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
Rigid-framed electric locomotive reluctant single prototype, built for comparison with the articulated 2′B+B1′ , which had themselves been a reaction to the poor performance of the 1912 1′D1′ . A rare example of the 2′D2′ layout was the unique British diesel-mechanical of 1955. Rigid-framed electric locomotive Rigid-framed electric locomotives were some of the first generations of design. When these began the s of these early locomotives, particularly with AC motors, were too large and heavy to be mounted directly to the axles and so were carried on the frame. One of the initial simplest wheel arrangements for a mainline electric locomotive, from around
