Abstract:
1. A device for lubricating a length of railroad track comprising application means for applying a quantity of lubricant to a portion of track forward of said length of railroad track, means for detecting train speed of a train passing over said length of railroad track, lubrication detection means for measuring a physical reaction that varies as a factor of train speed and track lubrication, a table relating train speed and measurements of said physical reaction indicative of a lubricated track, wherein measurements of said physical reaction vary as a function of train speed, means for comparing said physical reaction measurement from said lubrication detection means with said measurements indicative of a lubricated track for a train moving at said train speed, and means for energizing said application means to apply a quantity of lubricant to said portion of said track where said means for comparing determines that said physical reaction measurement falls out side of said measurements indicative of a lubricated track.
