ABSTRACT:
A system is provided for determining whether a railway car passing a sensing station is a freight car. The system utilizes wheel trips along the track at the sensing station to determine the spacing between axles of the car. If the spacing between axles is determined to fall between slightly more than 4' - 5" to slightly less than 6' - 1" the car is presumed to be a freight car.
