"Y" Track for the monorail

If you hand one station on the track you have one train, if you have two stations you have one by goer train and so on. You would never have trains crashing because there would only be one train if the tracks connect more than one station. Because of that you would not need any kind of switch, just the "Y" track. It would be nice to also have some kind of track that would either go over or around the mountain to connect Springfield Est. to Springfield.
