no we are not talking about the same thing in two threads. one is about the way most lets players play this game (who sadly hardly ever use single lines with passing loops), this is about the signalling logic of train fever which really interests me since i’m a real train driver. 😉
what you’ve just desribed is exactly what i would love to see in video because i specifically would like to know where the gridlock builds up. the way steve earlier described the signalling logic would lead to trains entering a single line section from two sides if there were signal blocks along the single line section, which would be a catastrophy really.
the way you describe it means that train fever signalling is aware of the single line section and holds trains back from using it if trains couldn’t clear it, which would be terrific.
