The Keio 9000 series (京王9000系?) is an electric multiple unit (EMU) train type in Japan, operated by the private railway operator Keio Corporation since 2001 on the Keio Line and its branches in Tokyo and Kanagawa Prefecture.
- 9000 series: original 8-car sets (9701-9708)
- 9030 series: 10-car sets (9730-9749) for use on Toei Shinjuku Line inter-running services from 2006
The 9000 series 8-car sets are used mainly on the Keio Line, the Takao Line, and the Sagamihara Line. ies 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.
The front end design is based on the design of the Keio 5000 series. The body is stainless steel. Most of the sets were built at Nippon Sharyo but some sets 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.
As of 1 April 2013, the fleet consists of eight 8-car 9000 series sets and twenty 10-car 9030 series sets.
