Abstract

Track circuit equipment is provided in which the trans­ mitter of each track circuit uniquely identifies its transmis­ sions by impressing an associated data word (38) onto its transmission using frequency shift keying. The track circuit receivers are so arranged that in order to output a track clear signal, a receiver must first have detected on incoming signals a data word (38) identifying the transmitter belonging to the same track circuit as the receiver. Each data word (38) is included in a message structure that also provides a start sequence (35) and a parity section (39). The data word (38) includes respective bit groups providing longitudinal and lateral location information on the related transmitter. Each data word (38) may also include a bit group providing for an auxiliary signalling function such as track-to-train signalling.
