It says on tsw2 wiki if you own the following routes you get extra msb(61)and rro(112)time table services.for ks which has only(40)to start.Does this mean only extra services or also extra trains to operate on the route?I heard matt mention something about this in a previous q&a stream but i'm not sure what he ment.
Yes, it means that the trains from those routes will be used in extra timetable services, as long as they are in your preserved collection.
Yes that is exactly what it means, as those routes bexome available into TSW2 you will have additional timetable services added to the the Koln route.
