Oh interesting.. I wonder if that mod is built into the map.. I would try starting a new save game on that map with just the placeable track and the locomotives enabled and see if it still has issues?
yes the Barn is part of the map and I laid track around the map trains run on it just fine,it takes around 45 min to run around It's just the switch thing I hope we can fix it for this is a great map for your Mod here a link to just a video of it I stop working on it till the switches work
