TheMusashino Line (武蔵野線,Musashino-sen) is a railway line operated by theEast Japan Railway Company (JR East). It linksTsurumi Station inYokohama withNishi-Funabashi Station inChiba Prefecture, forming a 100.6 km (62.5 mi) unclosed loop around centralTokyo. Passenger operations are limited to the 71.8 km (44.6 mi) portion betweenFuchūhommachi and Nishi-Funabashi; the Tsurumi to Fuchūhommachi portion, called the "Musashino South Line", is normally used only by freight trains. 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 theKeiyō Line, Musashino Line,Nambu Line, andYokohama Line.[2]
Most services on the Musashino Line are local trains making all stops. Some trains continue through theKeiyō Line past Nishi-Funabashi toTokyo,Minami-Funabashi orKaihimmakuhari.
Other services include:
Tsurumi Station is considered to be the origin of the Musashino Line; trains going clockwise (toward Nishi-Funabashi) are therefore referred to as heading "down" (下り,kudari), while trains going counter-clockwise (toward Fuchūhommachi) are heading "up" (上り,nobori). This is often counterintuitive, as it results in through trains to Tokyo being labeled and numbered as "down" trains while on the Musashino Line; however, such trains switch to "up" after joining theKeiyō Line.
All eastbound (for Nishi-Funabashi) passenger trains begin service at Fuchū-Hommachi Station. Details of the Musashino South Line and other branch lines, which are freight-only sections, can be found below the passenger station list.
Ōmekaidō Station is approximately 10 minutes walk from Shin-Kodaira Station.

Three 209-500 series sets were transferred from theKeiyō Line in 2010-2011, where they were displaced by newE233-5000 series sets and reduced from ten to eight cars per set;[4] eight additional sets were transferred from theChūō–Sōbu Line in 2018-2019. Between 2017 and 2020, E231-0 series sets were transferred from the Chūō–Sōbu Line and the Jōban Line and reduced from ten to eight cars per set to replace the 205 series.[5] In July 2020, the sole E231-900 series set was also transferred from the Chūō–Sōbu Line and reduced from ten to eight cars.[6]
165 and169 series EMUs were used onShinkansen Relay services and laterMusashino rapid services until 2002.115 series EMUs were used onMusashino services from 2002 until the services were downgraded to all-stations "Local" status in December 2010. The 205-0 series sets were built from new for the Musashino Line, entering service from 1 December 1991,[2] and have six motored cars per eight-car set.[4] These were the last 205 series sets to be built from new.[2] The 205-5000 series sets were modified between 2002 and 2008 from displaced formerYamanote Line sets by adding new VVVF-controlled AC motors, and have four motored cars per eight-car set.[4]205 series trains, both 205-0 and 205-5000 serieses, were withdrawn from Musashino Line and currently operated in Indonesia.
Locomotive types seen hauling freight trains include theClass EF64,Class EF65,Class EF66,Class EF81,Class EF200,Class EF210,Class EH200,Class EH500,Class DE10, andClass HD300.
The Musashino Line was initially envisioned as a "Tokyo Outer Loop Line" in a 1927 railway appropriations bill, but was not built for several decades due toWorld War II and its aftermath.[citation needed] Construction finally began in November 1965.[2]
In 1967, a train carryingjet fuel toTachikawa Air Base in western Tokyo exploded while passing throughShinjuku Station[citation needed]. This disaster led to the banning of freight trains on railway lines in central Tokyo and sped the development of the Musashino Line as an alternative route[citation needed]. Because most of the line passed through sparsely populated areas, it was initially envisioned as a freight-only line. However, opposition from local residents, at the same time as the violent landowner battles plaguingNarita International Airport, led the railway authorities to agree to passenger service as well.
The first section of the line betweenFuchū-Hommachi andShin-Matsudo opened on 1 April 1973.[4] Train services were operated using 6-car101-1000 series EMUs, which were modified specially for the line to comply with government regulations concerning fire resistance of trains operating through long tunnels, as the line included the 4,380 m (14,370 ft) Higashi-Murayama Tunnel (東村山トンネル) between Shin-Kodaira and Shin-Akitsu stations, and the 2,563 m (8,409 ft) Kodaira Tunnel (小平トンネル) between Shin-Kodaira and Nishi-Kokubunji stations.[2] Services operated at 15-minute intervals in the morning peak, and at 40-minute intervals during the daytime off-peak.[2]
The southern freight-only line from Fuchū-Hommachi to Tsurumi opened on 1 March 1976.[4] The eastern section of the line from Shin-Matsudo toNishi-Funabashi opened on 2 October 1978.[4]
Inter-running to and from the Keiyo Line commenced on 1 December 1988.[4]
From the start of the 1 December 1996 timetable revision, all of the Musashino Line 103 series sets were lengthened from six to eight cars.[2]
On 20 August 2016,station numbering was introduced with stations on the Musashino line being assigned station numbers between JM10 and JM35.[7][8] Numbers increase in the counter-clockwise direction towards Fuchu-Hommachi.
