A network of monitoring devices 1 for monitoring the condition of the surface of railway track rails 2, each of the monitoring devices 1 comprising a spectrometer 3 configured to monitor at least one frequency that indicates the presence of a contaminant on a railway track rail 2 and to provide an output indicative of the presence or absence of the contaminant on a railway track rail 2, and each of the monitoring devices 1 comprising a transmitter 19 arranged to transmit its output to a central database 20. The central database 20 is configured to store data from the monitoring devices 1 over time, thereby to establish historical data of track conditions as monitored by the monitoring devices 1. A comparator 22 is configured to compare current track conditions over the network with historical track conditions over the network, thereby to provide an indication of likely developments of track conditions.
