Tokaido Main Line (JR East) service pattern diagram

This section is operated by East Japan Railway Company (JR East).

The Tokaido Main Line in the Greater Tokyo Area has local services (普通 Futsū), and also two rapid services called Rapid Acty (快速アクティー, Kaisoku Akutī) and Commuter Rapid (通勤快速, Tsūkin Kaisoku). It runs on dedicated tracks parallel to the Yamanote Line between Tokyo and Shinagawa, the Keihin-Tōhoku Line between Tokyo and Yokohama, and the Yokosuka Line between Yokohama and Ōfuna. Some Shōnan–Shinjuku Line trains share the segment south of Yokohama to Ōfuna and Odawara.

The Ueno–Tokyo Line, a JR East project, extended the services of the Utsunomiya Line, the Takasaki Line, and the Joban Line to Tokyo Station, allowing for through services to and from the Tokaido Line from March 2015.[1]

Almost all trains along this section of the line have bi-level "Green Cars" with forward-facing seats, with each set of trains having 2 of them. Green Cars can be used after paying an additional fee.

Local: Some operate through service from/to Numazu or Ito

• Some trains run through services beyond Atami, as far as Numazu.
• With the Ueno-Tokyo Line, Utsunomiya Line Rapid Rabbit and Takasaki Line Rapid Urban services now run along the Tokaido Line, and stop at all stations on this line. As such, the two services are classified as 'Local' service trains within the Tokaido Line. Likewise, Tokaido Line Rapid Acty services now run up to the Utsunomiya Line.
• Shōnan Liner services are special, all-reserved commuter express trains with comfortable seating. They operate from Odawara to Tokyo on weekday mornings, with a few services terminating in Shinagawa. Return services run from Tokyo to Odawara on weekday evenings. Like commuter rapid trains, Shōnan Liner services normally make no stops between Shinagawa and Fujisawa. Between Fujisawa and Odawara, varying stops are made. In addition to the standard fare, a reserved seat fee of ¥500 is required to use the Shōnan Liner.
• Keihin-Tōhoku Line stations between Tokyo and Yokohama officially are a part of the Tōkaidō Main Line. These stations are: Yūrakuchō, Hamamatsuchō, Tamachi, Ōimachi, Ōmori, Kamata, Tsurumi, Shin-Koyasu, and Higashi-Kanagawa.
• Yokosuka Line stations between Tokyo and Ōfuna officially are a part of the Tōkaidō Main Line. These stations are: Nishi-Ōi, Musashi-Kosugi, Shin-Kawasaki, Hodogaya, and Higashi-Totsuka. The route of the Yokosuka Line between Shinagawa and Tsurumi is separate from the main line and is referred to as the Hinkaku Line, on which Nishi-Ōi, Musashi-Kosugi, and Shin-Kawasaki stations are located.
• Shōnan–Shinjuku Line operates through services to the Tōkaidō Main Line. Trains operate from the Takasaki Line to Ōsaki and enter the Yokosuka Line at Nishi-Ōi to Totsuka then switches tracks to the Tōkaidō Main Line towards Odawara, and vice versa. Rapid Service stop at all stations on the Tōkaidō Main Line (Totsuka - Odawara), while Special Rapid Service operate the same pattern as a Rapid Acty Service.

The Tokaido Line between Atami and Maibara is operated by JR Central, and covers the Tōkai region - Shizuoka Prefecture, Aichi Prefecture, and Gifu Prefecture.

Track diagram around Minami-arao Junction

Abstract track diagram between Ōgaki and Sekigahara

Both the Mino-Akasaka and Tarui branch lines separate from the Main Line at Minami-Arao junction (南荒尾信号場), located 3.1 km west of Ōgaki Station.

Between Ōgaki and Sekigahara, there is a 25 per mil grade. In 1944, a single track bypass was built to avoid this steep slope of the main line and the old westbound track was removed.

