So I was toying around with CBH Trains, along with the 1872 Kimbail Rail Car. While I was coupling, I wanted to find out what the wheel is supposed to do, which turns out to be a brake. Too bad I didn't know at the time it was a brake, so i removed it, then added a new car.
Right now 1872 Rail Car and the BR MK1 Standard are on permabrake, with now way to reverse it. Any help?

It's okay if CBH doesn't make it, but I suggest he makes the Pere Marquette 1225, because a lot of people attribute the train with Christmas.
