Abstract :
TRACKS of electric railways, being continuously in contact with the earth, allow current to leak into the earth, the track current thus varying continuously at various points along the length of the track, unlike the currents in other conductors of the propulsion system. This paper aims to present a systematic treatment of current propagation in the tracks with a view to providing a theoretical foundation for the treatment of engineering problems in which the electrical behavior of the tracks as a part of the current-carrying system is important.
