The Protracker Roadway Worker Protection System includes the Train Mounted Unit, Flagger, Personal Alert Device (PAD), and Portable Warning Horn & Light (PWLH). The system is designed to be mounted in the cab of a train or tied into the train’s monitor. The Protracker will automtically signal the track workers that a train is approaching. Once a train is in range, the PADs and PWLHs will signal that a train is approaching. This system enhances the secondary safety for work crews and train operators.
