History
| This section needs additional citations for verification. (May 2022) |
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.
- 20 August 1979: 201 series EMUs introduced
- 16 March 1991: Ohayō Liner Takao/Ōme and Home Liner Takao/Ōme begin operation
- 10 April 1993: Kokubunji Station added to Ōme Special Rapid stops; Commuter Special Rapid begins operation
- 1 December 1997: Chūō Main Line-bound 115 series EMUs no longer service Shinjuku Station
- 5 October 2005: Women-only cars introduced
- 26 December 2006: E233 series EMUs introduced
- 20 August 2016: Station numbering introduced with stations being assigned station numbers between JC01 (Tokyo) and JC24 (Takao).[3][4]
- 16 March 2019: 209-1000 series EMUs commence service.
- 11 March 2022: Through services to the Hachikō Line and Itsukaichi Line (except Holiday Rapid services) end.
- 18 March 2023: End of all Rapid Holiday Akigawa services and all Rapid Holiday Okutama services between Shinjuku and Ome.[5][6]
Future developments
JR East plans to introduce Green (first class) cars on Chūō Line (Rapid) and Ome Line services from spring 2024.[7] 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.[7] 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.
Suicides
The Chūō 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.[8]
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) 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.
Commuter Rapid (通勤快速)
- Commuter Rapid services operates weekday evening. It starts service in Tokyo heading west, and stops at Ogikubo and Kichijōji in addition to the stops of the two Special Rapids. 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.
- The service's signature color on service diagrams is purple (■).
Commuter Special Rapid (通勤特快)
- This service only operates on weekday towards Tokyo, where two originates from Ōtsuki, two from Ōme on the Ōme Line, and one from Takao. It stops at all stations until Takao, Hachiōji, Tachikawa, Kokubunji, and Shinjuku and continues as a rapid service from Shinjuku. Again, services from Ōme stop at all stations on the Ōme Line.
- The service's signature color on service diagrams is pink (■).
Musashino (むさしの号)
- The Musashino is a local service train linking Ōmiya to Hachiōji via the Musashino Line. Services enter/exit the Chūō Line at Kunitachi by the freight branch, and stops at all stops from Kunitachi to Hachiōji.
Holiday Rapid (ホリデー快速)
 | This section needs to be updated. (February 2024) |
A variety of Holiday Rapid services running on the Chūō Rapid Line operate during the weekends and holidays to serve passengers.
- The Holiday Rapid Okutama (ホリデー快速おくたま), which runs through the Ōme Line, and Holiday Rapid Akigawa (ホリデー快速あきがわ), which runs through the Itsukaichi Line, are two of them. They couple together, running through the Chūō Rapid Line, from Tokyo / Shinjuku to Tachikawa, through the Ōme Line to Haijima, and decouple. The former heads to Okutama, and the latter heads to Musashi-Itsukaichi.
- The Holiday Rapid Mount Fuji (ホリデー快速富士山) and Holiday Rapid View Yamanashi (ホリデー快速ビューやまなし) are two holiday rapid services that, though nominally called 'Rapid', they stop at stations not less than the Special Rapids (Stops at Shinjuku, Mitaka, Tachikawa, Hachiōji, Takao within the Chūō Rapid Line, and skips stations such as Nakano, Kokubunji, Hino, Toyoda, Nishi-Hachiōji, and also some stations west of Takao.)

Former Service
Local (各駅停車)
- This service operated during early morning and late night, where Rapid service trains would enter Chūō-Sōbu Line tracks within Nakano and Ochanomizu, stopping at all stations where regular Rapid services would skip, namely Higashi-Nakano, Ōkubo, Yoyogi, Sendagaya, Shinanomachi, Ichigaya, Iidabashi and Suidobashi. During this time, Chūō-Sōbu Line local trains only operated between Ochanomizu and Chiba.
- They ran between Tokyo on the east side and as far as Takao on the west side, though, like Rapid services, some westbound services terminate at stations before Takao, such as Musashi-Koganei, Tachikawa, Toyoda and Hachioji. A few services operated through services to Ōme on the Ōme Line.
- The service's signature color on service diagrams is yellow (■).
- To prepare for the installation of platform doors on the Chūō-Sōbu Line platforms and the future addition of Green Cars, Rapid service trains ceased to operate on the Chūō-Sōbu Line tracks after 13 March 2020. Chūō-Sōbu Line local trains will no longer turn around at Ochanomizu during early morning and late night hours.[2]
Itsukaichi Line and Hachikō Line through services
With the exception of the Holiday Rapid Akigawa, through services to the Itsukaichi Line (to/from Musashi-Itsukaichi, via Haijima on the Ōme Line) and Hachikō Line (to/from as far as Komagawa, via Haijima on the Ōme Line) operated until 11 March 2022.[9]
