hi there, new to ps4 train sim, but been around train and flight sim for many years. Just getting to know the tutorials for the west somerset line, and on 50% of occasions walking around the class 09 to set the front and rear markers, it stop at 1 yard, and will not let m set them. i have to close the tutorial go to main menu then go back to the 09 start stop tutorial. that usually works.
Sometimes the cursor is not in the correct place, when this happens, move your character and cursor around the marker lights until the prompt appears. It isn't a glitch I believe, it's just the game being fickle about where they can be activated from.
