JNR tried to develop a new style limited express.

Even when the Pacific War ended, the railroad of Japan did not stop.
And it was moving on time mostly. Of course, there were few trains in operation and there were no vacancies. Therefore, the limited express was not driven. Operation of the limited express was resumed in 1949. It was the limited express HEIWA. It means 'peaceable' in English. The name was changed into the limited express TSUBAME in 1950. You will understand how the limited express TSUBAME was loved by Japanese people on the railroad of Japan. The first-class observation car, the second-class wagon, the third class coach, and the dining car were connected with it. The EF58 type electric locomotive towed the electrified section. It towed the royal Train. The C62 type steam locomotive is famous also as a prototype of the Galaxy Express 999 of anime. It made the world record of the steam locomotive of a narrow gauge of 129 km/h. Moreover, the C62 led the express NISEKO of Hokkaido after that. It was an express which runs in the beautiful scenes of snowstorms. The whole line of the main Tokaido line was electrified in 1956. The Limited Express Tsubame ran from Tokyo Station to Osaka Station in 7 hours and 30 minutes. However, it was still a limited express with which an electric locomotive tows a coach. Here, JNR tried to develop a new style limited express. It was a limited express in an Electric Multiple-Unit.
