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
Diesel locomotive locomotives. For years, it was thought by American government scientists who measure air pollution that diesel locomotive engines were relatively clean and emitted far less health-threatening emissions than those of diesel trucks or other vehicles; however, the scientists discovered that because they used faulty estimates of the amount of fuel consumed by diesel locomotives, they grossly understated the amount of pollution generated annually (In Europe, where most major railways have been electrified, there is less concern). After revising their calculations, they concluded that the annual emissions of nitrogen oxide, a major ingredient in smog and acid rain, and soot would
