The E8 series (E8系) is a Japanese Shinkansen high-speed train type on order for Tsubasa services announced on 3 March 2020. It is intended to replace the E3 series, raising the top speed of the service from 275 to 300 kilometers per hour (171 to 186 mph). It is designed by Ken Okuyama, in cooperation with Kawasaki Heavy Industries.[2]

The train type is scheduled to enter service on 16 March 2024, the start date of the revised timetable for the year.[3] Though 17 sets were originally planned to be built, this was reduced to 15 sets due to reduced travel demand caused by the COVID-19 pandemic.[4] These sets are to be built by Kawasaki Railcar Manufacturing and Hitachi.[1]

The first set, numbered G1, was delivered to the Sendai depot on 30 January 2023.[5]

Design

The train was designed to invoke the richness of the landscape of the Yamagata region, and the "weaving together of nature and people". The exterior coloring is unchanged from the re-liveried E3 series, also designed by Ken Okuyama: white, evoking the snow of Mount Zaō; deep purple inspired by the Mandarin duck, the prefectural bird for Yamagata Prefecture; and yellow and red for the safflower, the prefectural flower of Yamagata Prefecture.[6]

All cars are equipped with full active suspension.[2]

The increased top speed from 275 to 300 kilometers per hour (171 to 186 mph) is possible due to its 9-meter-long (29 ft 6 in) nose, 3 meters (9 ft 10 in) longer than the current E3 series.[7]

Formation

The E8 uses the same 5M2T-formation as the E3 and E6 series mini-shinkansen, meaning that it consists of 5 powered (motor), and 2 non-powered (trailer) cars.[2][1]

Interior

The 7-car trains have two service classes: ordinary cars and Green cars, with a seating capacity of 355. This is 39 fewer seats than the E3 series trains it replaces. Both seating configurations are 2+2 abreast, as is the case for all other mini-Shinkansen trains. AC power outlets are available in both classes. Both the cabins and vestibules are equipped with security cameras. The green car has room for one wheelchair user, while each ordinary car has room for two. All seven cars are equipped to handle large baggage.

The color scheme of the Green car seating is inspired by the blue waters of the Mogami River, combined with the lush greenery covering Mount Gassan. The ordinary car seating draws inspiration from the traditional process of extracting the color of the safflower, which is why the color gradually becomes less saturated moving from the seat cushion to the headrest. The center aisle carpet was designed based on the image of the safflower, represented by the seats, reflecting on the waters of the Mogami River as it flows between them.[2]
