Norm,
I've encountered a bug with one of the Holly Sub paths. "Pontiac2GM Local" freezes on start up. When I tried verifying the starting state for that path in the AE, it froze that screen, too. I've found no similar problem with other paths. I'll keep digging into the problem on my end and see if I can come up with a fix.
(I also noticed the "Pontiac2GM Local" path starts westbound and loops past Pontiac North Yard, GM and Junction, then ends at Pontiac Yard. In AG, the route is the opposite, with the workorders listing Pontiac Yard, Junction, GM and North Yard, in that order.)
