Performance of Improved Rail Steels Under Heavy-axle-loads at FAST

This articles discusses how the extension of rail life has improved over the years in both hardness and micro-cleanliness, which has resulted in a decrease in track failures. However, for North American freight railroads, rolling contact fatigue (RCF) continues to be an issue. Because of this issue, the Transportation Technology Center, Incorporated (TTCI) is evaluating premium and intermediate strength rail steels at the Facility for Accelerated Service Testing (FAST) in a heavy-axle-load environment. This article summarizes the results from the latest round of testing at FAST. The data presented includes a discussion on the effects of lubrication, statistical analysis of real wear differences, analysis of deep seating shelling (DSS) defects and the analysis of cementite content in rail steel as it relates to RCF in railroad tracks.
