Somebody else got trouble with this?, I encountered a problem: After I uncoupled the caboose and after that several more wagons I got a red signal somewhat further up the track after uncoupling the wagons. There was a train coming from the other side and it stopped about 50 yards from my train, head to head. It can't go on the track where I am obviously but it can't get on the track next to me because the caboose I uncoupled is there. So there we are. Stuck. Somebody else got this problem?? TIA, David
