The first place I try for any PRR equipment is Rob's PRR site...for a basic diagram (drawing): http://prr.railfan.net/diagrams/PRRdiagr...&sz=sm&fr=, then some photo research (when one knows which class/type one is chasing)...Google images have a lot, and can lead to more info. Good luck on an unusual project, and keep the camera batteries charged. Bob C.
