The {{nihongo|Seibu Shinjuku Line|西武新宿線|Seibu-Shinjuku-sen}} is a Japanese railway line owned by the private railway operator Seibu Railway, connecting Seibu Shinjuku Station in Shinjuku, Tokyo with Hon-Kawagoe Station in Kawagoe, Saitama.
The Shinjuku Line is one of two main lines of the Seibu Railway system along with the Ikebukuro Line. The two main lines cross at Tokorozawa Station in Tokorozawa, Saitama. The line serves the western suburbs of Tokyo, connecting them to Shinjuku and other areas of downtown Tokyo.
Description

The line is mostly double-track, except for 1.1 km (1200 yards) of single track between Wakita Junction and Hon-Kawagoe Station. While the section from Seibu-Shinjuku to Takadanobaba is elevated, the line runs at ground level through a suburban area until Saginomiya.
Trains
Seven types of train service are operated on the line: Local, Semi Express, Express, Commuter Express, Rapid Express, Haijima Liner, and Koedo limited express, as shown below. Limited Express trains use Seibu 10000 series EMUs, and a supplementary limited express ticket is required. In addition, operation of the all-seat reserved train "Haijima Liner" using the Seibu 40000 series EMU started from March of 2018. The "Haijima Liner" operates from Seibu-Shinjuku to Haijima on weekends and in both directions on weekdays.{{Cite web |title=「拝島ライナー」上り列車の運行詳細が決定|url=https://www.seiburailway.jp/file.jsp?newsroom/news/file/20230131_haijima.pdf |archive-url= |access-date=4 April 2024 |website=Seibu railway}}
There are regular through operations to the Haijima Line. There are also occasional through services to Seibukyūjō-mae Station in order to bring fans to the Seibu Dome for Saitama Seibu Lions baseball games. The Seibu Shinjuku Line is one of the few major commuter rail lines in Tokyo that does not have through service to the Tokyo Metro or Toei Subway network.
Through service onto the Seibu Kokubunji Line has been suspended since 19 March 2019 because of the reconstruction of Higashi-Murayama Station into an elevated station.{{Cite web |date=29 January 2015 |title=西武鉄道新宿線、国分寺線及び西武園線（東村山駅付近）の連続立体交差事業と鉄道付属街路事業に関する「事業及び工事説明会」を開催しました。 |url=https://www.city.higashimurayama.tokyo.jp/shisei/machi/machidukuri/higashimurayama_inde/news.files/higashimurayama_news33.pdf |archive-url=https://web.archive.org/web/20210926102532/https://www.city.higashimurayama.tokyo.jp/shisei/machi/machidukuri/higashimurayama_inde/news.files/higashimurayama_news33.pdf |archive-date=26 September 2021 |access-date=20 October 2022 |website=Higashi Murayama City Online}}

History
The oldest section of the Shinjuku Line is between Higashi-Murayama Station and Hon-Kawagoe Station. This section was built by the {{Nihongo|Kawagoe Railway|川越鉄道|Kawagoe Tetsudō}} to serve as a freight feeder for the {{Nihongo|Kōbu Railway|甲武鉄道|Kōbu Tetsudō}} between Shinjuku and Tachikawa (now known as the Chūō Main Line). The initial Kawagoe Railway route opened between Kokubunji and Kumegawa in 1894; this portion is now known as the Seibu Kokubunji Line. Its northward extension to Kawagoe, the first part of what is now the Seibu Shinjuku Line, opened in 1895. Following several mergers and name changes between 1920 and 1922, the Kawagoe Railway became part of the Seibu Railway.{{citation needed|date=September 2014}}
In 1927, Seibu Railway built its new dual track, electrified at 1,500 V DC, Murayama Line between Takadanobaba Station on the Yamanote Line in Tokyo and Higashi-Murayama Station to compete with {{Nihongo|Musashino Railway|武蔵野鉄道|Musashino Tetsudō}} (present-day Seibu Ikebukuro Line) and the Japanese National Railways Chūō Main Line, the route being in the middle of the two.{{citation needed|date=September 2014}} The rest of the line was electrified at the same time.{{citation needed|date=September 2014}}
The Higashi-Murayama to Tokorozawa section was double-tracked between 1950 and 1958, with the Tokorozawa to Irimagawa section double-tracked between 1967 and 1975. The rest of the line (except for the section between the Wakita Junction and Hon-Kawagoe Station) was double-tracked between 1980 and 1991.{{citation needed|date=September 2014}}
In 1952, a dual-track extension from Takadanobaba to Seibu-Shinjuku Station was completed. At this time the line was renamed the Shinjuku Line, integrating the Murayama Line and the northern section of the Kawagoe Line. The new Seibu-Shinjuku terminal was built as a temporary station, as Seibu planned to extend the line to the second floor of what is now known as Lumine Est on the east side of Shinjuku Station. This plan was later scrapped due to insufficient space to handle trains longer than six cars.
Seibu-Shinjuku Station was expanded to include a high-rise hotel in 1977.{{cite news|title=西武新宿駅はなぜ遠いのか 幻の東口乗り入れ計画|url=http://style.nikkei.com/article/DGXNASFK2103N_S2A121C1000000|access-date=6 May 2016|work=The Nikkei|date=23 November 2012}}

Station numbering was introduced on all Seibu Railway lines during fiscal 2012, with Seibu Shinjuku Line stations numbered prefixed with the letters "SS"(SeibuShinjuku line).{{cite web |date=23 February 2012 |script-title=ja:西武線全駅で駅ナンバリングを導入します |trans-title=Station numbering to be introduced at all Seibu stations |url=http://www.seibu-group.co.jp/railways/news/news-release/2011/__icsFiles/afieldfile/2012/02/23/20110223eki-number.pdf |url-status=dead |archive-url=https://web.archive.org/web/20150924101130/http://www.seibu-group.co.jp/railways/news/news-release/2011/__icsFiles/afieldfile/2012/02/23/20110223eki-number.pdf |archive-date=24 September 2015 |access-date=27 March 2013 |work=News Release |publisher=Seibu Railway |location=Japan |language=ja |df=dmy-all}}

= Express tunnel =
In the 1980s, Seibu drew up a plan to build an underground line for express trains between Seibu-Shinjuku and Kami-Shakujii, including a new underground station between Seibu-Shinjuku and the Metro Promenade. This plan was indefinitely postponed in 1995 due to costs and a decline in passenger ridership versus previous projections. Seibu was also a bidder to acquire the former JR freight terminal site in 1989, where they planned to build a new underground terminal; Takashimaya won the bid and constructed the Takashimaya Times Square complex on the site.{{citation needed|date=May 2016}} In 2019, the Tokyo Metropolitan Government officially cancelled the plan.{{Cite web |title=西武新宿線「幻の複々線化」正式に中止へ 「無期限延期」から四半世紀 |url=https://trafficnews.jp/post/86309 |access-date=2022-03-28 |website=乗りものニュース |date=22 May 2019 |language=ja}}
Future expansion
= Through operations with the Tokyo Metro Tozai Line =
During the 1960s, Seibu unsuccessfully negotiated with the Teito Rapid Transit Authority to offer through service between the Seibu Shinjuku Line and Tozai Line. Seibu's approach was rejected in favor of through operation with the Chuo Main Line. At Takadanobaba station, the interchange between the Seibu Shinjuku Line and Tozai Line involves passing through a few levels from the elevated Seibu Shinjuku line platform to the underground Tozai line platform. The transfer is considerably crowded during the rush hour, as Takadanobaba is the busiest station on the entire Seibu Shinjuku Line.
