On an electrified line, the ability of an AC track circuit to detect a train can be impaired when cross-bonds are connected between adjacent tracks to improve the return flow of traction current. If the cross-bonds are taken to the mid-point of an impedance bond connected across the running rails, the problem is minimised. Where this policy is not adopted, it is very important to know the significance of the various factors affecting track circuit design. A brief introduction is given to some key aspects which resulted from a computer simulation and practical tests.
