ABSTRACT: The objective of the project was to study the efficacy of using bio-based lubricant and grease technologies in railroad applications (locomotives and maintenance of way equipment). Several commercially available rail curve greases were identified and tested. Three mineral oil-based and three bio-based rail curve greases were selected for comparative testing. Greases included a summer and a winter version. Testing was conducted in an environmental chamber using two grease dispensers from two Original Equipment Manufacturers (OEMs) at different temperatures. Field testing was conducted at two different sites on a revenue service railroad.
