Operations
9000 series
The 9000 series 8-car sets are used mainly on the Keio Line, the Takao Line, and the Sagamihara Line. These sets are mainly used on Local services during daytime. They are also used on 10-car Special Express and Rapid trains. Sets are coupled to 2-car Keio 7000 series sets to form 10-car trains.
9030 series
The 9030 series 10-car sets are used primarily on inter-running services to and from the Toei Shinjuku Line.
Design
The front end design is based on the design of the Keio 5000 series. The body is made of stainless steel. While most of the sets were built at Nippon Sharyo, some were built at Tokyu Car Corporation. The front portion is made of steel painted ivory white.
The 9030 series sets differ from the earlier 8-car sets in having UV-cutting glass for the wide windows, eliminating the need for roller blinds, and having full-colour LED destination indicator panels.
