Whilst playing tonight, I noticed some oddities with two signals I past. The OFF indicator was not illuminated when the corresponding signal was at a proceed aspect. The other was the signal prior to Rochester, the feather signals were displaying all route optionals
I do wish the OFF indicators worked in game. I have never actually seen one illuminated in game. Also are you sure the feathers are illuminated? Could it be another light source (like the sun) reflecting off it? I can't be sure. If they are all illuminated then that is weird!
The OFF indicators appear to be new to the game with it first appearing on Birmingham Cross City. (At Duddleston).
