CATENARY SYSTEMS FOR HIGH VOLTAGE A-C RAILROAD ELECTRIFICATION

Following reference to international applications of high voltage a-c systems, the paper reviews the development of the catenary system used in Great Britain. The influence of special characteristics of American railroads on the selection and design of catenary systems is discussed. The processes involved in electrifying a conventional railroad are reviewed and recommendations are made in respect to the adoption of high voltage a-c electric traction in the United States.
