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.
Exactly, and in fact, the SP cars did have AB-1-B gear.
