Rhein-Ruhr Osten is one of the shortest (and most disappointing) German routes in Train Sim World. It only includes two forms of motive power - the Deutsche Bahn BR422 and MRCE BR185.5 - and a stupidly short route that only runs for around 31 kilometres from Wuppertal-Steinbeck to Hagen; it's pathetic.
We also have the Vossloh G6 diesel shunter, brought to TSW by Train Sim Germany as an add-on for Rhein-Ruhr Osten. This locomotive is very well-made, in stark contrast to the route itself.
