Others here will have to help me, but I believe it was one of the John Norwood D&RGW books with a great accounting of a station agent(Norwood?)
having to snowshoe it from Cumbres in the blizzard of 1952 to a stranded engine and crew several miles away. At one point he trips, and it turned out to be the telegraph wire!!! I don't know the book but that account is a classic, especially for winter railroading. He also had to crawl on hands and knees across Cascade creek trestle before finding the engine.
