The only thing I found with the activity was that it started too late in the day at 3pm. By the time I'd got most of my work done it was going dark. So, rather than saving the activity and it obviously still being dark when I reloaded it, I parked the shunter, left the sim running and went to bed. Came back to it today just as it was coming light and finished the job. All the coal is down at Blythe Bridge and all the empties are in the screening plant.
It's a fantastic and very open ended activity on a fantastic route.
