Design

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

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

Formations

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]
