Basic data

Services

Although the Chūō Line (Rapid) designation only refers to the section between Tokyo and Takao stations, many trains continue on past Takao to Ōtsuki, with some trains operating through services to other lines. These include both limited express and various special rapid services. For details, see the Chūō Main Line article. In addition, Chūō Line (Rapid) trains do not stop at some stations between Ochanomizu and Nakano stations; for information on those services, see the Chūō-Sōbu Line article.

The Chūō Line (Rapid) uses the two express tracks on the four-track section between Ochanomizu and Mitaka stations. Past Mitaka, trains use both tracks on the remaining double-track section. Since the express tracks do not have platforms at several stations in central Tokyo, even the slowest services of the Chūō Line (Rapid) skip such stations and are therefore called "Rapid" (快速). In addition to the basic type of "Rapid", there are some variations of the service types with fewer stops.

Rapid (快速)
This service is the most common on the Chūō Line (Rapid) route. They stop at all stations west of Nakano. After Nakano, it stops at Shinjuku, Yotsuya, Ochanomizu, and Kanda stations before arrival in Tōkyō Terminal. On weekends and holidays, trains do not stop at Asagaya, Kōenji, and Nishi-Ogikubo stations.
They run between Tokyo on the east side, and Takao/Otsuki on the west side, though some westbound services terminate at stations before Takao, such as Musashi-Koganei, Tachikawa, Toyoda and Hachioji.
Some trains operate through services to the Ōme Line (to as far as Ōme/from Okutama) , Itsukaichi Line (to/from Musashi-Itsukaichi, via Haijima on the Ōme Line), Hachiko Line (to/from as far as Komagawa, via Haijima on the Ōme Line) or the Fuji Kyuko Line (to/from Kawguchiko, via Ōtsuki).
The service's signature color on service diagrams is orange (■).

Chūō Special Rapid (中央特快)  • Ōme Special Rapid (青梅特快)
Four services per hour in off-peak hours make limited stops between Tokyo and Tachikawa. These two services stop at the same stations that Rapid services would stop between Tokyo and Nakano. After Nakano, these services only stop at Mitaka, Kokubunji and Tachikawa, and stop at all stations west of Tachikawa. Eastbound services continue from Nakano as a rapid service.
Chūō Special Rapid stays on the Chūō Main Line to Takao and Ōtsuki, and some services operate beyond Ōtsuki to the Fuji Kyuko Line towards Kawaguchiko.
Ōme Special Rapid spurs to the Ōme Line towards Ōme, stopping at all stations within the line.
The service's signature color on service diagrams is blue (■) for Chūō Special Rapid and green (■) for Ōme Special Rapid.

They mostly terminate at Takao, though a few trains go further to Ōtsuki, or operate through services to Kawaguchiko on the Fuji Kyuko Line, or to Ōme on the Ōme Line. Again, through services to the Ōme Line or the Fuji Kyuko Line stops at all stations on their respective lines.

History

Most of the route of the Chūō Line (Rapid) was built by the Kōbu Railway and later acquired by the Japanese Government Railways in 1906.

Operation of electric multiple unit (EMU) trains on the Chūō Main Line began in 1904. By 1930, the EMU service had reached Tokyo to the east and Asakawa (now Takao) to the west. In 1933, two tracks were added to the existing double-tracked section between Ochanomizu and Iidamachi stations (later closed) to complete the four-track line between Ochanomizu and Nakano. On these additional tracks, express trains (急行電車, kyūkō densha), which skipped all stations except Yotsuya and Shinjuku, were introduced the same year. The express service was renamed "Rapid" (快速, kaisoku) service in March 1961.

Initially, the operation of express/rapid services was limited to weekday peak periods only. Express service began on weekends on March 5, 1944; daytime non-peak operation began on November 9, 1959, but it was limited to weekdays only until April 28, 1966. All day rapid service trains are available since March 14, 2020, when early morning and late night rapid operations began.[2]

Manseibashi Station, located between Kanda and Ochanomizu, was closed in 1943. On the section east of Takao, only Nishi-Kokubunji Station (opened in 1973) and Nishi-Hachiōji Station (opened in 1939) were opened after the start of rapid services.

  • August 20, 1979: 201 series EMUs introduced
  • March 16, 1991: Ohayō Liner Takao/Ōme and Home Liner Takao/Ōme begin operation
  • April 10, 1993: Kokubunji Station added to Ōme Special Rapid stops; Commuter Special Rapid begins operation
  • December 1, 1997: Chūō Main Line-bound 115 series EMUs no longer service Shinjuku Station
  • October 5, 2005: Women-only cars introduced
  • December 26, 2006: E233 series EMUs introduced
  • March 16, 2019: 209-1000 series EMUs commence service.

Future developments

JR East plans to introduce Green (first class) cars on Chuo Line (Rapid) and Ome Line services from fiscal 2021 or later.[3] This will involve adding two bilevel Green cars to 10-car and 6-car E233 series EMU sets, forming 12-car and 8-car sets. Work will be involved in lengthening station platforms and depot facilities to handle the longer trains.[3] In order to compensate the insufficient train sets for regular operations due to existing sets to be undergoing green car addition modifications, two 209-1000 series train sets originally used on the Jōban Line (Local) have been transferred to the Chūō Line. These sets commenced service from 16 March 2019.

High suicide rate

The Chuo Rapid Line is known for a high number of suicides, primarily due to the high speed at which some trains pass through stations on the line.[4]
