N700S Series Shinkansen
The N700S series (N700S系, Enu nana-hyaku esu-kei) is a Japanese Shinkansen high-speed train with tilting capability operated by JR Central and JR West on the Tokaido and San'yō Shinkansen lines since 2020, and JR Kyushu on the Nishi Kyushu Shinkansen line since 2022.
In June 2016, JR Central announced plans to build a new prototype "N700S" 16-car trainset (with "S" standing for "Supreme") for evaluating new technology and features on the Tokaido and Sanyo Shinkansen lines from March 2018.
Developed from the earlier N700 Series design, the N700S trains incorporate a number of new features. Refinements to the ATC and braking systems enable shorter braking distances in emergencies such as earthquakes. The traction system uses silicon carbide components, and uses 7% less power than the N700A series. Toshiba SCiB LTO batteries are installed so that the train can operate at low speed in the event of a disruption to overhead power, as well as keep toilets in operation.
Optimized underfloor equipment layout allows the same standard design to be used to easily produce 12, 8 and 6-car trainsets in addition to the Tokaido Shinkansen 16-car trainsets. This optimization was intended to make the train more flexible for possible export.
Green cars use active suspension to further improve ride quality, and ordinary-class cars have AC power outlets for each seat. Other features include larger luggage storage, closed-circuit television and "softer, more relaxing" interior lighting. In 2021, the train was awarded the Laurel Prize by the Japan Railfan Club.
In an announcement by JR Central, JR West, and JR Kyushu made on 17 October 2023, the companies stated that all onboard smoking rooms on the Tokaido, San'yo, and Kyushu Shinkansen lines would be abolished by Q2 2024.
A 16-car prototype set (J0), assembled at the Nippon Sharyo Toyokawa plant, was unveiled at JR Central's Hamamatsu depot on 10 March 2018. From 20 March, this set was used for testing and evaluation. High-speed trials at the design speed of 360 km/h (224 mph) were conducted during 2019 on the Tokaido Shinkansen, reaching a maximum speed of 363 km/h (226 mph). This is 28 km/h (17 mph) faster than the fastest speed ever achieved by the N700A, and may indicate plans to raise the maximum operating speed on the line.
The first full-production J set (J1) was delivered to JR Central in April 2020, with trains entering revenue service on 1 July 2020.
