The W7 series (W7系) is a Japanese Shinkansen high-speed train type on order by West Japan Railway Company (JR West) for use on the Hokuriku Shinkansen when the line is extended from Nagano to Kanazawa in March 2015.[1]

Jointly developed alongside the JR East E7 series, a total of 10 12-car W7 series sets (120 vehicles) are on order.[2] The first W7 series train is scheduled to be delivered in April 2014.[3]

Design

Based on the earlier E2 series trains, the W7 series trains are designed with a "Japanese" theme inside and out, combining futuristic styling with traditional design elements overseen by industrial designer Ken Okuyama together with Kawasaki Heavy Industries.[4] Externally, the roof is finished in a "sky blue" colour, and the bodysides are "ivory white" with "copper" and "sky blue" lining.[5] Manufacture of the W7 series sets will be shared between Hitachi in Kudamatsu, Yamaguchi, Kawasaki Heavy Industries in Kobe, and Kinki Sharyo in Osaka.[6]

The trains have a maximum design speed of 275 km/h (170 mph)*,[7] but in service will operate at a maximum speed of 260 km/h (160 mph)* on the Hokuriku Shinkansen, limited to 240 km/h (150 mph)* on the Joetsu Shinkansen tracks between Omiya and Takasaki, and to 110 km/h (70 mph)* on the Tohoku Shinkansen tracks between Tokyo and Omiya.[1] Increased power output enables the trains to maintain speeds of at least 210 km/h (130 mph)* on the steep gradients of the Hokuriku Shinkansen.[2]

Car 12 (Gran Class) is equipped with full active suspension, and the other cars are equipped with semi-active suspension.[7]

Formations

The W7 series 12-car sets will be formed as shown below.[8]

Cars 3 and 7 are each equipped with a single-arm pantograph.[8]

Interior

The 12-car trains have accommodation in three levels of service: Gran Class, Green car, and Standard cars, with a total seating capacity of 934.[1] Gran Class seating (car 12) is arranged 2+1 abreast with a seat pitch of 1,300 mm (51 in), Green car seating (car 11) is arranged 2+2 abreast with a seat pitch of 1,160 mm (46 in), and ordinary seating (cars 1 to 10) is arranged 3+2 abreast with a seat pitch of 1,040 mm (41 in).[7] AC power outlets are provided for each seat in all three classes.[7] The Gran class seats are supplied by Toyota Boshoku.[9] Car saloons and vestibule areas are equipped with security cameras.[5]

History

In January 2012, the head of JR West's Kanazawa Division revealed that new trains for the Hokuriku Shinkansen would be developed in conjunction with JR East, and that test running would need to be conducted during the winter season a year before the line opening to thoroughly test the ability of the trains to cope with snowy conditions.[10]

Details of the new trains were formally announced jointly by JR East and JR West on 4 September 2012.[5] The design of the logo to be applied to the sides of cars 1 and 12 was officially unveiled in February 2014.[11] Consisting of a number "7" in silver stylized as an arrowhead, the logo includes the lettering "West Japan Railway Company".[11]

Future developments

The first W7 series train is scheduled to be delivered to Hakusan Depot in April 2014.[3]
