This paper illustrates the present performance of North American freight car wheels on an industry basis. It indicates areas where attention must be directed. Thin flange is found the predominant cause for wheelset removal and wheel/tread wear is the major cause of accidents. To reduce flange wear and improve service life, the following are recommended: Increased use of heat-treated wheels; application of constant-contact side bearings to minimize truck hunting; use of high-speed trucks; introduction of steering type trucks.
