TRACK CIRCUITS AND NEGATIVE BONDING
The paper discusses crossbonding of running rails to improve negative return path for propulsion current and to minimize electrolysis to adjacent structures. A standard application method is investigated to prevent interaction with railway train control systems when rails are used simultaneously for single rail track circuits or double rail track circuits. Application to audio frequency track circuits is discussed, and the effect of cross- bonding on broken rail protection is examined.
