Describes a method which allows the position of trains or other vehicles to be established purely by reference to the signals being transmitted through a leaky-feeder system. The basis of the location principle is that a radio signal being transmitted from base to a mobile or personal set (or in the opposite direction) can be systematically modified during its passage through the leaky-feeder system in such a way that the location of the mobile set can be deduced from the total extent of the modification observed in the received signal.
