abstract

The recent appearance of vertical split rim (VSR) wheel failures has presented North American railroads with a new mode of wheel failure. These failures originate from tread shelling as a result of rolling contact fatigue (RCF). One or more of the shallow RCF cracks initiate a brittle fracture that causes the separation of a large portion of the front or back of the wheel rim as shown in Figures 1, 2, and 3. TTCI is leading a consortium made up of railroads, suppliers, car owners, and the Federal Railroad Administration (FRA) to investigate wheel defects. VSR research is at the forefront of that effort.
