  Local (各駅停車, kakueki teisha)

Also known as kakutei (各停) for short. Until 2001 it was called futsū (普通).

  Rapid (快速, kaisoku) (R)

Most services for Hashimoto and Keiō-Tama-Center on the Sagamihara Line, and Takaosanguchi on the Takao Line

  Semi Express (区間急行, kukan kyūkō) (SeE)

Most bound for on the Sagamihara Line. Until 2013, these were weekday-only services called "Commuter Rapid" (通勤快速, tsūkin kaisoku).

  Express (急行, kyūkō) (E)

Most services run from the Toei Shinjuku Line locally and used as the express on the Sagamihara Line via Chōfu in mornings and evenings; other services in mornings and evenings are bound for Keiō-Hachiōji, Takaosanguchi and Takahatafudō.^[2]

  Special Express (特急, tokkyū) (SpE)

Most services bound for Keiō-Hachiōji and Takaosanguchi can make the run from Shinjuku in 37 minutes and 39 minutes respectively.

  Mt. TAKAO (MT)

Reserved-seat supplementary-fare services between Shinjuku and Takaosanguchi on the Takao Line. Services operate weekends and holidays with three round-trips. Trains to Takaosanguchi run nonstop after Meidaimae, while trains to Shinjuku make additional stops to receive passengers.

  Keiō Liner (京王ライナー, Keiō rainā) (KL)

Reserved-seat supplementary-fare services between Shinjuku and either Keiō-Hachiōji or Hashimoto. Services operate seven days a week, with services to Shinjuku in the morning and from Shinjuku in the evening. Fewer trains operate on weekends and holidays. On trains from Shinjuku, reserved seat tickets are only required up to the first train stop after Meidaimae, after which the train's seats become unreserved.

The Shinjuku to Chōfu section opened in 1913 as a 1,372 mm (4 ft 6 in) 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.^[4] The Sasazuka to Fuchu section was double-tracked between 1920 and 1923.^[4]

The extension to Higashi-Hachiōji (now Keiō-Hachiōji) was completed by a related company, Gyokunan Electric Railway, in 1925. This electrified line was built to the Japanese standard narrow gauge of 1,067 mm (3 ft 6 in) in an attempt to seek a government subsidy, and so trains from each railway could not operate on the other's tracks. The subsidy application was rejected on the basis that the line competed with the Japanese Government Railways (JGR) Chūō Main Line, and so the Gyokunan Electric Railway merged with the Keiō Electric Railway Co., the line was regauged to 1,372 mm, and operation of trains from Shinjuku to Higashi-Hachiōji commenced in 1928.^{[citation needed]}

The Fuchu to Nakagawara and Seiseki-Sakuragaoka to Kitano sections were double-tracked in 1929. In 1963, the original terminus at Shinjuku and the streetrunning section on what is today Japan National Route 20 towards Sasazuka Station was moved to an underground alignment.^[5] Additionally the overhead line voltage was increased to 1,500 V DC. The Nakagawara to Seiseki-Sakuragaoka section was double-tracked in 1964.^{[citation needed]} The Kitano to Keiō-Hachiōji section was double-tracked in 1970, and the relocation of the terminal station underground was completed in 1989.^{[citation needed]}

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 will also stop at Sengawa Station.^[6]

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.^[7] The underground section of the Keiō around Chofu Station to Kokuryo was completed in 2012.^[7][8]

The Keiō Line is infamous for its level crossings, of which the 25 lying on the 7.2-kilometer (4.5 mi) section between Sasazuka and Sengawa stations are classified by the Tokyo Metropolitan Government Construction Bureau as akazu no fumikiri as they are closed to road traffic for over 40 minutes in an hour.^[9] Congestion on the Keiō Line is also a concern, with trains often running as close as 1 minute apart during rush hours.^[10] 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.^[11] 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.^[8]

With the completion of the undergrounding between Chofu and Kokuryo Stations in 2012, construction has started on elevating the line between Sasazuka and Sengawa Stations.^[12][13] 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.^[14]

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.^[8]
