I think it's about time that the TSW has diesel railcars for local traffic with a corresponding route. I am in favor of the BR 648, BR 632, BR 612, BR 644 or BR 628.
DB BR632 is the unique one because it will introduce Dovetail games to the Polish train manufacturer PESA. Furthermore it can run on Main Spessart Bahn Aschaffenburg-Gemünden as the Aschaffenburg HBF Port Shuttle. DB BR632 on Main Spessart Bahn needs RMV decals. Video is by Alexander Emmerth and comments are in German Language
I suggest a route for the Br 644 and the Br 620. Mabye you like it "Tsw 2 Suggestions: "eifel Route" Cologne Messe/deutz - Kall | Dovetail Games Forums"
It would be really great if there was finally a German DMU. If I could choose one, it would be the DB BR 642 here
I agree completely- but I don't think it's likely for the foreseeable future. DTG like routes, especially German ones, where they can recycle and layer in their existing locos and MUs, which means electrified routes. And with few exceptions, DB DMUs only run where the line hasn't been electrified.
DTG should really bring out diesel railcars, since DTG always brings out routes with various Dostos and Dostos slowly get boring on German routes.
