Rail Curve Grease Evaluation – Part 2

This is the second in a series of four articles that offers a summary of a comprehensive study of the performance of biobased and conventional railroad curve grease. The intent of this study was to investigate the feasibility of using readily biodegradable lubricants and greases in locomotive, rolling stock and other equipment. The research results indicated that bio-based greases perform equal and in some cases more effectively for friction mitigation on railroad tracks.

The university of Northern Iowa, National Ag-Based lubricant (UNI-NABL) Center performed the research on behalf of the United States Federal Railroad Administration (FRA), and the activities were divided into three categories: (1) Laboratory Testing, (2) Testing in wayside equipment in temperature controlled environmental chamber, (3) Field testing of lubricants in wayside equipment in a revenue service railroad.
