History

edit

The trains are designed by Ken Okuyama Design,[2] with exterior painted with sapphire blue to match with the blue sky of the Izu Peninsula. Two eight car sets were manufactured, by Kawasaki Heavy Industries' Hyogo factory (cars 1 to 3)[3][4] and Hitachi's Kasado factory [ja] (cars 4 to 8).[5]

Set RS1 operated a trial run on November 21, 2019,[2] and the trains entered service on March 14, 2020,[6] the day after the 251 series Super View Odoriko sets were retired.

Technical specifications

edit

The car bodies are made of aluminum, and the trains use three phase motors and VVVF inverters.[1] Each car has one door per side; cars 3, 5, and 7 are fitted with pantographs, with the one on car 5 being for emergency use.

Formation

edit

The trains are formed as eight-car sets, with five motored and three trailer cars. Car 1 faces towards Izukyū-Shimoda and car 8 towards Tokyo.[1]

Car 1 is designated as a "premium green car" with a 1+1 private seating layout. The fully power-reclining seats, made of leather and equipped with leg rest and luggage space under each seat, can be swiveled towards the window side for the view of Izu's seaside.

Green car private compartments (Cars 2 and 3)

edit

Cars 2 to 3 are designated as "green cars" with private compartment seating for groups of 4 to 6 people and are priced higher than the "premium green car". Seats are arranged in transverse seating for the 4 person compartments and individual seatings for the 6 person compartments. All private compartments have the electrical power outlets.

edit

Car 4 is designated as the cafeteria, with an open-style kitchen, counter seats, and table seats.

Green car (Cars 5 to 8)

edit

Cars 5 to 8 are designated as regular "green cars"; passenger accommodation consists of 2+1 seating throughout. Each seat is equipped with power outlets and can be reclined. Two single seats on car 5 are equipped with belts for wheelchairs.[7]

Features

edit

All cars, except cars 2 to 4, have a luggage area at the end sections and overhead, and restrooms are available in cars 2, 3, and 7, with multi-accessible toilet located at car 5. All seats except private compartments are equipped with personal reading lights, and all cars feature Wi-Fi connection.
