I've asked around on this one, but haven't gotten an answer so I am trying here, too:
There is a subdivision I run on that has a ruling grade of 1.1% eastbound. The tonnage ratings for that same subdivision are less for westbound trains than they are for eastbound trains, which have to contend with the ruling grade. I would have assumed the tonnage ratings would be less for eastbounds than westbounds; that's the case for every other territory I run on.
Of all the subdivisions I operate on, this is the only one with this scenario. Can anyone explain why this may be, or if there is another piece of railroad someplace that has a similar setup?
