Vectron (locomotive) Vectron (locomotive) The Vectron is a locomotive series made by Siemens Mobility, introduced at the 2010 InnoTrans trade fair in four prototype versions: diesel, multi-system, and both AC and DC electric power. The Vectron series is reconfigurable and modular, with a Bo'Bo' wheel arrangement, and is intended as the successor to the EuroSprinter family of locomotives. Around the end of the 20th century and the beginning of the 21st century Siemens successfully produced freight and passenger/universal versions of its EuroSprinter locomotive platform; initially made as single voltage machines for European state railways (Austria, Germany), later as multivoltage locomotives for cross
Electro-diesel locomotive take advantage of shorter sections of electrified main lines. Bombardier has built dual-mode variants of its AGC series for the French operator SNCF; the electricity is collected by means of a pantograph. In Russia, a number of electro-diesels were built which had both pantographs and diesel prime movers; these locomotives were actually multiple units, with distinct electric, diesel, and motor sections. These included: An experimental electro-diesel locomotive, DEL120, was built by London Underground in 1940 but was not a success. Two types have been built whose electricity source was a 750 V DC third rail. Electro-diesel locomotives and multiple units
