A mobile unit positionable and drivable upon railroad tracks for applying a bead of lubricant to the gauge surfaces of the track which includes a lubricant delivery source for delivering lubricant to a pair of nozzles which are arranged in position to direct the lubricant onto the proper area of the track. The unit includes an electric/hydraulic power unit to supply pumping power to a primary lubricant delivery unit which directs the lubricant through a common flow system to the nozzles which are directed to the proper rail locations. The unit also includes lubricant filters, automatic shut off devices and automatic speed control devices for proper delivery of the lubricant to the rail surface. Heating devices are included for temperature maintenance of the lubricant under various temperature conditions.
