I created 2 lines for my 2 train stations. One in each direction. But after a minute they just vanished. Not sure how to reproduce yet.
And the train line details for 2 stops only show 1 stop in the details. You can't see how many people wait at the second stop.
I used the default first train station and the new classic station from the new DLC pack.
