The {{nihongo|Seibu Ikebukuro Line|西武池袋線|Seibu Ikebukuro-sen}} is a railway line of the Japanese private railway operator Seibu Railway. It originates at Ikebukuro Station, a large railway junction in north-western Tokyo, extending to northwest suburbs as far as Tokorozawa, Saitama, and nominally terminates at Agano Station.

The Seibu Chichibu Line from Agano to Seibu-Chichibu Station is an extension. The operation is largely divided into two sections: from Ikebukuro to Hannō Station and from Hannō to Seibu-Chichibu Station.

The section from Hannō to Seibu-Chichibu is single track, but every station except for Higashi-Hanno has passing loops, and trains may pass each other at any stop. There is also a passing loop inside a tunnel where the signal controls bi-directional operation. The rest of all the lines is double track with {{Track gauge|1067mm}} track gauge.

The Ikebukuro Line has three branches with through operation, apart from the Seibu Chichibu Line.

History

The line opened 15 April 1915 as the {{Nihongo|Musashino Line|武蔵野線|Musashino-sen}} (separate from the Musashino Line currently operated by JR East), by the then {{Nihongo|Musashino Railway|武蔵野鉄道|Musashino Tetsudō}}, the predecessor of the present Seibu Railway with the first section from Ikebukuro to Hannō. In 1922, electrification began in three stages from Ikebukuro, until reaching Hannō in 1925. In the late 1920s, a second track was added from Ikebukuro to Hōya Station, and in 1929 the line was extended to Agano Station, the present nominal end. On 25 March 1952, the line was renamed to the Ikebukuro line, and throughout the 1950s and 1960s, the 2-track section was extended in stages until reaching Kasanui yard in 1969.{{citation needed|date=September 2014}}

In 1969, the Seibu Chichibu Line was completed to Seibu-Chichibu Station to begin through operation from Ikebukuro; in 1989, bypass tracks were laid to the Chichibu Railway Main Line; and in 1998, through service via Seibu Yurakucho Line of Seibu to the Tokyo Metro's Yurakucho Line began to Shinkiba Station.{{citation needed|date=September 2014}}

In 2001, a second track of 350 m was built to complete the double-track section from Ikebukuro to Hannō. At the same time, the elevated 4-track section from Nerima-Takanodai to Nakamurabashi opened. This elevated 4-track section was extended to Nerima in 2003.{{citation needed|date=September 2014}}

Station numbering was introduced on all Seibu Railway lines during fiscal 2012, with Seibu Ikebukuro Line stations numbered prefixed with the letters "SI".{{cite web|url= http://www.seibu-group.co.jp/railways/news/news-release/2011/__icsFiles/afieldfile/2012/02/23/20110223eki-number.pdf|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|date= 23 February 2012|work= News Release|publisher= Seibu Railway|location= Japan|language= ja|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|url-status= dead|df= dmy-all}}

From 10 September 2012, 10-car 5050-4000 series sets entered revenue service on the Seibu Ikebukuro Line and Seibu Yurakucho Line, with inter-running through to the Tokyo Metro Fukutoshin Line.{{cite web |url= http://rail.hobidas.com/rmn/archives/2012/09/5050_2.html|script-title=ja:東急5050系が西武鉄道池袋線で営業運転開始 |trans-title=Tokyu 5050 series enters service on the Seibu Ikebukuro Line |date= 10 September 2012|work= RM News|publisher= Neko Publishing|location= Japan|language= ja|access-date= 10 September 2012}}

From 16 March 2013, through running via the Tokyo Metro Fukutoshin Line commenced beyond Shibuya over the Tokyu Toyoko Line and Minatomirai Line to {{STN|Motomachi-Chukagai|x}} in Yokohama.{{cite web|url= http://www.seibu-group.co.jp/railways/news/news-release/2012/__icsFiles/afieldfile/2012/07/24/20120724soutyoku.pdf|script-title= ja:池袋線が東急東横線、横浜高速みなとみらい線との相互直通運転を開始します。|trans-title= Inter-running to commence between Ikebukuro Line and Tokyu Toyoko and Minatomirai Lines|date= 24 July 2012|work= News Release|publisher= Seibu Railway|language= ja|archive-url= https://web.archive.org/web/20120813085929/http://www.seibu-group.co.jp/railways/news/news-release/2012/__icsFiles/afieldfile/2012/07/24/20120724soutyoku.pdf|archive-date= 13 August 2012|access-date= 25 July 2012|url-status= dead|df= dmy-all}}

= Future plans =

In June 2025, JR East and Seibu Railway announced a plan to enable through service between the Seibu Ikebukuro Line to the Musashino and Keiyo Lines by fiscal 2028.{{Cite web |date=2025-06-09 |title=西武池袋線とJRが初の直通運転、2028年度めどに…所沢駅と武蔵野線・新秋津駅の連絡線活用案 |url=https://www.yomiuri.co.jp/national/20250609-OYT1T50040/ |access-date=2025-06-09 |website=Yomiuri Shimbun |language=ja}} The service would be achieved through a junction near Shin-Akitsu Station on the Musashino Line.
