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
Steam diesel hybrid locomotive a steam engine offered a high starting torque—a tractive force of was available—while a diesel engine offered a high fuel efficiency and it was considered desirable to combine the two. In outline the machine resembled a conventional 2-6-2T steam locomotive, but it had four pairs of horizontally opposed cylinders (13½ inch bore × 15½ inch stroke—343 × 394 mm) mounted longitudinally above the frame and driving a crankshaft placed between them, with the further drivetrain by gears. The cylinders were made double-ended, with the rod end of each cylinder for steam and the closed end fitted with a diesel injector.
