Owingto its construction, it can be transportedeasily in ])arts and assembled on theground along the line. Poles can be made all in one piece to any required length u]i tn fifty feet. The company has installed a number of these poles on the lineof the Union Railway Company, in New York, where they havegiven entire satisfaction, and where they can easily be inspected by^isitors to the convention this TRIPARTITE POLE Recent Developments in Magann Air Brakes The Magann .\ir Brake Conqiany. of Iletroit, Mich., announcesits acquirement of a new system for use in connection with themultiple-unit system of train propulsion.
