Express box brake system layout

Bud Rindfleisch

Does anyone know of any diagrams or plans showing the underfloor layout of brake components, piping and train and steam lines on express boxcars like SP, and DL&W 40' steel cars? I'm guessing the reservoir, cylinders and AB valves had to be passenger train compatible.
Appreciate any help.
