I have been at the TVL route driving class 31. It was some service which calls all stops. When approaching the station Tees Side Airport I started braking late and overshot the station so that not single coach was on the platform range. So I reversed the locomotive into the station and by doing so I have passed the signal and corectly stopped the train at the station. When finished loading of passengers I could not proceed passed that signal because it was turned red when I passed it in reverse movement. So I checked the map and nothing was in front of me. I than contacted the signaler and they did't want to let me pass. So is this normal like it should be, or maybe I did something wrong in the process of reverse action?
