The DB BR 420 for HMA is something that TSW2 really needs. But it would be even better, if it also includes S-Bahn Köln version, which adds services for SKA. SKA has IMO the best route layering so far, and if it also features services for BR420, it would get even better!
Won´t come, unfortunately. It has been confirmed that there will be one livery of the train and that one livery only (The one for HMA obviously). We will have to use the livery editor and scenario planner to do so i guess.
DTG will do it the easy way layer the HMA DB BR420 onto SKA and give it S12 S Bahn Rhein Ruhr timetable. Also if S-Bahn Frankfurt is made the same HMA DB BR420 will get a time table mode for S8/S9 Hanau to Wiesbaden via Frankfurt Airport Regional Station at the same station HRR DB BR425 will be the RB58 Russelsheim Opel to Laufach train.
It wont be possible for a BR 423 livery, because DTG would have to redesign the entire Train, since the BR 423s used on the S-Bahn Köln are the unmodernized ones.
If they're unmodernized, what is their difference to modernized ones? Maybe destination boards? Interior?
The interior is the diffrence as well as the Destination Boards. + There is no big Lounge Area at the Front and rear of the trains
Well if the 422 and 423 interiors are similar along with the pis, it shouldn't be difficult to do then
