Tog Class 76 [no][10] in Norway, held by the state owned Norske Tog and operated by the line operator SJ AB (as SJ Nord) entering service in 2021.[11] This class is used on the regional train services around Trondheim.

Poland edit

 
EN63H West Pomerian Voivodeship operated by Polregio

Russia edit

  • DT1 (ДТ1) Russian-gauge multiple unit. In service since 2009.

Spain edit

 
Renfe Class 730

Renfe Class 730 – a bi-mode subversion of Renfe Class 130, a dual-gauge, dual-voltage high-speed power-concentrated electric multiple unit, a part of Talgo 250 family. In 2012, 15 original Class 130 trainsets were modified to Class 730 by replacing their end passenger coaches with diesel-generator cars. Each train consists of 13 cars, including 2 electric locomotive-like power cars, 2 diesel-generator cars and 9 passenger coaches.[14] One train crashed in 2013, another 14 are still in use on Alvia services.[15]

United Kingdom edit

 
British Rail Class 802

Electro-diesel multiple units whose electricity source is 25 kV 50 Hz AC overhead line include:

British Rail Class 755 – multiple unit for use on Greater Anglia regional services. In service since July 2019 (755/4).[16][17]

North America edit

 
New Haven #140 "Roger Williams", unique Budd railcar-based train at Danbury Railway Museum, Connecticut

United States edit

The following were retired from New York City service:

  • "Roger Williams" – streamlined 6-car lightweight DMU passenger train, built by Budd Company in 1956 for New York, New Haven and Hartford Railroad; primarily diesel-hydraulic, third-rail electric mode for short-term use only. Three cars preserved.
  • GE/Garrett gas turbine MUs – primarily electric, but built with gas turbines to allow operation outside of third rail electrification. All scrapped.
