The Vectron is a design of reconfigurable, modular Bo′Bo′ multipurpose locomotive by Siemens Mobility, intended to be the successor to the successful EuroSprinter family of locomotives. Diesel, DC electric, AC electric and multisystem locomotives were launched at the 2010 Innotrans trade fair.

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 border working; this design resulted in numerous orders from both state and private railways, as well as rail leasing companies, primarily in the European Union area.

Siemens identified the potential for further growth in the market, particularly in trans-Alpine freight (Northern Europe to Italy), railfreight from northern European ports into Europe and from Baltic ports into Russia, as well as the potential for growth in newer members of the European Union (Poland, Hungary etc.).

The design incorporates elements from previous Siemens locomotives—the train control package and traction control system are from the ES64F4 and ES64U4 Eurosprinter models respectively, whilst traction system is derived from the ER20 EuroRunner. The cab and replaceable front end (buffer-bar) derives from the latest Eurosprinter model i.e. locomotives such as the Belgian SNCB Class 18 or Portuguese CP Class 4700.

The Vectron is designed to be easily reconfigurable to a variety of country or work specific configurations; reconfiguration to different safety systems is simplified with pre-designed mounting points for track equipment, modular safety equipment cabinets in the locomotive body and a driver's desk designed for a wide variety of information equipment.

The locomotives are also available in a medium power (5.2 MW or 7,000 hp) version for regional passenger and medium freight work as well as a high power (6.4 MW or 8,600 hp) version. DC only versions are only available in medium power. The standard design speed is 160 km/h (99 mph), which can be upgraded to 200 km/h (120 mph) with the addition of semi-active yaw dampers incorporating a bogie–bogie steering mechanism.
