History

The 7000 series began service in 1984. The 7000 series was built for local train service, and the first sets were five-car sets, rather than 4, 6 or 10 cars. The running performance of the new series was nearly the same as the Keio 6000 series. By 1996, 190 cars of the 7000 series had been built.

From 2001, 7000 series sets were introduced on Special Express, Semi Special Express, Express, and Rapid trains.

Keio announced in 2010 that 18 more of its 7000 series cars would be converted to VVVF inverter control. By 2012, the entire fleet was retrofitted with VVVF inverter control.From"京王電鉄完全データDVDBOOK"by "株式会社メディアクス".The book was made in 2014 January 30th. The book is in Japanese.
