The East Kanagawa area line (I boil Kanagawa and naive one noodles) grows from Sagami Railway (following, Sotetsu) main line Nishiya Station to the neighborhood of JR Tokaido goods line Hazawa, Yokohama freight station and is the pike of the plan to bind Tokyu Corporation (following, Tokyu or Tokyu) Toyoko Line, Meguro Line Hiyoshi Station together more via Shin-Yokohama Station of there.

I describe the both sides of Sotetsu, JR direct communication line performing mutual extension operation with JR East at Hazawa Station that Sotetsu Line sets up near Hazawa, Yokohama freight station (tentative name) and Sotetsu, the Tokyu direct communication line performing mutual extension operation with Tokyu Line at Hiyoshi Station in this clause.

Sotetsu, JR direct communication line was said as of (2014) for 2,014 years that 2018 (30, Heisei) year, Sotetsu, Tokyu direct communication line were going to open it each (2019) in April in 2019, but it was announced that it was (2016) in August in 2016, and it was postponement as for the latter as for the former each for "2022 (34, Heisei) year second half year" for "2019 (31, Heisei) year second half year" [1].

Plan summary

According to the thing announced formally (2012) by October in 2012, it is as follows.

This route builds the connecting line of total extension 12.7 kilos from Sotetsu Main Line Nishiya Station to Tokyu Toyoko Line, Meguro Line Hiyoshi Station, and Hazawa (the neighborhood of JR Tokaido goods line Hazawa, Yokohama Station), Shin-Yokohama, each station of new Tsunashima (the neighborhood of Tokyu Toyoko Line Tsunashima Station) are established as a way station (each new planned station name names it tentatively).

I am going to perform mutual extension operation with Tokyu Line each at JR Line, Hiyoshi Station at Hazawa Station via this route from the various quarters of Sotetsu Main Line and Izumino Line. It is said with "a Sotetsu, Tokyu direct communication line" in the latter "a Sotetsu, JR direct communication line" in the former, and "East Kanagawa area line" is comprised by the route of these two (each route name names it tentatively). In addition, it is a route linking the eastern area of Kanagawa, but is labelled as "downtown area direct communication project" in Sotetsu because it is a route running in the downtown area of Tokyo.

Shin-Yokohama Station becomes the connection point of Sotetsu, Tokyu both companies (joint use station), and, in the Nishiya Station area, in Sotetsu, the Hiyoshi Station area, a fare of Tokyu is going to be applied to after the station.

Planned route of the train

The entry of route on the JR side enters the line at Hazawa Station on the way near Tokaido goods line Hazawa, Yokohama Station and does a change line in a track of Yokosuka Line near Tsurumi Station [2]. I trace the route same as Shonan Shinjuku line and go to Shinjuku Station (or the Omiya Station area of Ikebukuro Station and the station beyond) afterwards via Musashi-Kosugi Station, Osaki Station, Shibuya Station. In addition, I entered Yokosuka Line and was added a plan to Shinagawa Station, Ueno Tokyo line way that entered Tokaido Line more, and left for each line (or either) of Ueno Station and Utsunomiya, Takasaki, Joban of Tokyo Station or the station beyond (2013) in December in 2013.

It is written in the homepage of Sotetsu, "I assume it on the basis of a route leaving for Shibuya, the Shinjuku area through the route of so-called Shonan Shinjuku line." about the direct communication to JR Line as of (2016) for 2,016 years [3], and it is in the route to communicate Saikyo Line directly to Yokosuka Line via Tokaido goods line by the route map of the homepage of the Japan Railway Construction, Transport and Technology Agency (railroad, transportation mechanism) near by in the point from junction, Osaki Station for the sake of Musashi-Kosugi Station from Hazawa [4]. Shonan Shinjuku line and Saikyo Line use the same track in during Osaki Station and Ikebukuro Station, but it is unknown what you would do to which system and performing direct driving (whether you assume it the new system which or does a lapel in Shinjuku) or direct communication to Shinagawa, the Tokyo area at present.

I join a track of Tokyu near Hiyoshi Station and do the entry of route on the Tokyu side when the train of 2 systems going to the Toyoko Line Shibuya Station (Tokyo Metro Fukutoshin Line Shinjuku-Sanchome Station and Wakoshi Station or former from the station) area and the Meguro Station area is operated.

