Most railroads issued standard drawings detailing track maintenance materials all the way from spikes to camp cars, including roadbed specifications, detailed drawings of various switches, and line-side structures. This Pere Marquette Maintenance-of-way Standards book was issued in 1930. It was the bible for the roadmaster as he kept up the track I those days on heavy traffic and heavy wear-and-tear on track by steam locomotives. This is a 140 page reprint on 8 ½ x 14 paper. This is a MUST for PM Prototype Modelers!
