Abstract
A tube and tube retainer applied to the base of a railroad rail and capable of being simply and quickly adjusted for the application of lubricant to the wheel/rail interface contact patch. The tube accepts a lubricant supply from an external source at one end and directs it to the appropriate area of the wheel/rail contact patch. Implementation may include a plurality of such tubes on one or both rails to improve effectiveness. The present invention reduces overall waste by applying smaller amounts of lubricant with each tube, but increasing the total amount of lubricant applied.
