Abstract

The application describes methods and apparatus for control of transport networks, especially rail networks. The method involves monitoring at least part of the rail network(202, 203,204) by performing distributed acoustic sensing on one or more optical fibres(104a, 104b, 104c) deployed along the path of the network to provide a plurality of acoustic sensing portions. The signals detected by the plurality of acoustic sensing portions are analysed to detect acoustic signals associated with trains(205) moving on the network. The signals are analysed to identifying the front and rear of said trains and to track the movement of trains on the network. Indentifying the front and rear of a train may involve identifying the start/end (302, 303) of a continuous acoustic signal generated by the train and/or identifying characteristic signatures generated by the wheelsets of the train. The method may be used to provide moving block signalling.
