Abstract
A fixed transmitting station is employed and the system allow high speeds of signalling. Two conductors are used, crossed at intervals to avoid coupling with the rails. These can be one in the centre of the track and one by the side. The vehicle coil receiver is inductively coupled with the central wire. An alternative is to use a centrally situated wire and the rails for return current. cover is made for track point systems where special fittings then needed.
