Instead of equipping electric locomotives with just a diesel power pack (last mile package), which enables them to be used independently of the driving current, for example on sidings, Stadler developed the EuroDual, which carries a full-fledged diesel engine. The EuroDual, run as the 159 series, runs purely electrically under the 15 kV-16 2/3 Hz system as well as in the AC and DC networks commonly used in France. Depending on the operating mode, traction power between 6150 kW and 7000 kW is available under catenary, the 16-cylinder Caterpillar CAT C175-16 diesel engine has an output of 2800 kW and generates the energy for the six electric traction motors. Depending on the reduction selected by the customer, the locomotive can reach 120 to 160 km/h. In Germany, the HVLE and the leasing company European Loc Pool each procure ten, ITL / Captrain four EuroDual.
