Summary Recently, there have been increasing requirements to control the rolling noise generated by the wheels and rails, but the conventional counter measures such as noise barriers have a big disadvantage in that their installations are very labor-intensive. Therefore, the authors have developed a new type of material, called rail noise isolating material (RNIM), which consists of two laminated layers, the inner one a foamed ethylene-—propylene rubber and the outer one vibration-damped steel. An impact test executed in a laboratory and some noise measurements executed on commercial lines have verified that RNIM is effective in reducing rolling noise.
