Stadler Rail EuroDual

The concept of having a full-fledged diesel and electric locomotive in 1 is not new – Think CAF Bitrac or Bombardier ALP45 Dual Power – and technically not that revolutionary, but as with most innovations, you need the right time, plus a customer with a business case in which the product really will be profitable.

It was the HVLE that initiated the project around six years ago, a bold move, and the start of a long period of finding the right manufacturer (Stadler Rail) and negotiate about the final solution (which took 15 months!).

During InnoTrans 2016, a model was on display showing the locomotive design: a six-axle electric/diesel-electric locomotive with a top speed of 160 km/h. Maximum duration power: 7 MW (electric) and 3 MW (diesel). The starting traction effort can be as much as 500 kN. The machine features AC traction motors and IGBT converters. It is possible to order the locomotive as AC, DC or multisystem locomotive. Narrow gauge, normal gauge, wide gauge, all options are open, of course.

In 2018, a successful freight test was conducted in the Perthus tunnel between Spain and France. During the trials, the EuroDual prototype locomotive moved a 2087-ton train on an 18‰ ascent from a standstill. The EuroDual also managed to pull a 1500-ton train at ½ traction power. The norm for the Barcelona-Perpignan route is 1500 tons, which are driven by two Series 252 Eurosprinters, working in multiple mode.
