I really don't know how to use the new signals and I am not an expert in British railway signals. Can someone create a guide? I think that would help people like me and mainly new players.
I wrote some ingame help files that explain some of the functionality, however those are still incomplete. Otherwise James made some videos explaining some of the signals.
Indeed: I am planning to produce more videos in due course, although doing so takes time that I could be spending fixing bugs, so it is always challenging to prioritise.
