Interior

Passenger accommodation consists of seven-person bench seating situated between the doors with blue upholstery, with smaller bench seats that hold up to four at the car ends. Trains refurbished in 2007 have an interior that is similar to that of the 4000 series. Some cars have a jump seat that folds up to provide space for commuters using wheelchairs.

History

Built from 1982, the 8000 series was designed to help the Odakyu Electric Railway deal with the increasing number of passengers they had to carry from suburbs into the Tokyo region.[3] The 8000 series was the last Odakyu trainset to use their distinctive ivory body with blue accents; all future Odakyu commuter trains would use unpainted stainless steel bodies with the same blue accents.

Starting from 2002, the 8000 series would undergo a program of refurbishment. Improvements include replacement of LED screens, new variable-frequency drive systems and replacement of the lozenge-style pantographs to single-arm pantographs among others.

Set 8255, one of the last two remaining field chopper sets, was withdrawn from service in August 2020. It was carried out of Sagami-Ōno depot to a scrapping facility on 27 October 2020.[4]

Transfer to Seibu Railway

On 26 September 2023, it was announced that Odakyu Railway would be transferring over a number of 8000 series trainsets to the Seibu Railway along with some Tokyu 9000 series trainsets from Tokyu Railway. The transfer is set to take place over five years from 2024 to 2029. Seibu announced that 8000 series sets will be used on the Kokubunji Line.[5] [6] It was later announced on 10 May 2024 that one 8000 series set would be transferred to Seibu Railway and enter service on the Kokubunji Line later in 2024 as part of its fiscal 2024 capital investment plan.[7] The first set to be transferred, 6-car set 8261, was transported from Shin-Matsuda Station to Seibu's Kotesashi Depot via Kawasaki Freight Station on 19 and 20 May 2024.[8] [9]

Accidents and incidents

On 12 August 2013 at about 6:35pm JST,[10] [11] 8000 series set 8261 (operated with set 8058[12]) was struck by lightning. No passengers were hurt as the train was equipped with lightning arresters; however, as a result of the strike, the train was left stalled for about twenty minutes[13] and needed repairs.

On 19 June 2019, set 8264 (operated with set 8064) was severely damaged in a collision with a car stuck at a level crossing between Hon-Atsugi and Aikōishida.[14] Set 8264 was scrapped on 1 April the following year.
