Have you asked the signaller for clearance? I've not done this route but could be a way to get through?
There’s probably about 100 tutorials in the game, considering the number of DLC route and loco add-ons. It would be helpful if you use the Escape key to see the specific name of the tutorial you’re playing. (If it’s “Freight Exchange,” that’s a known bug and that fix should ship with the update that’s coming out when Rush Hour ships.)
The reverser is set forwards but the arrow for the goal is pointing backwards. Try checking the map to see if the goal is ahead or behind you. If it is behind, you will need to either set the reverser to go backwards (easier) or set up the other cab to go forwards (harder), if there is one.
Okay everyone I actualy found someone on youtube make the same tutorial and I should have switched tracks in the begging cuz after imma just back up
