This 8 1/4 x 10 5/8”, 160-page guide to railroad signaling in the U.S. simplifies the utterly bewildering array of mechanisms, procedures and rules that have evolved since the 1830s to promote safety, impose control and disseminate information on America’s railways. In addition to providing a brief history of North American signaling from the 19th Century onward, Solomon provides 140 color and 15 black and white photos of equipment and explanations of not only how it works, but how it is used and what it all means. Solomon also explains how trains on the same route are given precedence or placed in pecking orders and how routes are broken down into digestible segments called “blocks” that help dictate the speed and manner in which a train is driven. The result is a fascinating look at the development of communication on the rails. Major manufacturers of signaling equipment are represented. Softcover, 8 1/4 x 10 3/4", 160 pages, 125 color and 25 b/w photos.
