Abstract: An improved method and apparatus for determining the amount of lubricant dispensed to a rail, adjusting the amount of available lubricant for dispensing based on the amount of lubricant remaining, and advising the operator of same. The apparatus includes a reservoir of lubricant suspended from a load beam having load cells communicating with a microprocessor and a controller to determine the amount of lubricant remaining within the reservoir on a real-time basis as lubricant is dispersed. The method includes the determination of the amount of lubricant remaining and, following dispensing additional lubricant, re-determining the amount of lubricant remaining. In this manner, an operator may prepare a schedule for replenishment of the reservoirs of various lubricating stations based on feedback of the remaining amount of lubricant remaining. Thus, an operator may predict track downtime for refilling of a plurality of lubricating stations and schedule such to minimized track downtime.

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 orifices. The bar may be composed of an elastomer such as polyurethane. Passageway extend from an inlet or entry orifice to the exit orifices. The friction reduction composition is pumped into the entry orifice, through the passageways to the exit orifices and then onto the crown of the railhead. The friction reduction composition may be thixotropic.

Abstract: A friction control composition having high and positive frictional properties for sliding steel surfaces includes a water insoluble hydrocarbon that enables a reduced water content, a rheological additive, a freezing point depressant, a friction modifier, and a lubricant.
