Back on The MSTS Wagon ( so to speak ), you'd have to have invisable/"hidden" Track Nodes every so often thanks to a bug within the Program that made you break the train/un-couple for nothing if you didn't go past any switches for a bit. Example's like coming out of a rocky valley or mountain area to an industrial switching area or vice versa, & if it didn't have those invisable Track Nodes your train sometimes ( even with the 5.4e.7N double couple settings ) would basically be like,"Bye,bye" Another's @ a Port where you'd pull the train all the way around & would come back to the same track ( such like The AL Port on NS Birmingham Route ). Do you still have to worry about this in ORTS as well?
