The Odakyu 70000 series (小田急70000形, Odakyū 70000-gata) or GSE (Graceful Super Express) is a Romancecar electric multiple unit (EMU) train type on order by the private railway operator Odakyu Electric Railway in Japan. Two seven-car trainsets are scheduled to enter service on the Odakyu Odawara Line in March 2018.[1]

Design

Two seven-car trainsets are being built by Nippon Sharyo, with the design overseen by Noriaki Okabe Architecture Network.[2] The total cost of the two trains will be approximately 4 billion yen.[2] The trains are finished in a "Rose vermillion" livery with "Romancecar vermillion" and grey body side stripe.[3]

Individual cars are equipped with electro-hydraulic full-active suspension to minimize lateral vibration.[4]

Operations

The trains primarily operate on the Odakyu Odawara Line between Shinjuku in Tokyo and Hakone-Yumoto in Kanagawa Prefecture.[1]

Formations

The trains are formed as seven-car sets of 20 m bogie cars, as follows, with four motored ("M") cars and three non-powered trailer ("T") cars, and car 1 at the western (Hakone/Odawara) end.[5]

Interior

16-seat observation saloons are located at either end of the train, and the side windows of the passenger saloons have one-metre high windows.[3]

History

Initial details of the trains on order were published by Odakyu on 20 October 2016.[4]

The first trainset was delivered from Nippon Sharyo in December 2017,[6] and formally unveiled to the media on 5 December 2017.[3]

The trains entered service on 17 March 2018.[7]
