0 Series Shinkansen
From Wikipedia, the free encyclopedia.
The 0 series (which were not originally so classed; there was no need to distinguish classes of trainset until later) entered service with the start of Tokaido Shinkansen operations in 1964. These units were white with a blue stripe along the windows and another at the bottom of the car body, including the front pilot. The story goes that the noses were styled after the Douglas DC-8 airliner, and certainly the resemblance is apparent.
Unlike previous Japanese trains, the Tokaido Shinkansen and all subsequent Shinkansen were standard gauge (4'8½", 1,435 mm between the rails). The trains are all powered by 25kV AC electricity at 60 Hz. On the 0 series, all axles of all cars are powered by 185 kW traction motors; this is sufficient for a 220 km/h (136 mph) top speed.
The original trains were 12-car sets; some subsequent sets were 16 car. Later, shorter trains of 6 cars and even 4 cars were assembled for lesser duties. Production of 0 series units continued from 1963 until 1986.
Existence as a Shinkansen train is tough; though most rail equipment has a service life of thirty or more years, Shinkansen sets are tired after fifteen, and they are generally removed from service after that point. All 0 series cars are now past fifteen years of service; therefore, few are left. The only 0 series sets now in use are 6 car sets used on JR West Kodama services between Shin-Osaka and Hakata, and on the Hakata Minami Line, which is technically not a Shinkansen line.
