family of locomotives. A more affordable, basic version called ''Smartron'' was introduced in 2018.

Background and design

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 Eurorunner family of locomotives are a series of medium- to high-power diesel-electric locomotives built by Siemens for the European market. Introduced from 2002 onwards, they share design characteristics with the successful Eurosprinter ran ...

. The cab and replaceable front end (buffer-bar) derives from the latest Eurosprinter model i.e. locomotives such as the Portuguese CP Class 4700 or Belgian SNCB Class 18.

Design

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 () version for regional passenger and medium freight work as well as a high power () version. DC only versions are only available in medium power. The standard design speed is , which can be upgraded to with the addition of semi-active yaw dampers incorporating a bogie–bogie steering mechanism. Since 2022, the locomotive can also be ordered with a top speed of 230 km/h. The main body of the vehicle is self-supporting, consisting of an underframe of three longitudinal

section is also a separate part, which allows replacement if it is damaged in a collision. The main compartment of the locomotive contains the electrical equipment except the main transformer and batteries which are located below the frame. All electrical components are placed in predefined locations on either side of a central aisle connecting the two cabins with each mounting position being reserved for a single type of equipment. The bogies transmit tractive force through a central pivot. The traction motors are flexibly supported by the bogie frame, and are connected to the wheelset mounted reduction gears by a multiple disc coupling. A full hollow shaft (folded cardan) drive system is also optional. Mechanical braking is via wheel-mounted disc brakes. Electrical regenerative braking is also used. The locomotives can work in double, multiple and push-pull formation with other Vectron, Eurosprinter and Eurorunner locomotives as well as some other locomotives fitted with the same

equipment. The design also allows single cab version for use in permanent double coupled locomotive working or for use with passenger trains with a blanking module replacing one of the cab ends.

Diesel engined versions

Siemens Vectron Dual Mode 248 001 in Brake (Utw

A fully diesel powered version was launched in 2010. The design uses a , MTU 16V 4000 84R engine. An electric locomotive design with 180 kW diesel engine for shunting operations was presented at the 2012 Innotrans trade fair. In 2018, a dual mode locomotive was presented as a combination of electric and diesel locomotive. The new locomotive weighs 90 metric tons. The locomotive is designed to operate on a 15-kV AC electrical system and is equipped with the PZB train protection system. Regardless of its operating mode, the locomotive develops a rating of 2,000 kW at the wheel rim. The Vectron's diesel tank holds 2,500 liters of fuel. The locomotive's top speed is 160 km/h.

A preliminary certification for some DC version locomotives in the Czech Republic was reported shortly after. The permanent authorizations for the MS and AC versions were granted in March 2015 for the Czech Republic and in May 2015 for Slovakia. In July 2015, the DC version was homologated for Italy. Since August 2015, the MS version is homologated for Poland. The homologation for Croatia and Slovenia was published in September 2015. Since February 2017, the MS version is homologated for Italy. A Siemens press release on the occasion of 500 sold locomotives revealed that homologations also exist for Bulgaria, Serbia and Switzerland. The MS version was homologated for the Netherlands in September 2017. The diesel engined version Vectron DE is homologated for use in Germany since September 2014,
