A positive train control unit 100 for a track way 60 or track way crossing comprises a plurality of different sensors 110, 312 coupled to a processor 120 that determines whether there is an object on the track way 60 and/or the track way crossing, and/or an anomaly of the track way 60, and if there is, provides an alert. The plural sensors 110, 312 may include a visual imager 112, 3112, an infrared imager 114, 3114, a radar 116, 3116, a doppler radar 116, 3116, a laser sensor 118, 3118, a laser ranging device 118, 3118, an acoustic sensor 122, 3122, and/or an acoustic ranging device 122, 3122. Data from the plural sensors 110, 312 is geo-tagged and time tagged. Some embodiments of the train control 100 employ track monitors 330, switch monitors 320 and/or wayside monitors 310, and some employ locating devices 130 such as GPS 132, 3132 and inertial devices 134.
