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.
Special liveries
Set 8713 received a special all-over green livery in September 2009 evoking the livery carried by the former 2000 series trains.[3]
