Abstract (en)
[origin: GB2593767A] A device 1 for monitoring the condition of the surface of railway track rails 2, comprises a spectrometer configured to monitor at least one frequency corresponding that indicates the presence of a contaminant on a railway track rail and to provides an output indicative of the presence or absence of the contaminant on a railway track rail 2. The spectrometer may monitor a plurality of frequencies, and/or be a Ramen spectrometer. The device may be handheld, or mounted alongside a track, potentially for monitoring a plurality of rails. A surface conditioning device may act in response to data received from the monitoring device. The surface conditioning may be by a plasma delivered to the rail.
