Ōme Line LocalEdit
Local trains stop at all stations. However, they rarely run along the entire Ōme Line, with services splitting at Ōme Station.
The Ōme Line, at times, runs through services along the Chūō Rapid, Itsukaichi, and Hachikō lines. Supplemental trains during the peak season may also run along the Nambu Line. Trains that operate only on the Ōme Line have "Ōme-Itsukaichi Line" displayed at the front.
- Chūō - Ōme Line through service: Some Chūō Line trains operate through service to the Ōme Line via Tachikawa. Most through services only go as far as Ōme, and stop at all stations on the Ōme Line, except the Holiday Rapid Okutama (See below). There are two other through service variations which uses the Ōme Line as an intermediate line, which are shown below.
- Chūō - Ōme - Itsukaichi Line through service: At rush hours, few Chūō Line trains run through services between Tokyo and the Itsukaichi Line via Haijima. These services are always joined with another through service train, which couples / decouples at Haijima. During morning rush, some trains from Musashi-Itsukaichi on the Itsukaichi Line, and another train from Ōme on the Ōme Line, or from Hakonegasaki / Komagawa on the Hachiko Line, couple at Haijima, and head for Tokyo. During evening rush, the reverse occurs.
- Chūō - Ōme - Hachiko Line through service: As mentioned above, there are through services from Tokyo on the Chūō Line to the Hachiko Line, via the Ōme Line. These trains terminate at Hakonegasaki or Komagawa.
- Ōme - Itsukaichi Line through service: Some Itsukaichi Line operate through service to the Ōme Line via Haijima. They operate between Musashi-Itsukaichi and Tachikawa. Note that these trains do not go on the Chūō Line.
Ōme Liner is replaced to Limited Express "Ōme"（特急「おうめ」） from March 2019.
Holiday Rapid Okutama．AkigawaEdit
Holiday Rapid Okutama and Holiday Rapid Akigawa services run on weekends from Shinjuku (and sometimes from Chiba; Shinjuku-bound services are extended to Tokyo). See their article for more information.

The section between Tachikawa and Ōme was opened in 1894 by the Ōme Railway as a 762 mm (2 ft 6 in) gauge line, extended 2 km as a freight-only section to Hinatawada the following year. Passenger services were extended to Hinatawada in 1898, and the line was converted to 1,067 mm (3 ft 6 in) in 1908. A further freight-only section opened to Miyanohira in 1914, and to Futamatao in 1920. Passenger services were extended to Miyanohira in 1923, the same year the entire line was electrified at 1,200 V DC. The line was further extended to Mitake in 1929, when the company changed its name to the Ōme Electric Railway Co. and the voltage raised to 1,500 V DC in 1930. Passenger services were extended to Mitake in 1935.
The company was nationalized on 1 April 1944, the same year that the Tachikawa to Nagakami section was double-tracked.
The Okutama Electric Railway was constructing a line from Mitake to Hikawa (now Okutama) when it was nationalised, and the line opened on 1 July 1944, creating the present-day Ōme Line.
The Nagakami to Hajima section was double-tracked in 1946, and direct services to Tokyo commenced in 1949. The Hajima to Higashi-Ōme section was double-tracked between 1961 and 1962, CTC signalling was commissioned in 1971, and freight services ceased in 1998.
Former connecting linesEdit
- Okutama Station: The Tokyo Waterworks Bureau operated a 7 km line to the Ogouchi dam during its construction between 1952 and 1957. It featured 23 tunnels and 23 bridges. In 1963 it was transferred to the Seibu Railway, which transferred it to the Okutama Limestone Quarrying Co. in 1978, and although the line is now known as the Mizune Freight Line, it has been out of service for some time.
In February 2015, JR East announced plans to introduce Green (first class) cars on Chuo Line (Rapid) and through-running Ome Line services from fiscal 2020. This will involve adding two bilevel Green cars to 10- and 6-car E233-0 series EMU sets, forming 12- and 8-car sets. Work is now undergoing to lengthen station platforms and depot facilities to handle the longer trains.
