# 700 Series Shinkansen

The **700 Series Shinkansen** (新幹線700系電車) is a Japanese high-speed train type jointly developed by Central Japan Railway Company ([JR Central](https://www.edgepedia.org/jr-central)) and West Japan Railway Company (JR West), placed in commercial operation on the Tokaido and Sanyo Shinkansen in March 1999 as the successor to the Series 300.<sup>[1](https://global.jr-central.co.jp/en/company/about/history.html)</sup><sup> • </sup><sup>[2](https://journals.sagepub.com/doi/10.1243/0954409001531261)</sup><sup> • </sup><sup>[3](https://jr-central.co.jp/news/release/nws001330.html)</sup>

## Design purpose

The design brief was balanced rather than record-chasing. Unlike the 500 series, a record-chasing design that JR West had brought out in 1997, the 700 series was intended to boost overall speeds on the Tokaido and Sanyo Shinkansen and to deliver a smoother, quieter ride than its predecessor, the 300 series—a train whose weight-reduced body had been pushed too far, resulting in noise and vibration—all without driving up construction or upkeep expenses.<sup>[7](https://japanrailatlas.com/rolling-stock/series-700)</sup>

Development was announced in 1996, and the type was initially designated "N300 series".<sup>[8](https://japanrailatlas.com/ja/rolling-stock/series-700)</sup> The design integrated technology acquired from the 300X experimental train, with which JR Central had begun test running in January 1995 and which set a [Shinkansen](https://www.edgepedia.org/shinkansen) speed record of 443 km/h in July 1996.<sup>[9](https://www.ejrcf.or.jp/jrtr/jrtr64/pdf/18-27_web.pdf)</sup><sup> • </sup><sup>[5](https://www.railjournal.com/in_depth/shinkansen-half-a-century-of-speed/)</sup>

## Aerodynamics

**Aerodynamic refinement was the type's defining engineering work.** The Series 700 concentrated improvements on the nose shape, the area around the carbody, the car coupling areas, the pantograph, and the pantograph cover.<sup>[2](https://journals.sagepub.com/doi/10.1243/0954409001531261)</sup> The configuration of the carbody, pantograph, and the extra voltage bus line was reshaped specifically to reduce aerodynamic noise.<sup>[10](https://zhgdjt.cbpt.cnki.net/portal/journal/portal/client/paper/7eaa306b3b25b3e1f45c39d189f79c2f)</sup>

The nose illustrates the approach. The 700 series nose is 9.2 m long, more than half again the 6.0 m of the Series 300, a shape studied to reduce aerodynamic noise and the pressure pulses produced when a train enters a tunnel.<sup>[6](https://by.genie.uottawa.ca/~mcg3341/AerodynamicsOfHighSpeedTrains.pdf)</sup> These changes produced lower wayside noise and pressure fluctuations, improved riding comfort in tunnels, reduced power consumption, and an increased speed of 285 km/h over some track sections, measured against the Series 300.<sup>[2](https://journals.sagepub.com/doi/10.1243/0954409001531261)</sup>

## Service record

The first sets entered "Nozomi" service on the [Tokaido Shinkansen](https://www.edgepedia.org/tokaido-shinkansen) in March 1999, six years after the Series 300 had opened the same service grade.<sup>[1](https://global.jr-central.co.jp/en/company/about/history.html)</sup><sup> • </sup><sup>[2](https://journals.sagepub.com/doi/10.1243/0954409001531261)</sup> JR West applied its own variant, the 700-7000 series, to the "Hikari Rail Star" service with 2 x 2 seating in ordinary cars.<sup>[8](https://japanrailatlas.com/ja/rolling-stock/series-700)</sup>

JR Central refined the fleet in service: between October 2008 and June 2009 it modified its sixty 700 series sets to raise acceleration from the original 1.6 to 2.0 km/h/s on the Tokaido Shinkansen, giving the timetable more flexibility.<sup>[7](https://japanrailatlas.com/rolling-stock/series-700)</sup> The type's 13.2 MW total output and 2 km/h/s maximum acceleration sit below the later N700 and N700A, which deliver 17.08 MW and 2.6 km/h/s.<sup>[5](https://www.railjournal.com/in_depth/shinkansen-half-a-century-of-speed/)</sup>

A single example survives: car 723-9001, manufactured in 1997 by [Kawasaki Heavy Industries](https://www.edgepedia.org/kawasaki-heavy-industries) and once part of the C1 prototype set, has been on display at Nagoya's SCMaglev and Railway Park since January 2014. It is the mass-production prototype head car that began commercial operation in March 1999, and it replaced the Series 300 car J21 previously shown there.<sup>[7](https://japanrailatlas.com/rolling-stock/series-700)</sup><sup> • </sup><sup>[3](https://jr-central.co.jp/news/release/nws001330.html)</sup>
