Wheels equipped with rolling stock are essential apparatus in terms of safety, ride comfort, cost, and other relevant factors. Since the wheels are worn out and damaged due to daily runs railroad operators carry out wheel reprofiling to restore the wheel profile to the design profile, and are maintaining safety and ride comfort. However, for the wheel reprofiling, an additional cost will be unavoidable because the diameter of wheels reduced by the wheel reprofiling. It is an inevitable theme for railroad operators for cost-saving by adequate management of wheels. JR East replaced every wheel of entire passenger trains into modified are wheel profile by the end of September 2002. In conjunction with such movements, it was presumable that the wheel wear was also likely to vary: we investigated the wear tendency anew and decided to acquire knowledge when proposing the wheel management suitable for the modified are wheel profile. Consequently, the wheels using sintered metal brake shoes tend to cause concave wears. however, not causing any adverse effect to carbody vibration and curving performance improves conversely showed that it was effective in reducing flange wears.
