ABSTRACT:
A method and computer program product of limiting sand use in a railroad locomotive sanding system applying sand to railroad rails to enhance adhesion of wheels of a railroad locomotive on a track having a pair of railroad rails, the sanding system including a plurality of sand applicators for each rail for directing sand flow toward the rail and with the locomotive having two trucks carrying the wheels for supporting and propelling the locomotive along the track. The method and computer program product may include steps of automatically controlling a flow of sand applied to the rail by the locomotive sanding system to limit the application of sand to situations in which applying sand to the rail would be effective to increase the adhesion of at least one of the railroad locomotive wheels on the rail by a predetermined incremental amount. The operation of each of the plurality of sand applicators may be independently controlled for selectively operating those sand applicators whose operation will result in at least the predetermined incremental increase in adhesion of the locomotive wheels on the rail, while not operating the other sand applicators so as to limit the amount of sand applied to the track.
