Paper Abstract

The measurement of lateral track parameters, using contacting sensors, from a high-speed rail vehicle presents problems due to the vulnerability of mechanical probes and feelers. To overcome these problems a non-contacting system based on commercially available solid-state scanners has been developed by British Railways. The sensor equipment consists of two separate linescan cameras mounted vertically above each rail. The rails are obliquely illuminated from projectors mounted on the bogie (truck), and it is possible by processing the camera video signals to detect -that part of the scan corresponding to the gauge face of each rai1. This information can then be used to calculate track gauge, and, in conjunction with other equipment, track alignment.
