Although no single method is superior, rail friction reduction, energy savings, and improvements to curving can be achieved by using a variety of lubrication practices.
Historically, lubrication has been shown to increase wheel and rail life, reduce energy consumption of trains, reduce lateral curving loads, and control noise emissions. However, it has also been shown that too much, or improperly applied, lubrication may negatively affect truck curving, train handling, and rail fatigue.
To examine the pluses and minuses of various lubrication methods, Transportation Technology Center, Inc., has conducted several lubrication studies over the years. The results show that rail friction reduction, energy savings, and improvements to curving can be achieved by using a variety of lubrication practices.
Currently, the Association of American Railroads is sponsoring research by TTCI engineers that will recommend target friction levels that field personnel can use for adjusting lubrication. Last year, AAR's NUCARS computer simulation model evaluated lubrication methods and their effectiveness as influenced by variations in track curvature, wheel/rail profile pairings, truck conditions, and train speed. Modeling data was supplemented with data from on-track testing at the Transportation Technology Center, Pueblo, Colo. These data were analyzed to develop best practices for lubrication (rail-friction guidelines) and to evaluate top-of-rail (TOR) lubrication effectiveness. They show that an effective, consistent wheel/rail lubrication application method reduces many of the negative effects of wheel/rail forces.
