The , or , is a private railway company operating three lines in Kanagawa Prefecture, Japan. It is a wholly owned subsidiary of holding company SÃ Âtetsu Holdings, Inc. SÃ Âtetsu Holdings is listed on the Tokyo Stock Exchange; 6.58% of it is owned by the Odakyu Electric Railway Company.
Sagami Railway is one of the core companies of the SÃ Âtetsu group. SÃ Âtetsu focuses on railway operations, although formerly it had a more diversified set of holdings, such as bus lines and supermarkets. SÃ Âtetsu is the smallest company of the "Big 15" private railways in Japan, as it has only short lines, but it succeeded in developing towns along its lines in the 1960s and 1970s, with many passengers riding this line. In May 1990, SÃ Âtetsu joined the major railways. In 2010 it had a daily ridership of 623,500
The company operates three passenger (commuter) lines and a freight-only line. All lines are electrified. All the railroads owned or operated by SÃ Âtetsu are entirely within Kanagawa Prefecture, but through services with other rail operators allow SÃ Âtetsu trains to travel into Tokyo Metropolis and Saitama Prefecture.
, SÃ Âtetsu operates the following electric multiple unit (EMU) train types.
Further 20000 series trains will be delivered ahead of the start of inter-running services to and from Tokyu Corporation lines scheduled to commence in late fiscal 2022.
Some withdrawn rolling stock is preserved at Kashiwadai depot.
The Sagami Railway was established in Chigasaki, Kanagawa, in January 1917, to transport gravel along the Sagami River valley. The first section, between Chigasaki and , was opened in 1919, and the line was gradually extended to in 1931. Sagami Railway started direct operation to , but performance was sluggish during the economic depression, and an outflow disaster of Sagami River severely damaged its gravel pits in 1941. This led to Sagami Railway eventual decision to become a subsidiary of Tà Âkyà « in 1941.
The Jinchà « Railway () was established in Seya village (now, Seya-ku, Yokohama) in 1917 and opened its first section from to in May 1926. Jinchà « Railway extended to Yokohama Station in 1933, but its management faced financial difficulties, so the company also became a subsidiary of Tà Âkyà « in 1939, prior to Sagami Railway. The two companies' rail lines were connected at Atsugi Station.
In April 1943, acknowledged by Tà Âkyà «, Sagami Railway took over Jinchà « Railway and named the two lines "Sagami Line" (original section) and "Jinchà « Line" (acquired section). However, in June 1944 during World War II, the Sagami Line and its Nishi-Samukawa branch line were forcefully acquired by the government to use as a bypass between the Hachikà  Line and Chà «à  Main Line in anticipation of airstrikes on heavy industrial facilities around the area. Sagami Line would never return to the hands of Sagami Railway. At the same time, Imperial Japanese Navy Atsugi Airport was opened, so the ridership and freight traffic increased sharply. As a result, Sagami Railway released all management and delegated it to Tà Âkyà «. Under Tà Âkyà «, the line gained electrification to increase the carrying capacity, and in 1944, all passenger lines were electrified.
In June 1947, Sagami Railway employees bought their own shares from Tà Âkyà « and resolved the commission of the Jinchà « Line (renamed as the "Tà Âkyà « Atsugi Line" during Tà Âkyà «'s operation). Sagami Railway continued to develop the Jinchà «/Atsugi Line, which became what is known today as the Sà Âtetsu Main Line. The whole line was fully double-tracked in 1951. In 1968, Sagami Railway began the construction of the Izumino Line. After completing the first extension of the Izumino Line in 1990, Sagami Railway was recognized as one of the "major private railway companies" (大æÂÂç§ÂéÂÂ) in Japan by the , which gives Sagami Railway the qualification to participate in cabinet meetings and parliamentary hearings regarding public transportation policies.
In 1952, Sagami Railway purchased the 25,000 m<sup>2</sup> of land around Yokohama Station's west entrance from Esso, and began to develop to attract department stores.
The Sà Âtetsu Shin-yokohama Line is an approximately 6 km link, which is constructed from Nishiya via to . This line enables through services between the JR East Saikyà  Line and the Sà Âtetsu Main Line by late 2019, as well as between the Tà Âkyà « Tà Âyoko Line, the Tà Âkyà « Meguro Line and the Sà Âtetsu Main Line by March 2023. This project created a railroad which allows residents and commuters alongside the Sà Âtetsu railway lines to better access the Tokyo Metropolis as well as Tokaido Shinkansen by interchanging at Shin-yokohama.
