So, my 3rd rail steamer worked perfectly fine last night. I put her back on the tracks today, and now, train won't move. The startup sounds work, horn works and the smoke unit works. However, when I try to move the train, it won't. Other than that, the only noticeable difference from last night through today is that when I try to quill the whistle, it just plays a few blasts (similar to a Williams true blast horn).
On the Legacy Controller screen, I noticed that in the bottom right portion of the screen, there's an arrow pointing downward instead of the normal directional arrows that point to the left or right. It didn't do that last night and everything worked fine. Does anybody know what's going on here?