The western part of the Tōkaidō Main Line from Maibara to Kōbe is operated by JR West and forms the main trunk of the company's Urban Network in the Osaka-Kobe-Kyoto metropolitan area. Although the line is divided into three segments, known as the Biwako Line, JR Kyoto Line, and JR Kobe Line, they are part of a single contiguous network, with many services traversing multiple sections. The Biwako Line includes a segment of the Hokuriku Main Line. Some services on the Kosei, JR Takarazuka and Gakkentoshi lines run through onto the Tōkaidō Main Line.

The section between Maibara and Kyoto is known as the Biwako Line. The line also includes the section of the Hokuriku Main Line between Maibara and Nagahama, where some Kyoto-bound trains originate.

The section between Kyoto and Osaka is known as the JR Kyoto Line. Trains from the Biwako and Kosei lines travel through onto the JR Kyoto Line and continue west towards the JR Kobe Line at Osaka.

The westernmost section between Osaka and Kōbe is part of the JR Kobe Line, which continues west to Himeji on the Sanyō Main Line. Although Kōbe is the official terminus of the Tōkaidō Main Line, most trains continue to Nishi-Akashi, Himeji and beyond.

• Ninomiya Station: The Shonan Horse-drawn Tramway opened a 10 km line to Hatano in 1906 to haul tobacco. Steam locomotion was introduced in 1913. Passenger services ceased in 1933, and the line closed in 1935.
• Odawara Station: The Japan Tobacco and Salt Public Corporation operated an approximately 1 km line to its factory, electrified at 1,500 V DC, between 1950 and 1984. The line was also serviced by the adjoining Odakyu Odawara Line from its Ashigara station.

• Atami Station: In 1895, a 10 km 610 mm (2 ft) gauge handcar line opened to Yoshihama, and was extended 4 km to Odawara the following year. In 1907, the line was converted to 762 mm (2 ft 6 in) gauge and steam locomotives were introduced. The line closed in 1923 as a result of the Great Kanto earthquake.
• Numazu Station: The Sunzu Electric Railway opened a 7 km line to Mishima-Tamachi on the Izuhakone Railway Sunzu Line in 1906. In 1915, the line was truncated 1 km to connect at Mishima-Hirokoji, and the line was electrified at 600 V DC in 1919. The line closed in 1961 following the destruction of the Kisegawa bridge during a flood.
• Yoshiwara Station: The Fuji Horse Tramway (富士馬車鉄道, Fuji Basha Tetsudō) opened a 610 mm (2 ft) gauge line to Ōmiya (presentday Fujinomiya) in 1890. The Fuji Minobu Railway (富士身延鉄道, Fuji Minobu Tetsudō) purchased the tramway in 1912, converted it to a 1,067 mm gauge steam railway the following year and gradually extended it (eventually becoming the Minobu Line). In 1924, the company built a new alignment which connected to Fuji station on the Tokaido main line, at which time the original section from Omiya to Yoshiwara closed.
• Shimizu Station: Shimizukō Line from 1916 to 1984.
• Shizuoka Station:
  • The Abe Railway opened a 9 km 762 mm (2 ft 6 in) gauge line from Inomiya (approximately 2 km from Shizuoka) to Ushizuma in 1914 to haul timber. Plans to extend the line to Shizuoka did not eventuate and the line closed in 1934.
  • The Shizuoka Electric Railway opened a 2 km line to Anzai, connecting to its Shimizu Line, electrified at 600 V DC, between 1922 and 1926. The line closed in 1962.

