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 440 V 3-phase 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.
