Even the path is clear ahead of me on the map, the next signal is red and says. Denied. Move up to signal and wait. Why do I get that / what does that mean? Please and thank you
why do you get that? because the signal is red, duh... what does it mean? it means what it says. move up to the signal (otherwise you might also occupy the section behind you) and wait until the aspect changes to something passable.
looks like you are being moved into a passing loop, signal will clear to yellow when your close enough with a low enough speed. At the following signal expect red and a train from behind you to pass.
Which route is it? Never seen 'passenger passing loop' as a way point before, so am curious. Normally they have names, Claypole for example on ECML.
Not sure of all Routes with Scenarios or Services but this screen shot was from: Route ID = East Coast Main Line (PDB). Scenario ID = The Fact Controller. -- There are other scenarios with this same issue on the same route where it was more annoying, like ex in the snow (I do not recall the names but the weather).
