The utility model provides a shock attenuation noise elimination rail, includes railhead, the web of the rail, the flange of rail and foaming bolster. The web of the rail is located between the institute's railhead and the flange of rail to the both ends difference fixed connection railhead and the flange of rail of the web of the rail. The both sides face of the web of the rail is pasted respectively and is connected the foaming bolster. Above -mentioned shock attenuation noise elimination rail is because both sides face at the web of the rail is pasted respectively and is connected with thefoaming bolster, and the foaming bolster has shock attenuation, sound absorption. So when the wheel of train was advanced on the rail, during the vibrations of production and noise can conduct the foaming bolster, the bolster that is foamed received, very big reduction the vibrations degree and the noise frequency of this rail. 种减震消声钢轨，包括轨头、轨腰、轨底以及发泡缓冲件。轨腰位于所轨头与轨底之间，并且轨腰的两端分别固定连接轨头与轨底。轨腰的两侧面分别粘贴连接发泡缓冲件。上述减震消声钢轨由于在轨腰的两侧面分别
