As TSW2 it has several German routes, with a variety of freight locomotives DB BR182, DB BR155, DB BR 185, - plus also the "switchers" for shunting -, and other new ones coming... I would like to have more variety of freight cars. For instance there is a lack of a usually nice design freight car: Hopper I know there are the coal ones - you must have the BR155 - and the cement ones - you must have the BR 363 red - cement ones. (in this case are all grey with no letters). But what about other kind of them like grain ones, etc. There are also some on DB livery, then DTG it have the license. The DB BR187 will be coming according to Roadmap, so it will be great if a new hopper freight car be included with it, like it happened with the BR 363 Please see the pictures:
There's also Zags tanker wagon which is actually used to transport liquefied petroleum gas those are also common on SKA with existing locomotives including DB BR182 to Aachen West which is actually past the depot building in Aachen. Another one they can add are refrigerator box cars I like the Ibhhps used to transport beer. 2 axle version of Main Spessart Bahn Habbiins wagon the Hbbillns also used to transport paper rolls
