  • Description:
    This 1955 committee report examines the engineering and economic case for curve lubrication on North American railroads, with emphasis on track-mounted lubricators. The report identifies gauge-face wear of high rails and wheel-flange wear as major maintenance concerns that became more significant with diesel locomotives, higher speeds, and four-wheel truck steering characteristics. Drawing on experience from representatives of 22 railroads, the committee reports that proper lubrication can substantially reduce abrasion and extend high-rail life by approximately 25 to 300 percent, depending on curvature, speed, tonnage, superelevation, and other operating conditions. Its economic analysis is primarily a Maintenance-of-Way assessment, emphasizing longer rail and track-component life, reduced re-gauging and rail replacement, and lower labor and material costs; in some cases, rail savings alone were considered sufficient to recover lubricator costs within the first year. Mechanical benefits, including reduced locomotive and car-wheel wear, are acknowledged but not systematically quantified. The report also notes that lubrication reduces friction in curves and can increase trailing-tonnage capability on grades with heavy curvature, but it provides no quantitative estimates of resistance reduction, tonnage gains, fuel savings, or other Transportation benefits. The study therefore represents a partial economic assessment centered on wear reduction and asset-life extension, with additional Mechanical and Transportation benefits largely left unquantified. It also provides practical guidance on lubricator selection, placement, inspection, lubricant characteristics, and maintenance.
