I've been trying to play a couple of timetabled trains and few of them are light engine movements on the West Cornwall Local DLC. I am playing on the Steamdeck. I leave Penzance station and head towards Longrock Depot however it says 200 yards to next signal which is red, although I'm going to pick some coaches up. I approach 2 Ground Shunt signals both showing red. I try to contact the signaller but it won't let me. If I pass the signal at red it fails the task. I'm really stuck.
