Abridgment of catenary design for overhead contact systems

THE rational mechanical design of any overhead contact system must be based upon certain fundamental rules of mechanics, usually those dealing with statics, or forces in equilibrium, applied to the physical characteristics of the track alinement. Theoretically a problem for the civil engineer, the general solution and detailed application of the design has been assigned to the electrical engineer in most cases, as the number of papers presented on this subject would indicate.
