300 Series Shinkansen

The front-end styling of these units consisted of a 'curved wedge', replacing the aircraft-style nose-cones of previous Shinkansen trains. The furthest forward point was the very bottom of the pilot. They were painted brilliant white with a medium-thick blue stripe beneath the windows. They were only formed as sixteen-car sets and had no restaurant cars, though they did originally feature two refreshment counters (later removed). Technically, they are notable for being the first Shinkansen sets to employ three-phase AC traction motors instead of direct current units, as well as new bolsterless bogies to reduce weight. The 300 series was awarded the Laurel Prize in May 1993. ==Variants==

• 300-9000 series: 16-car pre-series set • 300-0 series: 16-car "J" sets owned by JR Central, introduced from March 1992 • 300-3000 series: 16-car "F" sets owned by JR-West ==Pre-series 300-9000 series set==

The pre-series unit, J0, numbered in the 300-9000 series, was delivered on 8 March 1990, and underwent extensive testing and endurance running before the start of the new Nozomi services in March 1992. In the early hours of 1 March 1991, this set recorded a speed of 325.7 km/h on the Tōkaidō Shinkansen between and , a Japanese national speed record at the time. The set was modified to production standards in March 1993, becoming set "J1", but it differed from the production units in a number of ways. Visually, the driving cab had a different windscreen design, different headlight arrangement, and flared side panels over the front bogies. The prototype set was initially fitted with five pantographs, but this was later reduced to two in line with modifications to the production fleet. Limited water tank capacity meant that the unit was not capable of running return trips from Tokyo to Hakata, and was normally restricted to Tokyo to Osaka/Okayama/Hiroshima workings. From 2001 onwards, this unit was converted for use as a JR Central test train for testing new digital ATC equipment on the Tokaido Shinkansen. It was finally withdrawn in March 2007. All cars except one end car, 322-9001, were cut up. ==JR Central J sets==

60 16-car sets (excluding pre-series set J1) operated by Central Japan Railway Company (JR Central). These sets were delivered between February 1992 and October 1998. and were completely withdrawn following the final runs on 16 March 2012. Cars 6 and 12 each had one single-arm pantograph.

These were 16-car 300 series sets operated by West Japan Railway Company (JR-West). A total of nine sets were delivered between December 1992 and September 1993. The last remaining sets were withdrawn by spring 2012 and replaced by eight 700 series "C" sets transferred from JR Central. Formation The 16-car F sets were formed as follows, with car 1 at the Hakata end. Cars 6 and 12 each had one single-arm pantograph.
