Abstract
A railroad friction-modification system for applying a friction modifier to a section of railroad track, the system comprising an external storage tank for storing the friction modifier, a railroad friction-modification assembly for applying the friction modifier, a tube for connecting the external storage tank to the railroad friction-modification assembly, and a mounting assembly for securing the railroad friction-modification assembly to the rail. The railroad friction-modification assembly includes an expandable membrane for storing the friction modifier, an inlet valve for receiving the friction modifier from the external storage tank, a housing for securely containing the expandable membrane, at least one outlet valve for expelling the friction modifier from the expandable membrane upon the application of a force, and a nozzle for directing the expelled friction modifier onto the section of railroad track. The force is applied by the wheel of a railroad car, such that the railroad friction-modification assembly pumps the friction modifier in a peristaltic action.
