If you are going to spawn AI trains in sidings, be careful with the size and switches are aligned. In this case, my train was too long for the siding. The northern switch wasn't properly aligned. So the train broke a nuckle when the crew tried to move close to the southern signal. I was unable to delete the train.
This made for an interesting session. I had to keep traffic moving on Seligman. So I routed trains around it. Here my Z-CHILAC met H-BARPHX. My train stopped for less than 5 minutes, but I could feel the pressure a dispatcher might endure. I heard UPS isn't too kind about late trains.
I wish we had articulated cars. I'm using well cars, but this game could really use these sets. The well cars are heavier.
