EL Track Monitoring System
Applications
Track monitoring systems help maintain the safety of railroad tracks by monitoring settlement and twist. The systems are installed when nearby construction activities, such as tunneling or excavation, may affect the safety of the tracks. The systems are also installed on tracks that cross potential washout and landslide areas.
Settlement of the track is monitored by linked EL tilt sensors that are mounted directly on the ties (sleepers). With continuous track, the linked sensors are anchored in the ballast. Twist in the track is monitored by tilt sensors mounted on the long-axis of the ties. All sensors are connected to an automatic data acquisition system, so that settlement and twist can be plotted in near-real time and trigger alarms if movements exceed safe limits.
Features
- Continuous, unattended monitoring with immediate processing of data.
- Two alarm thresholds for early warning of trouble.
- Shows the site in section view and plan view, so activity can be comprehended at a glance.
- Shows a real-time profile of the track and real-time settlement or elevation values at each sensor.
- Shows twist values for set lengths of track.
- Shows 5-day trend graphs for any sensor.
- Does not interfere with rail traffic, reballasting operations, or construction activities.
Track Monitoring systems have been installed in the US, UK,Canada, and Switzerland and have been tested and documented by third parties.
