. Early sets used corrugated panels, while sets made after 1987 had a beaten style. (Some corrugated-style cars were made after 1987 as middle cars for sets made early in production.) The sides were not painted. Fronts of early sets were the same color as the sides. The front designs are of two types, but the difference is minor.

lines. (excluding Inokashira Line) * For daytime operation, 10-car sets or 10-car trains of six-car sets coupled to four-car sets are used as Special Express and Semi Special Express trains. * Eight-car trains of six-car sets coupled to two-car sets are used mainly as Local or Rapid trains.

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 The was an electric multiple unit (EMU) train type in Japan, operated by Keio Corporation on its suburban Tokyo commuter rail network between 1972 and 2011. It was the first rolling stock in Keio's history with long cars with four pairs of d ...

. 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

inverter control. As of 2023, all the train sets have been converted to VVVF inverter control in 2012.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.
