Description

This information is requested as part of a soft market testing exercise in order to seek the market's solution to detect lateral movement at any point in the track over a 100m length, including in curves and in turnout routes in S&C. The two scenarios in mind are to detect gauge spread in S&C turnouts and to detect the presence of a track buckle. The solution ideally will: 1. Be portable to enable management of various sites based on engineering need 2. Transmit alerts to Engineers - positive confirmation at a suitable interval that the track hasn't moved but an alarm when the track is showing signs of irregular or sudden movement 3. Withstand the operating environment - vibrations, minor track movement and weather 4. Have battery life sufficient to give engineers coverage on a site for up to 7 days 5. Must measure and record dynamic lateral movements of the rail foot under traffic relative to a datum 6 Must be compatible with DC third rail electrification and train detection systems 7 Must be able to detect complete fracture of housing or chairscrew at or below the top surface of the bearer without removal of the associated rail fastening 8 Device must work for housings and chairscrews in concrete and timber bearers. 9 Must be compatible with DC third rail electrification
