At the northern end of the line, some trains continue beyond Ōmiya as far asKawagoeon theKawagoe Line;at the southern end of the line, many Saikyō Line trains continue onward beyond Ōsaki to eitherShin-Kibaon theRinkai Line(operated byTokyo Waterfront Area Rapid Transit) orEbinaon theSotetsu Main Line(via theSōtetsu Shin-Yokohama Line). Moreover, despite the line’s name, some trains only go between Kanagawa and Shinjuku, without continuing to Saitama. Beside the link that connects the Saikyō and Rinkai lines is the JR East Tokyo General Rolling Stock Centre that stores the rolling stock for theYamanote Lineand other types of rolling stock; and the Hinkaku Line which links Saikyo Line to theTokaido Freight Lineand Sotetsu-JR Link Line.

Route
editThe line runs parallel to theYamanote LinebetweenŌsakiandIkebukuro,where it is formally called the Yamanote Freight Line (Japanese:Sơn thủ hóa vật tuyến), and as an alternate route to theTōhoku Main LinebetweenAkabaneandŌmiya,where it is unofficially called the Tōhoku Honsen Secondary Line (Japanese:Đông bắc bổn tuyến chi tuyến). The portion betweenIkebukuroandAkabaneis officially known as the Akabane Line (Japanese:Xích vũ tuyến). For most purposes, JR refers to all of these as part of the "Saikyō Line" when being used for Saikyō Line services.[2]
Service
editThere are three types of trains on the Saikyō Line: "Local"(Các dịch đình xa,Kakueki-Teisha),"Rapid"(Khoái tốc,kaisoku),and "Commuter Rapid"(Thông cần khoái tốc,tsūkin kaisoku).Between Akabane and Musashi-Urawa, Rapid trains stop only at Toda-Kōen, while Commuter Rapid trains, which run during rush hours, stop only at Musashi-Urawa between Akabane and Ōmiya. Between Akabane and Ikebukuro, as well as on the Kawagoe and Rinkai lines, all trains stop at all stations. Between Ikebukuro and Osaki on the Yamanote Freight Line, all trains run limited-stop in both directions, with the Yamanote Line providing all-stations service.[3]

History
editThe Akabane Line opened on 1 March 1885 as a segment of the Nippon Railway Shinagawa Line. The company wasnationalizedin 1906. Electric services on the line began in 1909. From 1972 to 1985, the line was the known as the Akabane Line after being a branch ofYamanote Line.
Before the Saikyo Line, there were several attempts to improve commuter rail service between Saitama and Tokyo. One of the earliest, the Tokyo-Ōmiya Electric Railway(Đông kinh đại cung điện khí thiết đạo,Tōkyō-Ōmiya Denki Tetsudō),was founded in 1928 but went bankrupt shortly thereafter due to rising land values in the area. Later, in 1968, the Tokyo Metropolitan Board of Transportation proposed to run the newToei Mita Lineto centralŌmiya.
Development of the Saikyo Line began as aJapanese National Railwayseffort to quell unrest in Saitama regarding the expansion of theTohokuandJoetsu Shinkansen.During the mid-1970s, local protesters staged sit-ins, demonstrations, and administrative actions to impede the building of the new high-speed lines north of Tokyo. JNR reached a settlement with the activists under which it would build a commuter line to serve these local communities, while being allowed to continue extending the Shinkansen.
The new line, tentatively called the "New Commuter Line"(Thông cần tân tuyến,Tsūkin Shinsen),was built between Ōmiya and Akabane. Through service to Ikebukuro via the existingAkabane Linebegan on 30 September 1985. The Akabane Line name disappeared from daily use from this time. The Saikyo Line was initially troubled by inadequate train control systems which could not keep pace with its frequency of service; however, these issues were worked out during the first month of service.
When the Tōhoku Main Line portion of the Saikyō Line was being built, the stations from Kita-Akabane to Kita-Yono were designated with numbers from 1 to 10; Kita-Akabane Station was known as "New Commuter Line Station No. 1". However, even after names were assigned, passengers complained that each station looked just like the next due to their identical construction. As a result, JNR, in an unusual move, assigned colors to those stations so that they could be told apart from one another.
On 3 March 1986, the Saikyo Line began through service to Shinjuku via the Yamanote Freight Line, which had seen less use by freight services since the opening of theMusashino Linein 1973.[3]Freight services on the former Akabane Line ended in 1999. Services southward to Shibuya and Ebisu did not begin until 16 March 1996, when new platforms were completed to accommodate passenger service.[3]Through services to Ōsaki and the Rinkai Line began on 1 December 2002.[3]
The Saikyo Line has had a particularly severe problem of overcrowding during peak periods, especially during weekday mornings. The opening of theShonan-Shinjuku Linein 2004 and theTokyo Metro Fukutoshin Linein 2008, both of which parallel the Saikyō Line for part of its route, alleviated some of the worst crowding. Problems resulting from overcrowding have included a higher incidence of groping, as well as delays in train schedule caused by longer time taken at each station to pick up and drop off passengers. The Saikyō Line was notorious for having the highest reported number of groping-related incidents (known aschikanincidents) in the Greater Tokyo area.[6]This problem was directly addressed by introducingwomen-only passenger carsduring rush hours, and indirectly addressed by reducing overcrowding problems as a whole.
On 20 August 2016, station numbering was introduced with stations being assigned station numbers between JA08 and JA26.[7][8]Numbers increase towards in the northbound direction towards Omiya.
Beginning 30 November 2019, some Saikyo Line trains travel through toEbinavia the Shonan-Shinjuku Line and the Sotetsu JR-Link Line. In the westbound direction (Omiya to Shinjuku, Osaki, and Ebina), Saikyo Line trains enter the Hinkaku Line after Osaki, stopping at Nishi-Oi and Musashi-Kosugi. After Musashi-Kosugi, trains enter the Tokaido Freight Line track. NearHazawa Yokohama-Kokudai,the train enters the Sotetsu-JR Link Line.

Notes
edit- ^The platform of the Saikyo Line andShonan Shinjuku Line,until 2020, was quite far from theYamanote Lineplatform, and thus was ridiculed as "Minami Shibuya Station"(Japanese:Nam 渋 cốc dịch,Hepburn:Minami-Shibuya-eki,means South Shibuya Station).
