Design

edit

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

Individual cars are equipped with electro-hydraulic full-active suspension to minimize lateral vibration.[5]

The 70000 series was among the Good Design Best 100 for 2018,[2] eventually receiving the Good Design Gold Award for that year,[6] and the Blue Ribbon Award in 2019.[7]

Operations

edit

The trains primarily operate on the Odakyu Odawara Line between Shinjuku in Tokyo and Hakone-Yumoto in Kanagawa Prefecture.[8]

Formations

edit

The trains are formed as seven-car sets of 20 m (65 ft 7 in) 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.[9]

Interior

edit

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.[4]

History

edit

Initial details of the trains on order were published by Odakyu on 20 October 2016.[5]

The first trainset was delivered from Nippon Sharyo in December 2017,[10] and formally unveiled to the media on 5 December 2017.[4] The second set was delivered from Nippon Sharyo in June 2018.[11]

The first set entered service on 17 March 2018,[12][13] with the second set entering service on 11 July of that year.[1]
