Ōsaki Station
Ōsaki Station (大崎駅, Ōsaki-eki) is a railway station in Shinagawa, Tokyo, Japan, jointly operated by East Japan Railway Company (JR East) and Tokyo Waterfront Area Rapid Transit (TWR).
Lines
Ōsaki Station is served by the following JR East lines.
Saikyō Line
Shōnan-Shinjuku Line
Yamanote Line
It also forms the northern starting point of the TWR Rinkai Line to Shin-Kiba. Most Saikyō Line trains operate through to Shin-Kiba on the Rinkai Line.
Station layout
The station has four island platforms serving eight tracks. Platforms 1 to 4 are for the Yamanote Line, and 5 to 8 are shared by the Saikyō Line, the Shōnan-Shinjuku Line, and the Rinkai Line. Ōsaki is one of the stations on the Yamanote Line loop where trains are put into and taken out of service. It therefore has four tracks (two in each direction) for the Yamanote Line so as not to interfere with continuing trains (trains go several rounds before being taken out). Chest-high platform edge doors were introduced on the Yamanote Line platforms from 22 December 2012.
