Abstract: Methods and systems for real-time detection and reporting of trains is described. A system includes two train detection units (TDUs) for each railroad track intersecting a municipality boundary. Each TDU including a proximity sensor to sense a presence of an object on the railroad track, a camera to capture an image of a detected object when the object is within a detection zone, a radar to measure speed when the detected object is classified as a train, and a processor to classify the detected object, generate a timestamp corresponding to when the train entered and exited the detection zone, and determine a train length from the speed and time delta between entrance timestamp and exit timestamp. A train detection controller to receive at least the train length and a TDU identification from one of the two TDUs, and determine estimated time of arrivals for the train at different municipality locations.
