Great go~with here ICONites! Circa 1956 PRR engineers rule book and manual for conducting trains. All pages are in great condition as is the cover, it has some wear but no tears or rips. This manual covers signals, signs, lights, speeds, rules of engineering, etc....detailed drawings of signage, engine classes and crew information, everything you'll need to know and learn to successfully engineer a train. Spine of this manual is excellent. Very nice piece of liturature for your insulator and railroadiana collection. First mail to me.... $22 shipped in USA/Canada, other countries I will assist with shipping costs.
