A Suggestion of mine would be this, Lines The main Line of this route would be the ICE 503 heading from Berlin to München and back. There are also other ICE and Regional line like for example the FEX. New Locos Driving in the ICE 503 line would be the ICE 4 (br 412). Optional but it would also be nice for it to have the ''Deutschlands schnellster Klimaschützer'' included too. Also the br 147 would be driving in this route too. It's basically the 187 but operates passenger Services. Stations The first station would be Berlin Gesundbrunnen. Heading over to Berlin HBF (tief) and then Berlin Südkreuz. Now exiting Berlin and arriving in Lutherstadt Wittenberg. The all redesigned train station. Finally arriving Leipzig Hbf where another driver will be taking over the train. Conclusion This would be a great Route since it not only shows the beautiful views of Berlin, but also the views of Lepzig with it's great Central station!
I like this, in general ideas with Leipzig I like a lot since it's very underused...only 1 route and we STILL have no route involving Berlin However, I believe there could be plenty of additional rolling stock added to this.
