Running Deadwood Lumber & Mine for the first time - From opposite end of bridge, with the bridge down (which it did on it's own as I approached it's signal) I could not get a green signal to proceed over the bridge. Upon investigation of the other end (shown below) I came across Junction 40210 which has an "error" red background and obviously does not actually act as a junction. However, even with it's "error" red background when I set it to green I got my green signal on the opposite end. Does this junction actually serve a purpose working with the bridge?
