Abstract:
A wayside communication system for transmitting coded current signals through running rails of a railroad track between wayside control devices. A power line common to the wayside control devices is used as the return path for the current signals. The system features train and broken rail detection. The system allows sending signals long distances since rail to rail current leakage is no longer an issue.
