Railway Technical Research Institute (鉄道総合技術研究所, Tetsudō Sōgō Gijutsu Kenkyūsho), or RTRI (鉄道総研, Tetsudō Sōken), is the technical research company under the Japan Railways group of companies.
RTRI was established in its current form in 1986 just before Japanese National Railways (JNR) was privatised and split into separate JR group companies. It conducts research on everything related to trains, railways and their operation. It is funded by the government and private rail companies. It works both on developing new railway technology, such as magnetic levitation, and on improving the safety and economy of current technology.
Its research areas include earthquake detection and alarm systems, obstacle detection on level crossings, improving adhesion between train wheels and tracks, reducing energy usage, noise barriers and preventing vibrations.
RTRI is the main developer in the Japanese SCMaglev program.
The RTRI is developing a variable gauge system, called the "Gauge Change Train", to allow 1,435 mm (4 ft 8 1⁄2 in) Shinkansen trains to access 1,067 mm (3 ft 6 in) lines of the original rail network.
The Shinkansen, colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is operated by five Japan Railways Group companies.
The Tokyo Metro Ginza Line is a subway line in Tokyo, Japan, operated by Tokyo Metro. The official name is Line 3 Ginza Line. It is 14.3 km long and serves the wards of Shibuya, Minato, Chūō, Chiyoda, and Taitō. It is the oldest subway line in Asia.

Its railway system is the largest in Japan, excluding Japan Railways Group. The railway network connects Osaka, Nara, Kyoto, Nagoya, Tsu, Ise, and Yoshino. Kintetsu Railway Co. Ltd. is a wholly owned subsidiary of Kintetsu Group Holdings Co., Ltd.
The Tobu Urban Park Line, formally known as the Tobu Noda Line, is a 62.7 km (39.0 mi) long railway line in Saitama and Chiba Prefectures operated by the Japanese private railway company Tobu Railway. It connects the satellite cities of Tokyo, such as Saitama, Kasukabe, Noda, Nagareyama, Matsudo, Kamagaya, Kashiwa, and Funabashi.
The Sōbu Main Line is a Japanese railway line operated by the East Japan Railway Company in Japan. It connects Tokyo with the east coast of Chiba Prefecture, passing through the cities of Funabashi, Chiba, and Chōshi. Its name derives from the old provinces of the area which it serves: Musashi (武蔵国), Shimōsa (下総国) and Kazusa (上総国). Its official line color is yellow.
Rail transport in Japan is a major means of passenger transport, especially for mass and high-speed travel between major cities and for commuter transport in urban areas. It is used relatively little for freight transport, accounting for just 0.84% of goods movement. The privatised network is highly efficient, requiring few subsidies and running extremely punctually.
Keifuku Electric Railroad Co., Ltd. is a railroad company based in Kyoto Prefecture, Japan in operation since March 2, 1942. It is a parent company of Keifuku Bus and Kyoto Bus, and an affiliated company of Keihan Electric Railway, which owns 42.89% of the company stock.

The Gauge Change Train(GCT) or Free Gauge Train is the name given to a Japanese project started in 1994 to develop a high-speed train with variable gauge axles to allow inter-running between the 1,435 mmstandard gauge Shinkansen network, and the 1,067 mm narrow gauge regional rail network.
The Izuhakone Railway Sunzu Line is a commuter railway line of the Izuhakone Railway, a private railroad in Japan. The line connects Mishima Station in the city of Mishima with Shuzenji Station in the city of Izu, both within Shizuoka Prefecture.
