I needed to weld track together, it made 2 little grey boxes on the floor, when testing a train on the line, the game backed out saying something about a switched junction?
When you go to drive your train or tram you can look at the 2D map by pushing 9 on the keyboard If the route is set correctly you have a blue line but if points are not set the blue line stops The train I'm driving is in Red in a Green Platform but the track to the right the points are not set for me
