Union Switch Signal Company Co

4.9/5 (18985 ratings)

Description:Excerpt from A Catalogue of the Devices and Their Parts Since the organization of The Union Switch & Signal Co. a large amount of work has been performed in the interlocking and block signaling field. A few statistics illustrating the scope of our business may prove of interest, and will certainly be instructive as showing the widespread and growing demand for safety appliances on railroads. The Saxby & Farmer Improved Interlocking Machine is of the type which is most widely in use throughout the world, and almost to the exclusion of other types on this continent. More than 900 distinct plants, containing over 16,000 levers, have been built by us, and equipped with this machine. Nearly every railroad in the North and East maintains at least one of these installations, while most roads have a great many more than one. For instance, on a certain great system, there are in service about 200 machines that contain in excess of 4,100 levers, while on one of the large railroads in the East there are 175 machines, containing 2,200 levers. The Electro-Pneumatic Interlocking Machine, which is the highest development of the idea yet reached, is in use at 46 different points, comprising 1,600 levers. A large proportion of these plants are at the most important terminals in the country, where the performance required of them is of the most exacting kind; the Union Station at St. Louis; the Pennsylvania Railroad terminals at Jersey City, Philadelphia and Pittsburg; the complicated grade crossing at Stewart Avenue and Twenty-second Street, Chicago; the Philadelphia & Reading Railroad terminal at Philadelphia; the Chicago & Northwestern Railway terminal at Chicago, and the Boston & Maine Railroad terminal at Boston are amongst some of the larger places. In Electro-Pneumatic Automatic Block Signaling a most encouraging progress is to be noted. About 1,500 signals have been erected, which, placed one third of a mile apart, about the average distance, cover five hundred miles of road.
