    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 range of electric locomotives, also built by Siemens.

    The main initial order for these locomotives was for 100 of the four axle ER20 for the Austrian Federal Railways (ÖBB) and designated ÖBB type 2016, and commonly called Hercules, further smaller orders from smaller railway companies have also been fulfilled.

    Later six axle versions ER20CF were produced for Lithuanian Railways.

    A higher power version ER30 is also offered but has not resulted in any orders as of 2010.

    Production of the Eurorunner ceased by 2012, replaced by Siemens Vectron diesel engined versions.


    The locomotive is designed to be made of as few parts as possible, and is of modular construction, with separate components (engine, electronics etc.) kept in separately fabricated units and are designed to be easily replaceable.

    Marketing by Siemens has heavily emphasised the locomotive's energy saving characteristics, as well as the technology used to reduce particulate emissions.

    The locomotives have a supercharged 16-cylinder diesel engine of the MTU 4000 series developing 2,000 kW of power which drive a three-phase brushless alternator. At idle 8 of the 16 cylinders can be turned off reducing fuel consumption and emissions.

    The three phase electrical supply is rectified to DC to supply a pulse width modulator, which in turn generates a three phase electrical supply to the traction motors (which are of the induction type) - the four traction motors are connected in parallel.

    Electrical taps from the main DC power supply also provide power to other electronically controlled power supplies including those that power the cooling fans (also known as 'blowers') at 440V 3phase 60 Hz. The power supply for passenger operations (coach heating, lighting etc.) is optional and is located separately under the main frame whereas the rest of the electronic equipment is mounted in the body of the vehicle.

    In addition the electrodynamic brakes can charge both a battery pack, as well as high capacity capacitors - meaning that energy absorbed on de-acceleration can be re-used later on. This feature saves emissions and fuel consumption - if the batteries and capacitors are full a roof mounted set of resistors provides the remainder or additional rheostatic braking. The maximum electrical braking effort is 100 kN (22,000 lbf). For additional braking a pneumatic braking system is included.

    The locomotives are equipped for Push-Pull operation (with Driving van trailer for instance) and for multiple unit operation (see Multiple-unit train control.)

    Eurorunner ER20 C

    The six axled locomotives have a number of changes in addition to the change of bogie type: both mass, tractive effort and braking effort are increased. The modularity concept used in the 4 axle versions remains unchanged. One notable difference between the two is that the ER20 C models have one pulse width modulator (electronic power supply: generic term 'inverter') per bogie (i.e. 2 ), whereas the ER 20B models have only one pulse width modulator in total. In addition the arrangement of modular components is changed from the Bo'Bo' versions.[8] This model also sports a water closet.

    Siemens technical documentation mentions an ER30 which appears to be a variant of the ER20 CF model, with the possibility of a higher operating speed - it is describe as being suitable for passenger and freight operations.