About the Toyoko Line side, I carry out mutual extension operation with Yokohama rapid transit railway Minatomirai Line from Yokohama Station that is the terminal [5]. Almost all trains perform mutual extension operation, and Toyoko Line and Minatomirai Line perform integral use virtually as one route. Furthermore, the mutual extension operation with Fukutoshin Line (and including Seibu Ikebukuro Line and the Tobu going up to Tokyo line of there) started (2013) at Shibuya Station that was other terminal from March 16 in 2013, too. But the companies communicating Fukutoshin Line directly mutually do not mention the entry of to this route, and the right or wrong of the entry of to Shibuya and to the north does not become clear. About the Meguro Line side a city planning city draft briefing session (it became clear than the Tokyu side person in charge in 〉) in 〈 2010 in 2010 to assume around four Toyoko Line, around ten Meguro Line about the service number at 14 an hour rushes in the morning of the Sotetsu, Tokyu direct communication line.of the Yokohama-shi holding In addition, further service and the entry of to Tokyo Metro Namboku Line, Saitama high speed rail line, Toei Subway Toei Mita Line of the Meguro Station beyond are examined and announce that 9 formation produces direct communication correspondence vehicles to Sotetsu in Middle management plan 2016 of the station in Tokyo Traffic Bureau which, of these, runs Toei Subway Toei Mita Line.

Meguro Line was likely to be the entry of route to the Tokyu side, but, in the item called "the effect after the completion" in the downtown area direct communication project placing in an official web site of Sotetsu, as for Sotetsu Line and the test calculation in the time required between the downtown areas, judging from what was announced and track capacity and a service plan, only Meguro Station is listed in the plan summary which Yokohama-shi published in (2010) in 2010 at first only for Sotetsu, Tokyu direct communication line in the time required to Shibuya Station (Toyoko Line).

Detailed

City planning is decided a Sotetsu, JR direct communication line, a Sotetsu, Tokyu direct communication line together.

  • The maintenance main constituent is incorporated administrative agency Japan Railway Construction, Transport and Technology Agency. I build it, and it is run by so-called top and bottom separation method.
  • Site acquisition costs are approximately 9,100 million yen, roadbed costs approximately 29,100 million yen, cost of equipment approximately 21,500 million yen, other 8,600 million yen, and the total business expense of the Sotetsu, JR direct communication line (Nishiya Station - Hazawa Station interval) is expected to go up it to approximately 70 billion yen in total.
  • The total business expense of the Sotetsu, Tokyu direct communication line (Hazawa Station - Hiyoshi Station interval) is expected to amount to approximately 195,700 million yen and utilizes the assistance system that Ministry of Land, Infrastructure and Transport began for the maintenance of the urban traffic base from 2005 (17, Heisei) year. In addition, city railroads apply to the country for the application of the convenience increase method with a railroad, transportation mechanism and, as for by a one-third, a person of Kanagawa that is a country, the jurisdiction local government and Yokohama-shi of 3 bears a business expense, and the mechanism owns a route and is going to be run the system in the form that Sotetsu, Tokyu both companies pay the track fee for use.
  • I build the whole line with a double track between the 1,067mm gauge (as for the gauge of a track, common throughout three companies of Sotetsu, JR East, Tokyu).
  • I enter underground near Nishiya district center and, in the Nishiya Station - Hazawa, Yokohama Station - new Tsunashima Station interval, build the whole line except a part of the neighborhood of Hazawa Station in a tunnel (underground cable).
  • I build the new Tsunashima Station - Hiyoshi Station interval as light section (horizon method or overhead wire).
  • At first I start construction of approximately 2.7km of the Sotetsu, JR direct communication line as the first construction of this route from 2009 (21, Heisei) year. As the second construction, I am going to start construction of approximately 10km of the Sotetsu, Tokyu direct communication line later.
  • I did it when I let I led, and a Sotetsu, JR direct communication line start a business by the original plan (2015) in April in 2015. I run in Tokaido goods line from Hazawa Station and do a change line to Yokosuka Line (article crane line) from the line near Tsurumi Station (there is not the setting plan of the station) on the way and perform direct driving to Shinjuku Station by a route same as Shonan Shinjuku line [6]. In addition, I opened Ueno Tokyo line (Tokyo Station - Ueno Station interval, Tohoku Main Line train line) (2015) in JR on March 14 in 2015, but there was the request of Kanagawa and Yokohama-shi (2013) in Sotetsu from December in 2013, and it wanted to be announced what the entry of to Tohoku Main Line (Utsunomiya Line), Takasaki Line, Joban Line through the separately line and the line examined with the Shinjuku Station entry of, and [7] showed the thought that Fumiko Hayashi of Mayor Yokohama called for concrete examination of the entry of to the Tokyo area for Sotetsu and JR East in September for the next 2,016 years [8]. But, this case, the connecting line of the grade separation is necessary for the Tsurumi Station yard or the Shinagawa Station yard (and the neighborhood of yard of both stations) frequently between Tokaido Main Line and an article crane line when I drive (the track is connected to Yokosuka Line now in both stations at mutual intervals with Tokaido Main Line, but the Tokyo area through train will go by way of Kawasaki Station whereas Shinjuku area through train becomes Musashi-Kosugi Station way from the difference of the route when it is all a grade crossing and, therefore, the frequence driving from Sotetsu to the Tokyo area is difficult under the present conditions and still do a change line to Tokaido Main Line from Yokosuka Line at Tsurumi Station). In addition, I do not mention the direct driving to these both lines in Sotetsu and JR East although the direct communication to Yokosuka Line and Sobu Express Line is possible.
    • Announce a railroad, the transportation mechanism by the reason of delays of the construction afterwards that postpone the opening of business time of Sotetsu, the JR direct communication line before 2018 (30, Heisei) year in (2013) in 2013 [9]; [10]. Furthermore, as for the Sotetsu, JR direct communication line, as for the Sotetsu, Tokyu direct communication line, postponement to the second half year was announced in 2022 (31, Heisei) year for the second half year in 2019 (31, Heisei) year in August, 2016 [1].

