Abstract

A method and apparatus for transmitting an information carrying signal, such as an electromagnetic frequency signal or an acoustic signal, through the tracks of a railroad to a remote position on the track where the information is extracted. The extracted information can be used to relate speed and location of trains, location of obstructions, and or track conditions. The in situ track (10) is evaluated using an autoranging digital multimeter which establishes the resistance between two opposite rails (12, 14).
