The or GSE (Graceful Super Express) is a Romancecar electric multiple unit (EMU) train type operated by the private railway operator Odakyu Electric Railway on the Odakyu Odawara Line in Japan since 17 March 2018. Two 7-car trainsets were built by Nippon Sharyo between 2017 and 2018, replacing the 7000 series "LSE" sets.[1]

Design

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

Individual cars are equipped with electro-hydraulic full-active suspension to minimize lateral vibration.[3]

The 70000 series was among the Good Design Best 100 for 2018, eventually receiving the Good Design Gold Award for that year,[4] and the Blue Ribbon Award in 2019.[5]

Operations

The trains primarily operate on the Odakyu Odawara Line between in Tokyo and in Kanagawa Prefecture.[6]

Formations

The trains are formed as seven-car sets of 20m (70feet) 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.[7]

Cars 2, 4, and 6 each have one single-arm pantograph.[7]

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.

History

Initial details of the trains on order were published by Odakyu on 20 October 2016.[3]

The first trainset was delivered from Nippon Sharyo in December 2017,[8] and formally unveiled to the media on 5 December 2017.[9] The second set was delivered from Nippon Sharyo in June 2018.[10]

The first set entered service on 17 March 2018,[11] [12] with the second set entering service on 11 July of that year.[13]
