The N700 series (N700系) is a Japanese Shinkansen high-speed train with tilting capability developed jointly by JR Central and JR West for use on the Tōkaidō and Sanyō Shinkansen lines.
N700 series trains have a maximum speed of 300 km/h (186 mph), and tilting of up to one degree allows the trains to maintain 270 km/h even on 2,500 m radius curves that previously had a maximum speed of 255 km/h. Another feature of the N700 is that it accelerates quicker than other shinkansen trains, with an acceleration rate of 2.6 km/h/s. This enables it to reach 270 km/h in only three minutes. Because of these improvements, trains can travel between Tokyo and Osaka on a Nozomi run in as little as 2 hours and 25 minutes (5 minutes faster than before).
N700 series trains are presently replacing 300, 500 and 700 series-operated Nozomi runs on a regular basis. By the end of February 2009, the N700 will be responsible for 74 Nozomi services per day.[3]
All Nozomi through runs (over the full route between Tokyo and Hakata) are scheduled to use the N700 exclusively by 2009. By 2011, all regularly-scheduled Nozomi services, including runs limited only to the Tokaido Shinkansen, will be operated by the N700.[4]
The N700 is also used on select Hikari services during the day, as well as some early-morning and late-night Kodama runs between Tokyo and Mishima/Hamamatsu.

[edit] Variants
[edit] 16-car Z sets
The prototype 16-car train (Z0) was delivered in March 2005 for extensive testing and endurance running. Cars 1 to 4 were built by Hitachi Ltd., cars 5 to 14 were built by Nippon Sharyo, and cars 15 and 16 were built by Kawasaki Heavy Industries.[5]
The first full-production Z set (Z1) was delivered to JR Central in April 2007, and trains entered revenue service on 1 July 2007, with eight daily Nozomi service runs.
The prototype set Z0 remains as a JR Central test train with cars numbered in the -9000 series, and is not used in revenue service.

[edit] 16-car N sets (N700-3000 series)
The 16-car N sets are operated by JR West on Tōkaidō and Sanyō Shinkansen services. The first set, N1, was delivered in June 2007, entering service on 1 July 2007.[5]
[edit] 8-car S sets (N700-7000 series)
The N700-7000 series variant are 8-car sets on order by JR West and JR Kyushu for use on through-running Sakura services between Shin-Osaka and Kagoshima-Chūō on the Kyushu Shinkansen from spring 2011.[6] The first set (S1) was delivered to Hakata Depot in October 2008. These trains do not feature the tilting mechanism of the earlier N700 trains.[7]
External livery is shiraai (白藍?) pale blue intended to evoke the colour of traditional porcelain with indigo and gold bodyside lining.[6]
[edit] Interior
These sets feature a Green car saloon in half of one car (car 6) consisting of 24 seats (6 rows) arranged in 2+2 abreast configuration with 480 mm wide seats and a seat pitch of 1,160 mm. Cars 4 to 8 (including half of car 6) are designated as "reserved seating" cars with 2+2 abreast configuration, 465 mm wide seats and a seat pitch of 1,040 mm. Cars 1 to 3 are "non-reserved seating" cars with 2+3 abreast configuration, 440 mm wide seats (460 mm in middle of 3-seat row) and a seat pitch of 1,040 mm.[6]
[edit] N700-I Bullet
This is a proposed export version of the N700 series design announced by JR Central Chairman Yoshiyuki Kasai at an international high-speed railway symposium held in Nagoya on 16 November 2009.[8] Nominally specified as an 8-car set with a maximum operating speed of 330 km/h, the train can be configured in lengths from 6 to 15 cars to suit customer requirements.[9]
[edit] High-speed trials
On 16 November 2009, JR Central conducted a late-night high-speed demonstration run using N700 series trainset Z0, recording a maximum speed of 332 km/h on the Tōkaidō Shinkansen between Maibara and Kyoto. The high-speed run was conducted as a demonstration for approximately 160 international guests attending a high-speed railway symposium in Nagoya.[10][11]
