History

The first 8000 series trains were introduced in 1992.^[2]

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. Now, all six-car and four-car 0-subseries sets are permanently formed as 10-car trains.^[2]

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