Abstract

A system for reliable detection of an approaching train and warning the roadway workers in proximity of the track is described. The system comprises at least one train detector cone (TDC) deployed along a side of an active railroad track and one or more personnel warning cones (PWC) placed near the work site, the cones configured in a wireless mesh network to provide redundant communication links. Detection of a train by the train detector cone is transmitted to the personnel warning cones which provide audible and visual warnings to nearby roadway workers. The system also includes a remote server for centralized tracking and monitoring of the train detector cones and personnel warning cones.
