Track-Watch® Safety System Operation

Track-Watch® uses Train-Detectors placed at track locations that are a safe distance away from the track-working area. Train-Detectors sense oncoming rail traffic that triggers a transmitting “Alert” signal back to the track-working area. The track-working area has the Track Side Warning Alarm unit and the track-worker-worn TPASS®3 or SuperCELL® SC500, all which sound an audible and visual alert notifying the work crew that rail traffic is approaching.

(1) Rail traffic detected at a distance from the work site

Track-Watch® Train Detector senses rail traffic and transmits a secure, encrypted radio-frequency (RF) signal when a locomotive or other rail traffic is detected.

(2) RF warning signals are transmitted back to the work site

The RF transmitted warning signal is propagated through a MicroRepeater to the Track-Side Warning Alarm and the worker-worn TPASS®3 and SuperCELL® SC500 alerting track worker personnel of oncoming rail traffic.

(3) Warning signals are received at work site alerting track-worker personnel
