A method of determining when a first train has cleared an intersection a distance to permit travel of a second train through the intersection without risk of collision or contact includes: (a) sampling first GPS data corresponding to a location of a lead vehicle of the first train travelling on a first track when the lead vehicle passes proximate a marker; (b) sampling second GPS data corresponding to a location of a last vehicle of the first train moving on the first track; (c) comparing the second GPS data and the first GPS data: (d) repeating steps (b)-(c) until the location corresponding to the first GPS data and the location corresponding to the second GPS data are within a predetermined distance of each other, and (e) generating a signal when the locations are within the predetermined distance.
