Hi, my bad, i don't understand how to connect two station using subsurface. Both stations (start/stop>loop) are outside, but main track is below the ground. I can't select any station because the train cannot reach it, but driving the train manually works fine. No signals used yet, since its a single train test.. If i add the subsurface option, it just move underground and thats it, it stops right after entering undergound, i cannot even move it manually after that. Can someone provide a clear example on how to connect stations using this mod? Either i'm missing something, or something else is wrong. Thanks for your time.

You can select stations in the schedule that are not reachable for now.
Make sure you have a station underground. It's currently not possible to have two consecutive teleporting stations in the schedule.

My current setup is this: Station A pick up > Station B Drop, single rail, no signals, train whit two engines (back/forth). I also added two station undergound thinking about that, and didn't work. Unless i need 4 (for back and forth both ways), or if theres a correct setup for that, i'm not up for trial and error until it works. If trains needs a specific settings, it should be noted somewere in the mod description.

My current setup is this: Station A pick up > Station B Drop

You need to tell the schedule to go underground with the corresponding station (the 0 /\ \/ 1 thing). Then you need at least one stop which is underground. Then you need another layer-switching stop to tell the train to go overground.

Mh thanks, i got it working now. Needed a more clear instruction, thanks.
