The Nambu Line (Japanese: 南武線, romanized: Nanbu-sen) is a Japanese railway line which connects Tachikawa Station in Tachikawa, Tokyo and Kawasaki Station in Kawasaki, Kanagawa. For most of its length, it parallels the Tama River, the natural border between Tokyo and Kanagawa prefectures. It lies along the Tama Hills. It is part of the East Japan Railway Company (JR East) network. The line forms part of what JR East refers to as the "Tokyo Mega Loop" (Japanese: 東京メガループ) around Tokyo, consisting of the Keiyo Line, Musashino Line, Nambu Line, and the Yokohama Line.[2] The name refers to the southern (Japanese: 南) part of the ancient province of Musashi (Japanese: 武蔵) (now Tokyo and northern Kanagawa prefecture), through which the Nambu Line runs.

History edit
The private Nambu Railway opened the line in five stages between 1927 and 1930 (freight branches are omitted):[9]
- 27 March 1927: Kawasaki – Noborito
- 1 November 1927: Noborito – Ōmaru (near Minami-Tama)
- 11 December 1928: Ōmaru – Bubaigawara (then called Yashikibun)
- 11 December 1929: Bubaigawara – Tachikawa
- 25 March 1930: Shitte – Hama-Kawasaki
Passenger trains utilised electric multiple units (EMUs) from the beginning. Freight initially consisted primarily of gravel hauled from the Tama River. When the railway reached Tachikawa and made connection with the Ōme Electric Railway, limestone became one of the main freight commodities. The railway was controlled by Asano zaibatsu, which enabled the transport of limestone from its own quarry in Western Tokyo to its cement plant in Kawasaki without using the government railways.[10]
On 1 April 1944, the railway was nationalised by the imperial government and became the Nambu Line of Japanese Government Railways. After the end of World War II, there were several calls for the privatisation of the line, but the line remained a part of the Japanese National Railways (JNR) until its privatization in 1987.[10]
The postwar growth of the Tokyo urban area resulted in the conversion of most of the farmlands along the Nambu Line into residential areas and increased the passenger traffic on the line. Freight traffic reduced after the opening of the Musashino Line (parallel to the Nambu Line) in 1976 and the discontinuance of the limestone freight in 1998, except for the Nambu Branchline, which remains a major freight route.[10]
Limited-stop "Rapid" services between Kawasaki and Noborito with stops at Musashi-Kosugi and Musashi-Mizonokuchi started on 15 December 1969, but were discontinued by the timetable revision on 2 October 1978.[11] After 33 years, Rapid services between Kawasaki and Tachikawa with more stops started on 9 April 2011, postponed from the originally scheduled 12 March due to the 2011 Tōhoku earthquake and tsunami.[12]
On 20 August 2016, station numbering was introduced with Nambu line stations being assigned station numbers between JN01 and JN26.[13][14] Numbers increase towards in the westbound direction towards Tachikawa. In addition, station numbers JN51 to JN54 were assigned to the branch line stations with numbers increasing in the direction of Hama-Kawasaki.
