The timetable for the S-Bahn services around Munich are so tight, you will never be on time, even if you try to speedrun it. You can even see the trains getting stuck in traffic jam and only getting forwards slowly, when you stay in the game for 5 to 10 minutes. This is unacceptable and has been in the route pretty much since release! I think you should add one up to 5 minutes between drive time between the stations, otherwise it is impossible to stay on time. Edit: Okay it IS actually possible to stay on time if you really try yourself but seeing the AI getting stuck is pain, so do something please.
It is the realistic timetable, I don't think that DTG will make it unrealistic just to make you on time
A little late, but it would be a great idea actually. I found myself struggling out of munich. The 1 minute timer to setup, open/close doors and reach the next station that is close to a kilometer away is impossible unless the train teleported there.
