509 of RWE Rheinbraun pulls a train of empty coal wagons to the opencast mine
Hambach on 10 October 2001. Just behind the side window is a control desk which
faces backward. It (or the other one at the other side) is used when the loco
pushes the train. The control desk for the forward direction is in the middle
of the cab. Only one of the two big pantographs is used, the other one serves
as a spare. The two little tilted pantographs on the sides are used under the
loading facility, where a normal catenary is not possible.
