Electrification: Its Effect on Signaling and Communications

When an operating railroad is electrified, the propulsion power may produce effects on the signaling and communication facilities which require conversion for compatibility. This paper explains the role of signaling and communications in railroading, describing the needs and economic justification. It describes the effects of electrification and the requirements for conversion of facilities. It suggests a systems approach to electrification, on the basis that proper coordination of propulsion power with signaling and communication facilities can materially improve the return on investment for electrification.
