Interior

History

The first 8000 series trains were introduced in 1992.[3]

Six-car and four-cars sets (and occasionally a pair of four-car sets) used to be operated on splitting services which separated and re-joined at Takahatafudō Station until 2006. From 2013 to 2019, all six- and four-car 0-subseries sets underwent a refurbishment program. Among several technical upgrades, the cabs of the two inner ends were removed to form 10-car sets.[3]

The 8000 series trains are used exclusively on Keio Corporation lines. Thus, unlike some other Keio trains, they do not continue past Shinjuku on to the Toei Shinjuku Line.

Set 8705F was involved on the October 2021 Tokyo attack.

Special liveries

Set 8713 received a special all-over green livery in September 2009 evoking the livery carried by the former 2000 series trains.[4]
