Abstract: In this paper detecting the faults in the railway infrastructure with the help of wireless sensor networks can be achieved. Nowadays Sensor technology can be used widely and the sensor devices have become cheaper. Wireless communication such as GSM-R, Satellite, GPRS is used for transmitting and receiving the signals. Railway infrastructure includes tracks, bogies, wheels can be monitored through condition monitoring. Defects can be identified using acoustic emission sensor and PIR sensor. Acoustic emission sensor is used for detecting the cracks on the tracks and PIR sensor is used for detecting the presence of human and animals on the track. Automated monitoring achieves accuracy of the fault and has a less cost, low power consumption and less analysis time. The exact location of the fault can be identified by the sensors without any human inspection so that people time can be saved.
