The power of electricity

Draisine? Isn’t that one of those historical vehicles from the early days of rail technology? Far from it. Today’s motorized draisines are an indispensable form of rail transport. They may not run on high-speed routes, but are always found wherever locomotives and cars have to be moved in shunting yards, wash facilities or repair shops and powerful and versatile traction engines are required.

The Rotrac E2 is one of these multifunctional powerhouses. Its special feature: it’s fully electric. The Rotrac E2 was developed by Linde Material Handling for the Rosenheim-based Zwiehoff company. Linde Material Handling designed the entire electric drive system to the specifications of Zwiehoff’s rail technology experts. Prototype development and production of the small series is carried out by Linde subsidiary Proplan.

The Rotrac E2 is already in use with customers like Deutsche Bahn AG, Siemens and Bombardier (Australia) and in Kazakhstan.
