  • Patent number: 10173700
    Abstract: A top of rail (TOR) applicator has a bar positioned in a housing and an exit orifice on the upper portion of the bar for delivering a friction control composition to the crown of a railhead. The upper portion of the bar slopes away from the friction control composition exit orifice. The bar may be composed of an elastomer such as polyurethane. A passageway may extend from an inlet port to the exit orifice. The friction reduction composition is pumped into the inlet port, through the passageway to the exit orifice and then onto the crown of the railhead. The friction reduction composition may be thixotropic.
