This has probably been said a lot and you are all already aware of it but I don't get this so I am asking. Why are trains still filled with people when you go to the depot at night or when you arrive at your final stop. This seems like a problem that is so easily fixable. When I drive a timetable route at rush hour I have an empty train (while it should be filled with people). If you can have an empty train on a timetable service why can't you have an empty train on a depot service. This is so annoying and completely ruins the immersion. I really hope this will be fixed soon!
It is a bug. In one of the streams we were told they think they have a working fix internally but it had not been fully tested. Personally, I think if their fix works we will receive it with the UE 4.26 update.
Could be if they made it empty on the depot service it will never fill with passengers when it goes into a regular service?
