It’s not possible to get a gold on 5G61 Empty to Depot on East Coastway on Xbox as the final position marker is in the wrong place I believe being right at the buffer. 2. When the train hits the buffer it’s still showing over 200 yards to go as you are in the front cab which is at the other end 3. If you try to go to the other cab (the rear as you leave the station or front as you get to the buffer you are given a warning about ending the service 4. I’ve just tried reversing out of the station (after ignoring the warning when sitting in the back cab) and managed to complete the service within a yard of the target BUT I got no medal!
I've found the same on the earlier services from the depot to get the train ready for service. The one I did was an 8 car train, wonder if the fact that it is a different unit when you swap cabs is confusing things...? Edited to add that this was on the PS4.
