Ruhr-Sieg Nord is very good route, but a bit short. It contains 61 kilometers of the line from Hagen to Finnentrop. I want to see the full line of Ruhr-Sieg from Hagen to Siegen, at least as two separate parts. Route length between Finnentrop and Siegen is just 45km, so it would be a realistic route for TSW2. Hagen - Finnentrop line is named Ruhr-Sieg Nord, so this one would be Ruhr-Sieg Süd.
