Heavy or long wheel-based vehicles can become stuck or â€œhigh-centeredâ€ on railroad grade crossings, sometimes leading to highly destructive train accidents. An emergency device that â€œtalksâ€ directly to the railroad traffic signaling infrastructure could send instant red stop signals to trains within several miles of a blocked crossing. Fermilab has developed a simple, inexpensive, effective device to reduce collision incidents related to vehicles stuck on railroad grade crossings. This device will simulate the continuity of locomotives or other rolling stock from rail to rail therefore closing the existing DC track circuit, mimicking the presence of a train at the location of deployment. The intention of the deployment of this device is to force adjoining railroad block signals into red condition indicating that a grade crossing is occupied in the event of a vehicle becoming stranded. Emergency use only device.