Construction of the route

between Futamatagawa - Hiratsuka

When I arrive between Futamatagawa - Hiratsuka, decision していなかったところ Sagami Railway acquires a license, and I hang it in (1999) in 1999 from (1976) in 1976, and the business main constituent is inaugurated as Izumino Line between Futamatagawa - Shonandai. 湘南台 - 平塚間については現在も相鉄が延伸免許を保持しているが、実現する見通しはまだ立っていない。 そのため、本格的な着工に向けた協議は同線内における通過運転実施もしくは本路線完成前後になる予定である。

東京都心・埼玉県方面 - 二俣川間

かつて、運輸政策審議会の第7号答申および第18号答申による「神奈川東部方面線」として、相鉄がいずみ野線を二俣川駅から延伸して新横浜駅までを建設し、東京急行電鉄大倉山駅方面から新横浜駅まで建設する新線と接続して相互乗り入れを行う計画が持ち上がったが、計画は長らく進まなかった上、バブル崩壊のあおりも受け、計画は事実上停止した状態であったが、21世紀に入り、それが実現に向けて再び動き出した。

相鉄は当初、神奈川東部方面線という計画について、ターミナルである横浜駅の乗客が減少するという致命的な理由を始めとするいくつかの問題点からこの計画に乗り気ではなかった。しかし、少子高齢化による乗客数の減少という将来を見据えて考えを一転させ、東京都心および埼玉県方面への乗り入れに対して意欲的な姿勢をとるようになった。そして、2004年9月、路線の利便性を高めるために横浜駅を経由しないJRとの直通運転計画に踏み切ることになった。

相鉄とJRの計画は、神奈川県横浜市が計画していた「神奈川東部方面線」に近いものであったが、新横浜駅を経由しないため、新たな計画が実現した場合に期待される効果は、県央部から都心への時間短縮効果のみであった。そのため、県や市は「そのままの計画では効果が薄い」として計画に介入を行った。さらに、この計画が実現すれば横浜駅で相鉄から東横線に乗り換えて東京都心へと向かう乗客をJRに奪われることを危惧した東急が2005年度末頃から計画に参加することになる。その結果、相鉄とJRの直通運転の計画を据え置きつつ、さらにこれを延伸するという形で費用は増えるものの新横浜駅を経由した東急との直通運転も行うということで得られる効果がより多い「神奈川東部方面線」として整備して行くこととなった。運輸政策審議会の答申内容からは若干変わっているが「神奈川県央部と新横浜駅から東京・埼玉方面を乗り換えなしでつなぐ」という目的は変わっていない。

