There's a bug with the F7 the brakes doesn't seem to work unless you put in Emergency and it's hard to start back up. The HUB the Speedo seems to jump from 15mph to topspeed and when it does that at 15MPH It makes it look like you're over speeding and goes red. And is there more services out there on the Timetable on the next update.
Check the brake cut selecter in the trailing locomotive. Like the other american routes. Than the brake works, it ins’t a bug.
