International Activities

RTRI aims at contributing to the development of railway technologies around the world by introducing its R&D results to other countries and carrying out joint researches with overseas research organizations.


To introduce its R&D results, RTRI publishes

Quarterly Report of RTRI (QR)

technical journal in English


timely release of the latest information to the world

Support of International Conferences

WCRR is the world’s largest international congress on railway research which provides opportunities that railway researchers and engineers are able to gather with managers and executives of railway operators in one congress. It was started in 1994 for the purpose of providing an overview of the world’s development of railway technologies and discussing future directions to be taken by railway operators.

RTRI is one of the founding members of the WCRR Organizing Committee with AAR (Association of American Railroads, USA), TTCI (Transportation Technology Center, Inc., USA), Trenitalia (Italian Railways, Italy), DB (German Railways, Germany), SNCF (French National Railways, France), UIC (International Union of Railways, France) and RSSB (Railway Safety and Standards Board, UK).

The IWRN is a workshop specialized to the issues of railway noise and vibration. Since 1976, thirteen workshops have been held and contributed to building a scientific foundation for reducing environmental impact by air-borne, ground-borne and structure-borne noise and vibration.
RTRI has continuously supported the workshops. In 2010, RTRI hosted its 10th workshop which was held in Nagahama, Japan.

UIC World Congress on High-Speed Rail provides an opportunity to exchange experience and obtain an overview on all aspects of the future development of high-speed rail systems. The congress covers topics of new advances in technology and operating methods, commercial strategies and new service types, financing, environmental constraints, etc. The event includes a trade show and technical visits to various railway sites. This congress was started in 1992 as Eurailspeed and the congress name was changed to High-Speed Rail in 2010.


InnoTrans is a leading international trade fair for transport technology and takes places every two years in Berlin. This trade show consists of several segments: railway technology, railway infrastructure, public transport, interiors and tunnel construction, etc.
RTRI has been participating in this show, by joining the exhibition space organized by the Japan Overseas Railway System Association and presenting the state-of-the-art research results as well as practical technologies that will directly serve for commercial train operation overseas.
