Track Monitoring System

The Track Monitoring System is intended for monitoring settlement and twist of railroad tracks which may be affected by nearby construction activity, such as tunnelling or adjacent excavation, or which are located near hazardous zones such as potential washout or landslide areas.

Overview

The Track Monitoring System is intended for monitoring settlement and twist of railroad tracks which may be affected by nearby construction activity such as tunnelling or adjacent excavation, or locales near hazardous zones such as potential washout or landslide areas.

The Track Monitoring System consists of bussed settlement sensors mounted longitudinally along the track alignment, typically with a mount spacing of 2 or 3 meters and one, or several, track twist sensors mounted perpendicularly to the settlement sensors. The 2 or 3 meter lengths can be cut down in the field to fit the actual tie locations.

Settlement and twist sensors are based on the same MEMS devices used in RST’s MEMS Tilt & Inclination Series of products from RST Instruments. These sensors are fully compatible with RST’s flexDAQ Data Loggers and GeoViewer software for data display and management.

I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
