hallo ! At one point along the route, I have to hook up 7 carriages, but the light is red and I can't move. Any suggestions?
You must contact the dispatcher and then wait for them to set the switches and change the light. As how to do that by pressing the phone. If you need info on how to do that with a keyboard shortcut or game controller, you must tell what system you are on. For EX since I am on Playstation (PS4), I press and hold the O button.
