History
The Shinjuku to Chōfu section opened in 1913 as a gauge interurban line electrified at 600 V DC, and was progressively extended in both directions so that the line connected Shinjuku and Fuchu in 1916. The Sasazuka to Fuchu section was double-tracked between 1920 and 1923. Additionally the overhead line voltage was increased to 1,500 V DC. The Nakagawara to Seiseki-Sakuragaoka section was double-tracked in 1964. The Kitano to Keiō-Hachiōji section was double-tracked in 1970, and the relocation of the terminal station underground was completed in 1989.
From the start of the revised timetable introduced on 25 September 2015, Semi Special Express services were also to stop at Sasazuka and Chitose-Karasuyama stations, and Semi Express services added a stop at Sengawa Station.
The flat junction west of Chofu station between the Keiō Line and Keiō Sagamihara Line has been a source of congestion in the entire Keiō network for years. Keiō has reconfigured the station and put the entire junction and Chofu Station underground to improve operations and separate traffic between the two lines. The underground section of the Keiō around Chofu Station to Kokuryo was completed in 2012.
Level crossings and congestion
The Keiō Line is infamous for its level crossings, of which the 25 lying on the section between Sasazuka and Sengawa stations are classified by the Tokyo Metropolitan Government Construction Bureau as as they are closed to road traffic for over 40 minutes in an hour. Congestion on the Keiō Line is also a concern, with trains often running as close as 1 minute apart during rush hours. In 2016, Keiō and the Tokyo Metropolitan Government Construction Bureau proposed that the section between Sasazuka and Chofu be grade separated and widened to quadruple-track to reduce the effects caused by the present bunching on the existing at-grade double-tracked line. Later the proposal evolved to call for two separate sets of tracks each dedicated to express and local services, similar to the Keiō and Keiō New lines between Sasazuka and Shinjuku Stations. The government has planned the grade-separating project for this section of line to be completed by 2022, but this date has been delayed due to land acquisition issues and is now slated to be completed in 2031.
Keiō has proposed a later phase for the whole corridor, which involves building another pair of underground tracks for express services between Sasazuka and Chofu, completing the quadruple-tracking of the corridor until the bifurcation of the Keiō New Line. The design of Chofu Station after the completion of the undergrounding works in 2012 allows for the inclusion of another set of underground express tracks in the future.
