The Catenary System and Power Supply Facilities of the Muskingum Electric Railroad

Tbe transmission system substation supply facilities, and protective relaying of the Muskingum Electric Railroad (MERR) are outlined. MERR is a 15-mi coal hauling line representing the first American application of techniques used in the rapidly spreading electrification of railroads in Europe and Asia. The substation and catenary facilities described were developed to provide ideas, examples, and cost samples to show what can be done in electrifying main-line railroad freight service. Catenary for the project is the first 25-kV 60-Hz system installed in the United States. Three types of catenary hangers were used to provide a measure of comparison of different ideas. Installation procedures are described in detail.