この計画に従って、2006年(平成18年)5月25日に西谷 - 横浜羽沢間については相鉄が単独で、日吉 - 横浜羽沢間については相鉄・東急が共同で、それぞれ国土交通省都市鉄道等利便増進法に基づく「営業構想」の認定を申請した。また、鉄道・運輸機構も同日に西谷 - 横浜羽沢間および日吉 - 横浜羽沢間の「整備構想」の認定を申請し、同年6月9日に西谷 - 横浜羽沢間が、23日に日吉 - 横浜羽沢間がそれぞれ営業構想および整備構想の認定を受けている。

そして11月21日に西谷 - 横浜羽沢間の速達性向上計画が国土交通大臣に認定され、同日提出された日吉 - 横浜羽沢間の速達性向上計画も2007年(平成19年)4月11日に国土交通大臣に認可された。10月にはまず西側の相鉄・JR連絡線建設についての沿線住民向け事業説明会も開催され、本路線の着工に向けた具体的な計画が進行、相鉄・JR直通線について2009年度中の着工を目指すと発表された。なお、前述したが相鉄・JR直通線は2009年(平成21年)10月20日に国土交通省から工事施工認可を受けている。さらに相鉄・東急直通線の綱島駅については、同駅東側にある綱島街道の真下に新綱島駅を設置する計画に変更した。

西谷駅から横浜羽沢駅付近までの連絡線は、当初2005年に着工して2010年頃に開業する予定とされていたが、前記の通り東急との相互直通運転計画が浮上したこともあり、JRとの相互直通運転は2015年4月を目処に開始することとしていた。しかし、工事の遅れなどを理由に2013年4月23日には鉄道建設・運輸施設整備支援機構が2018年度内の開業に延期すると発表[9]、さらに2016年8月26日に2019年度下期への再度の延期を発表した[1]。なお、東急との直通線における開業時期についても2022年度に延期した。

本路線が完成すると、相鉄のターミナル駅である横浜駅を経由しなくても直接、相鉄沿線から東京都心方面へ向かうことができるようになるため、同駅の利用者減少が予想される。そこで、相鉄は横浜駅 - 海老名駅間において特急の導入や、本路線経由・従来の横浜駅経由どちらでも利用可能な定期券の販売などを検討している。

JR東日本は過去に川崎市の貨物線(武蔵野南線)の旅客化構想に多額の追加費用がかかることから難色を示した経緯があった(並走路線として川崎縦貫高速鉄道線が計画されている)が、この計画により貨物線を経由した相鉄との直通を実現させる運びとなった。なお、相鉄・東急直通線の計画は両社ともに公式発表しているが、相鉄・JR直通線の計画については、JR東日本は連絡線の運営主体ではないため、今のところ相鉄側のみが公式発表を行っている(ただしJR東日本が発表した「グループ経営ビジョン2020 -挑む-」12ページ目には相鉄との直通運転を行う旨が僅かながら掲載されている)。

建設の利点

本路線の整備によって、以下のような効果が見込まれている[17]

  • 神奈川県央部・相鉄沿線から新横浜、東京都心への所要時間の短縮。
    • 相鉄沿線からJR線経由で新宿渋谷へは3 - 15分の短縮が、また新横浜や東急線経由の目黒方面への所要時間は15 - 26分の短縮が見込まれている。
  • 相鉄沿線から東京都心方面への乗り換え回数の減少。
  • 相鉄・東急直通線が新横浜駅を経由することにより、新横浜都心や東海道新幹線へのアクセスの大幅な向上。
  • 神奈川県央部 - 東京都心部 - 横浜をつなぐ鉄道ネットワークの形成により、地域間の連携と活性化が図られ、地域の更なる発展に寄与。
