I have changed from signal heads to signal masts.? My train goes around the loop in Dispatcher automatically but doesn't stop in the station as I want it too.? The 3 physical sensors show up on the?layout panel, as the train goes around, but not the internal sensors.? How do I set up the physical and internal sensors on the panel?anchor points,?so that it will follow the train around the blocks in red on the layout panel and stop in the station?
