The '''Nambu Line''' ({{langx|ja|南武線|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" ({{langx|ja|東京メガループ|links=no}}) around Tokyo, consisting of the [[Keiyo Line]], [[Musashino Line]], Nambu Line, and the [[Yokohama Line]].<ref name="dj364">{{cite magazine|last =Saka |first = Masayuki |script-title=ja:東京メガループ 車両・路線の沿革と現況 |trans-title=Tokyo Megaloop: History and current situation of trains and line  |magazine=Tetsudō Daiya Jōhō Magazine |volume = 43|issue = 364 |pages=28–39 |publisher = Kōtsū Shimbun |location = Japan |language= ja |date = August 2014}}</ref> The name refers to the southern ({{langx|ja|'''南'''|links=no}}) part of the ancient province of [[Musashi Province|Musashi]] ({{langx|ja|'''武'''蔵|links=no}}) (now Tokyo and northern Kanagawa prefecture), through which the Nambu Line runs.

==History==
The private [[Nambu Railway]] opened the line in five stages between 1927 and 1930 (freight branches are omitted):<ref name=":0">{{Teishajo|II|65-69}}</ref>
* 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 unit]]s (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 Line|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.<ref name="harada">{{Cite book |author=Harada |first=Katsumasa |title=南武線いまむかし |publisher=Tamagawa Shinbunsha |year=1999 |isbn=4-924882-28-3 |location=Kawasaki |language=ja |trans-title=Nambu-sen Ima Mukashi}}</ref>

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.<ref name=harada/>

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.
