Re: Express box brake system layout

I'd imagine that the same brake gear could very well have been used. Troop sleepers used two sets of Wabco AB-1-B brake gear. It is similar in appearance to freight AB gear, the only difference being that the control valve was fitted for graduated release to work in passenger trains.

I don't have a drawing for the SP cars, Bud, but as far as I can
tell from photos, the brake gear is LOCATED the same as on a freight
car. You're right, the brakes had to work in passenger service, but
did not have to be the SAME as passenger brake gear.
