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 operate efficiently within a limited torque range, and while low power gasoline engines can be coupled to a mechanical transmission, the more powerful diesel engines required the development of new forms of transmission. The first successful diesel engines used diesel–electric transmissions, and by 1925 a small number of diesel locomotives of were in service in the United States. In 1930, Armstrong Whitworth of the United Kingdom delivered two locomotives using Sulzer-designed engines to Buenos Aires Great Southern Railway of Argentina. In 1933, diesel-electric technology developed by Maybach was used propel the DRG Class SVT 877, a high speed intercity two-car