• Yaizu Station: A 5 km 610 mm (2 ft) handcar line operated to Fujieda between 1891 and 1900.
• Fujieda Station: The Tōsō Railway opened a 4 km 762 mm (2 ft 6 in) gauge line to Ote in 1913, and by 1926 had extended the line progressively in both directions for a length of 38 km from Jitogata to Suruga-Okabe, although in 1936 the 5 km section from Suruga-Okabe to Ote was closed. In 1943, the company merged with the Shizuoka Railway (see Fujiroi Station below), and in 1948, a 7 km line between Mitsumata and Jitogata opened, linking the two sections. This section of the combined line closed between 1964 and 1970.
• Shimada Station: The Fuji Prefectural Government opened a 3 km 610 mm (2 ft) gauge handcar line in 1898 to haul timber. In 1944, following the destruction of the nearby Tokaido Line bridge over the Oigawa, it was proposed to use the alignment of this line as a replacement, including a 930 m wooden bridge over the river. The bridge was about 25% completed when the end of the war resulted in the termination of the proposal. A diesel locomotive was introduced in 1955 to haul construction material for the construction of the adjacent national highway, and the line closed in 1959.
• Kikukawa Station: The Joto horse-drawn tramway opened a 15 km 2 ft (610 mm) gauge line to Ikeshinden in 1899. In 1923, the line was converted to 762 mm (2 ft 6 in) gauge, and a single-cylinder diesel locomotive introduced. The line closed in 1935.
• Fukuroi Station:
  • The Akiba horse-drawn tramway opened a 12 km 762 mm (2 ft 6 in) gauge line to Enshumori-Cho in 1902. In 1926, the company renamed itself the Shizuoka Electric Railway, converted the line to 1,067 mm (3 ft 6 in) gauge and electrified it at 600 V DC. The line closed in 1962.
  • The Shizuoka Railway opened a 10 km 762 mm (2 ft 6 in) gauge line to Yokosuka in 1914, extending it 7 km to Mitsumata in 1927. The company merged with the Fuji-sho Railway in 1943 (see Fujieda Station above), and in 1948, a 7 km line between Mitsumata and Jitogata opened, linking the two sections. This section of the combined line closed between 1964 and 1967.

• Hamamatsu Station: The Dainippon Railway opened a 7 km, 762 mm (2 ft 6 in) gauge line to Kuniyoshi in 1909. In 1919, the line was acquired by the Enshu Railway Line, which closed the first 1 km of the line in 1925, so the new connecting station became Enshu-Magome. The line closed in 1937.

• Okazaki Station:
  • The Nishio Railway opened a 762 mm (2 ft 6 in) gauge line to Nishio in 1911, and extended it to Kira-Yoshida on the Meitetsu Gamagōri Line between 1915 and 1916. In 1926, the company merged with the Aichi Electric Railway, which between 1928 and 1929 converted the line to 1,067 mm (3 ft 6 in) gauge, electrified it at 600 V DC, and connected it to the line from Shin-Anjō on the Meitetsu Nagoya Main Line at Nishioguchi. The line to Nishio closed in 1962.
  • A 6 km tram line connected to the Meitetsu Koromo line at Okazaki-Ida Station, which between 1929 and 1962 connected to the Meitetsu Mikawa Line at Uwagoromo, the tramway also closing in 1962.

• Owari-Ichinomiya Station: The 6 km Meitetsu line to Okoshi, electrified at 600 V DC, opened in 1924. When the voltage on the Meitetsu main line was increased to 1,500 V DC in 1952, services were suspended on this line. The substitute bus service proved so popular the line was closed rather than upgraded.

• Ogaki Station: The Seino Railway opened a 3 km line from Mino-Akasaka to Ichihashi in 1928, and operated a passenger service from 1930 to 1945.
• Arao Station (on the Mino Akasaka branch): A 2 km freight-only line to the Mino Okubo limestone quarry operated between 1928 and 1990.

• Nishinomiya Station: A 2 km freight-only line was opened in 1944 to connect to Mukogawa Station on the Hanshin Main Line. As the former was 1,067 mm (3 ft 6 in) gauge, and the latter 1,435 mm (4 ft 8 ¹⁄₂ in) gauge, some tracks at Mukogawa were dual gauge. Service on the line ceased in 1958, but it was not formally closed until 1970.
• Rokkomichi Station: A 5 km line to Kobe Port opened in 1907, electrified at 1,500 V DC. Passenger services ceased in 1974, and the line closed in 2003.
