The Tōkaidō Shinkansen (Japanese: 東海道新幹線,とうかいどうしんかんせん) is a high speed railway line of Central Japan Railway Company (JR Central) in Japan. It is also the first high speed railway line in the world, and it marked the start of the Shinkansen technology.
There are three types of trains serving this route. When the Tōkaidō Shinkansen started operations in 1972, only Hikari and Kodama were serving this line. Among the two trains types, Kodama trains stop at all stations, while the Hikari trains skip some of the stations to make the travel shorter. In early 1990s, Nozomi was added to the service. Nozomi trains skips even more stations then the Hikari, which is now the fastest service on this route.
