ROYAL LUBE R.R. CURVE GREASE, is a soft, smooth calcium soap grease containing 12% graphite, as a filler.  In railway service, ROYAL LUBE R.R. CURVE GREASE, finds extensive use in trackside lubricators, as a curved rail lubricant.  Small quantities are applied periodically to the inside railhead on sharp curves, where it prevents direct metal-to-metal contact between the rail, and wheel flange, and reduces the severe wear which would otherwise result.   Because of the extreme pressures generated between the wheel flanges, and rails as heavy trains negotiate sharp curves, the base grease acts mostly as a carrier for the graphite.  ROYAL LUBE R.R. CURVE GREASE, is formulated for excellent carry on long curves.
