hey i don't know if it means anything at this point or not but i thought I'd let you know either way. At coordinates : 2060, -1240 , which is basically the long track going thru the middle of the map around the desert water fall area there is a T- Crossing that when you cross over it the train will glitch and swap over to the opposite side of the track. this happens coming from either direction.. i think you laid out the track in the same direction for the junction there. just a head up. also in case you didn't understand coordinates yet .. in update 6 in the map you have coordinates that show on the top right.. also you can navigate to any area by typing them in there as well. so yeah thought it should help pin point the spot.
