Portable Lateral movement detection to detect S&C gauge spread - EARLY MARKET ENGAGEMENT

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 suit...
