Through Operation

Tokyo Metro Fukutoshin Line

On 16 March 2013, the section of the Toyoko line between Shibuya and Daikanyama Station was put underground, and connected to the Tokyo Metro Fukutoshin Line platforms at Shibuya. This allows for through operation between the two lines. Since opening of the Fukutoshin Line in 2008 trains would through operate between the Seibu Ikebukuro line (via Seibu Yurakucho line) and the Tobu Tojo line at the northern end of the Fukutoshin Line. The new connection allows trains from Tobu Railway, Seibu Railway, Tokyo Metro, Tokyu Corporation and Yokohama Minatomirai Railway to operate trains in a common corridor. As a result of the new connection, the original elevated Shibuya terminal for Tokyu trains was abandoned and demolished.

Minatomirai Line

On 1 February 2004, Toyoko line was realigned underground between Tammachi and Yokohama Station to enable through services with the Minatomirai Line. The original alignment to Yokohama Station was demolished and turned into a rail trail.

Tokyo Metro Hibiya Line

Through operation with the Tokyo Metro Hibiya Line started on 29 August 1964, with trains starting at Hiyoshi station will travel into Kita-Senju Station via a connection to the Hibiya Line at Naka-Meguro Station. In 1988, this service was extended to Kikuna Station temporarily during the realignment of Hiyoshi station to an underground corridor, but was retained as official service due to its popularity. With the start of through operation with the Fukutoshin Line services, all through services between the Toyoko Line and the Hibiya Line were abolished. Passengers needing to transfer between the two lines have to perform a cross-platform interchange between the two lines at Naka-Meguro Station.

Sagami Railway (Planned)

In May 2006, both the Tokyu and Sagami Railway (Sotetsu) announced a plan to build a 12.7 kilometer long connection to allow through services between the Sagami Railway Main Line and Toyoko Line. The connection is envisioned to start at Hiyoshi Station and head to Sōtetsu Main Line's Nishiya Station. New stations will be set up at Tsunashima Station, Shin-Yokohama Station and Hazawa Yokohama Kokudai Station. However, when a concrete plan was specified in November 2008 for Tsunashima station, the plan was changed to the establishment of a "Shin Tsunashima Station" to be constructed near Tsunashima station.

    History
    Toyoko Line train in 1980

    The first section of the line from Tamagawa to Kanagawa (separate from the present Kanagawa of Keikyu) opened on 14 February 1926. The line was extended incrementally until the entire length from Shibuya to Sakuragichō in Yokohama was opened on 31 March 1932. On 29 August 1964, through service to the Tokyo Metro Hibiya Line via Naka-Meguro Station was started.[4]

    The former Sakuragicho Station platforms in January 2004

    On 31 January 2004, the section of Yokohama to Sakuragichō was abandoned.[4] From 1 February, Tokyu Toyoko Line trains started through service from Yokohama to the Minatomirai Line.[4]

    On 16 March 2013, the 1.4-kilometer section between Shibuya to Daikan-yama was replaced with an underground connection to the Tokyo Metro Fukutoshin Line. The original ground-level terminal platforms were closed after the last service at 1 am that morning.[5] Just four hours later, at 5 am, trains began calling at a new set of underground platforms adjacent to those previously served only by the Fukutoshin Line.[6] During this time, 1,200 workers shifted the track alignment at Daikan-yama Station along a pre-built incline.[7] Since that day, Tokyu and Yokohama Minatomirai Railway trains commenced through running onto the Fukutoshin Line and beyond. Tokyo Metro, Tobu, and Seibu also started operating their trains through to the Toyoko and Minatomirai Lines. At the same time, through service on Hibiya Line ended.

    Incidents and accidents

    On 15 February 2014, two trains collided and derailed at Motosumiyoshi station resulting in nineteen injuries.[8] Heavy snow and operations continuing at normal speed were seen as likely causes.[9]

    Future developments

    Platform edge doors are scheduled to be installed at all stations on the line by 2020.[10]
