Rail track displacement measurement system and proactive maintenance approach

摘要

A monitoring and warning system is provided that measures a track displacement as an indication of an operational condition of railway tracks and a rail track structure. The system comprises a sensor and a device coupled to the sensor. In response to a physical measurement of a vertical displacement of a railway track in a down direction by the sensor, the device is configured to provide a warning signal indicative of a possible future failure of the railway track or the rail track structure for proactive track maintenance purposes.
