The noise of narrow-gauge lines is composed of rolling noise and driving system noise. In recent years, measures are required to prevent the ever-increasing rolling noise of railway vehicles due to speedup, in addition to those against the noise emitted from electric apparatus and the driving system. This paper reports the characteristics of wheel vibration sound obtained from running and bench experiments of wheels with different web shapes, or webs of corrugated and straight standard types, which are used for narrow-gauge railway vehicles.
