Abstract
Systems and methods are disclosed for reliable detection of oncoming trains and for warning roadway personnel working on the railroad track of the oncoming train. A train detection system includes a wireless communication network further including train detection modules attached to catenary poles along the sides of the railroad track. Each train detection module is equipped with at least two diverse sensors configured to detect trains and other on-track vehicles. Each train detection sensor is simultaneously active and works with other train detection sensors to detect an approaching train and generate train alerts. The train alerts are transmitted wirelessly over the wireless communication network by the train detection modules. The system transmits train alerts to personal alert devices worn by roadway workers. The personal alert device forms an ad-hoc wireless network with the train detection modules.
