The 7000 series (京王電鉄7000系電車 "Keiō 7000 kei densha") is an electric multiple unit (EMU) train which operates on the private railway owned by the Keio Corporation.

History

The 7000 series began service in 1984. At the time, the 6000 series was also built. The 7000 series was built for local train service, and the first sets were five-car sets. The running performance of the new series was nearly the same as the 6000 series. One hundred ninety 7000 series cars were built until 1996.

In 2001, the Keio Corporation changed its policy, and the 7000 series began to be used on Special Express, Semi Special Express, Express and Rapid Earnest trains. In 2004, changes to the control system for the train were undertaken.
