Abstract

An apparatus for monitoring the condition of an alternating current track circuit comprising: a sensor (78) for sensing a current in the track circuit when arranged in proximity to, but not contacting, the track circuit; an analogue to digital converter (58) operable to convert the sensed current to a digital signal; and a processor (64) operable to receive the digital signal from the analogue to digital converter (58) and to perform signal processing on the digital signal, said signal processing providing a parameter indicative of the condition of the track circuit. Alternatively, time domain characteristics may be monitored using digital or analogue processing.
