I'm wondering if that "acceleration" fix means just for the loco or is a physics upgrade for when it's pulling a heavy train?
As for what new US route? My guess is something in the eastern-half of the USA. With Donner Pass, Sherman Hill, Marias Pass, Pacific Surfliner and Stevens Pass being in the western-half, I could see the east getting some love this time.
I remember a past poll of theirs having Mullan Pass and a Chicago area commuter route being neck and neck for the longest time. Even though I personally like freight routes (Mullan Pass), I'm sure the Chicago area commuter route would be the more welcome of the two for a change.
Personally I hope it's either a Florida CSX route or something around the Appalachian mountain chain. Even a route in the swamps of Louisiana would be nice too.
