On the way to the Cumberland Hump Yard in scenario Y109 westbound set out and pick up the 2 locks parked in the line adjacent to the line I was working on starts up and then follows on the same track thus not being able to go to my destination. I've tried this scenario twice, the first time after over an hour's work another train with 50 cars in tow came onto my track and the entire game was lost. Thus happens in the scenario approx 19.17.
