Hello, here are some ideas to extend the already existing lines (New Itinerary). 1.Ruhr Sieg Nord extend it to Siegen Hbf so that this line becomes Ruhr Sieg Line. 2.Merging of the Ruhr-Sieg Nord and Rhein-Ruhr Osten line (which would be free for those who own Rhur Sieg-Nord and Rhein-Ruhr Osten).
1. Nice idea. Especially when combined with 2. 2. I completely agree, but if you look a bit you see there's already a quite big thread about it. I do differ in regards to it being free, if it increases the chances, because it is a bit more work needed than one would think, I, and many others, would be willing to pay extra for that. Not full price, but a bit.
