I have usually seen the brake cylinder, either for an AB or a K brake,
mounted on the side of the centersill of a steam era freight car. The
cars in question are the prototype PRR G-22 gondolas. Kohs & Company,
Inc. is importing an excellent model of the G-22b container car in "O"
scale, and has some pre-production model photos at www.kohs.com. These
models have the brake cylinder mounted to the steel floor of the car -
can this be correct? I have been under 200+ freight cars measuring
them, and I have NEVER seen a brake cylinder bounted to the floor of
the car! Thanks for your response. A.T. Kott
