The 300 series (300系) was a Japanese high-speed Shinkansen train type which operated on the Tokaido and Sanyo Shinkansen lines in Japan between 1992 and 2012. When first introduced, they were used on the fastest Nozomi services, being capable of 270 km/h (170 mph). As more were delivered (66 trains by 1998) they replaced earlier units on Hikari service and allowed the thus displaced 100 series units to finally in turn displace 0 series units on almost all services.

With the introduction of newer 700 series and N700 series equipment, the 300 series sets were gradually demoted to slower Hikari and Kodama services, and were completely withdrawn from Tokaido and Sanyo Shinkansen services by the start of the revised timetable on 17 March 2012.

Design

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

Prototype set J1 near Hamamatsu Station on a test run, April 2003

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 Maibara and Kyoto, 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

JR Central set J61, February 2011

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.

In December 1998, set J59 was fitted experimentally with new 700 series style single-arm pantographs and fairings to reduce noise and air resistance. Following testing, JR Central subsequently fitted new pantographs to all of its sets, with modifications completed by late 2002.

In October 2004, JR Central announced plans for ride improvement modifications to its 300 series fleet involving the addition of semi-active vibration control units to seven cars out of the total of sixteen in each set (end cars 1 and 16, pantograph cars 6 and 12, and Green cars 8 to 10), and also new non-linear air suspension on all cars in each set. The new secondary suspension offered firmer support against lateral movement. The entire fleet operated by JR Central received the modifications by February 2007.

With the entry into service of new N700 series trains, withdrawals of production 300 series sets began in July 2007 with the withdrawal of set J14.

The remaining fleet of JR Central 300 series sets were removed from regular scheduled services from 1 February 2012, and were completely withdrawn following the final runs on 16 March 2012.
