This document describes the results of an investigation into the cause of premature cracking on 28-inch reversed dish transit car wheels. Methods used in determining the operating thermal and track load stresses in the critical areas of a wheel are presented. The observations made on the cracked specimens all indicate that the cracks which formed were due to fatigue. The problem was resolved by specifying a new wheel plate thickness and also by machining and shot peening the plate surface.
