On almost all German trains, there is a timetable screen. On top of it it says "Fahrplan gültig!" and thats it. My suggestion is to actually add all stations on it, and arrows for what side the exit is on. You could also make it so it transmits the next stop on 1km from it (example from real world train: "Nächsten halt: Dredsen, austieg in Fahrrichtung links/rechts"). Also make the buttons on talent 2 for "Ausstiegseite" work, so when someone presses it would say "Ausstieg in Fahrrichtung ..."
It‘s not quite as simple as a timetable. What you‘re taking about is the EBuLa screen, in case you want to look up the system. DTG are aware of it and have expressed the wish to implement working EBuLa screens, but there are no plans for it currently.
