The impact noise at rail joints generated due to a wheel passing is one of the main elements of the rail rolling noise. Therefore, a countermeasure effective against noise mitigation and easy to install is requested. A new countermeasure material against the impact noise at rail joints that is named "Noise Insulating Material for Rail Joint" has been prototyped. This prototype consists of two layers. One layer on the inside is a sound absorbing material that is composed of bounded inorganic particles, and the other layer on the outside is a sound insulating material that is sound insulating plate such as plastic. As the results of impact tests and track motorcar tests executed at the rail joints in Hino civil engineering testing station, it has been revealed that the prototype is effective for reducing the noise radiated from the rail joints.
