The ER20 BF / 20 BU locomotives are based on the Eurorunner platform for Technical data diesel locomotives. Wheel arrangement Bo‘Bo‘ Track gauge 1,435 mm They are suitable for light to medium- Weight 80 t (with 2/3 consumables)* heavy freight transport on main and branch lines as well as for high-quality Axle load 20 t passenger service. Length over buffers 19,275 mm Wheel diameter (new / worn) 1,100 mm / 1,020 mm Central features of the vehicle concept Structure clearance gauge UIC 505-1, Figs. 6 and 7 are its simple structure, which consists of a few prefabricated modules, and its high Maximum speed 140 km/h / 160 km/h (optional) degree of ﬂexibility. It enables individual Diesel engine rating 2,000 kW customer-speciﬁc requirements, such as Starting tractive effort 235 kN (at 20 t axle load and µ0 = 0.3) equipment with a train power supply, Electric braking power 1,000 kW (at the wheel) to be met through the modiﬁcation or replacement of only a few built-on parts.
