Excerpt from Transmission Systems for Heavy Traction; Types of Collectors for Heavy Traction; Types of Railway Motors; Speed Control; Single-Phase Speed Control; Electric Locomotives; Operation Instructions; Brakes; Signal Systems The contents of this volume relate to systems for the trans mission of electrical energy for the propulsion of electric loco motives and electric trains; to the apparatus used on the locomotives and trains for collecting the current, for propulsion, for acceleration of the speed. And for braking; to instructions for the Operation of the locomotives and trains; and to signal systems used in connection with heavy electric traction. The general features of the transmission systems are explained. Third-rail and catenary construction are treated in consider able detail. Types of collectors suitable for the collection of large currents and for high-speed service are described and illustrated. Instructions are provided relating to the com mutating-pole motor and to other types of direct-current and alternating-current railway motors. The important subject of speed control receives a most comprehensive treatment. Numerous multiple-unit wiring diagrams, some in four colors, aid in the study of this complex problem. Three sections are devoted to the subject of brakes. The operating features of the signal systems used on electric railroads are explained. The method of numbering the pages, cuts, articles, etc. Is such that each subject or part, when the subject is divided into two or more parts, is complete in itself; hence, in order to make the index intelligible, it was necessary to give each subject or part a number. This number is placed at the top of each page, on the headline, opposite the page number; and to distinguish it from the page number it is preceded by the printer's section mark Consequently, a reference such as 16, page 26, will be readily found by looking along the inside edges of the headlines until 16 is found, and then through 16 until page 26 is found.
