There's an ICE service between Aachen and Cologne that stops at Düren and I try to recreate. There's only the freight path, the S-bahn path, the RE path and the ICE path. The ICE path has no way to stop at Düren, but the RE path forces you to divert at Langerwehe and Horrem even though you don't intent to stop there. This is probably a "Working as intended", but it does break immersion. If it is the case, I'll put it in suggestions. Langerwehe Horrem
