ABSTRACT: This report documents the testing of a top of the rail lubricant applied in computer-controlled quantities. This system, the SENTRAEN 2000™, was developed by Tranergy. The testing was carried out over CSXT operated track between Corbin, KY and Cartersville, GA on various train runs from February 15, 1999 to March 4, 1999. These tests, sponsored by FRA, DOE, and CSXT, were conducted to assess the use of the top of rail lubrication system in normal operating conditions. The report describes the test criteria used to evaluate the performance of the top of the rail lubricating system, the instrumentation used, the test locations, and the track conditions. Results are presented from tests conducted on CSXT’s Stilesboro’s 90 car coal trains. The significance of the results is discussed. Conclusions and recommendations are presented.
