Individual Components

Local Radio Warning System (LRW)

The LRW serves as both the command center and communications suite for all sensors integrated into the STS system. An interface board allows operators in the field to easily program basic parameters of operation for the suite. Emergency signals are broadcast over a 5-mile radius in the case of sensor activation.

Derailment Sensor (DRS)

A Metrom Rail DRS is designed to detect local wheel derailments by fracturing under the weight of a misaligned wheel. The fracture will open an electrical circuit which is interpreted by the LRW.

Track Integrity Sensor (TIS)

The TIS is a sensor secured to both the rail and an embedded ballast probe. In the case of rail deformation or ballast washout, the sensor will immediately send an alarm activation to the LRW for broadcast. The TIS ensures that sensitive locations, such as bridges, can be monitored at all times. Available in Q1 2013.
