Originally designated as "N300" during the development phase, they formed the next generation of shinkansen vehicles jointly designed by JR Central and JR West for use on both Tokaido and Sanyo Shinkansen lines. ==Design== The 700 series is characterized by its flat 'duck-bill' nose designed to reduce the piston effect as the trains enter tunnels. 16-car units are painted white with blue stripes beneath the windows, and are used for ''Nozomi'', ''Hikari'', and ''Kodama'' services on the Tokaido and Sanyo Shinkansen lines, while 8-car units used for the Sanyo Shinkansen ''Hikari Rail Star'' services have a darker livery (grey with black window areas and a yellow stripe beneath the windows) which also acts to visually deemphasize the units' nose area, resulting in a more streamlined impression. As with the 500 series trains, yaw dampers are fitted between vehicles, and all cars feature semi-active suspension to ensure smooth ride characteristics at high speed. Compared with the small fleet of high-performance, high-cost 500 series trains built for JR West, these trains were designed to give improved ride comfort and interior ambience over the earlier 300 series trains at a lower cost than the 500 series trains. The cost of a 16-car 700 series unit is approximately 4 billion yen compared with around 5 billion yen for a 16-car 500 series train. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「700 Series Shinkansen」の詳細全文を読む スポンサード リンク
