The Keio 6000 series (京王6000系, Keiō 6000-kei) was an electric multiple unit (EMU) train 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 20 m (66 ft) long cars with four pairs of doors per car side. Sets were refurbished from 1986, to extend their service life.

A four-car formation was used on the Keio Dobutsuen Line as a wanman driver-only-operated shuttle service.

The type was withdrawn from service on 13 March 2011.^[5]

DeWa 600 series[]

Three cars were converted to maintenance cars and reclassified as DeWa 600 series in October 2004.^[6] The DeWa 600 series replaced the older maintenance cars of the DeWa 5000 series which was operated since 1995. The remodeling went as follow :

• 6107 (set 6707) → 601 (the cab from car 6707 was transferred)
• 6407 (set 6708) → 621 (a simple cab was added)
• 6457 (set 6708) → 631

The cars received a new grey livery with red and white diagonal stripes.^[7]

The DeWa 600 series was used with ChiKi 290 or sandwiched between cars 601 and 621.^[8] It also served as a shunting vehicle at Wakabadai depot.^[9]

Following the introduction of successor maintenance cars in September 2015, the DeWa 600 series was withdrawn from service and scrapped in April 2016.^[10]
