TheKeio New Line (京王新線,Keiō Shinsen) is a 3.6-kilometer (2.2 mi) link which connectsKeio Corporation'sKeiō Line fromSasazuka Station inShibuya toShinjuku Station with through service on to theShinjuku Line of theTokyo Metropolitan Bureau of Transportation. The line opened on October 30, 1978.
The Keio New Line generally parallels the mainKeio Line along National Route 20 (Kōshū Kaidō) on a deeper route. Except for a short section just beforeSasazuka Station, the entire line is underground.
Because the line was built to normal railway standards and not to subway standards, only specially designed trains can travel along the Keio New Line. However, since new train cars are being designed to be able to operate on above-ground and below-ground tracks there is no real issue with the differentiation. All trains operating west ofSasazuka Station start and arrive at Shinjuku Station. During events at theTokyo Racecourse, there are express trains that operate fromFuchūkeiba-seimommae Station toShinjuku Station.
The Keio New Line shares the same platforms with theToei Shinjuku Line atShinjuku Station. From here trains travel west-southwest. AtHatsudai Station, the westbound platform is two floors underground while the eastbound one is three floors underground. (Both platforms are on the north side of the station.) AtHatagaya Station both platforms are two floors underground with platforms on either side of the two central tracks. From this station, the Keio New line diverges from the Kōshū Kaidō and heads towards the Keio Line further south. The Keiō Line parallels the outside of the New Line on an elevated viaduct over Prefectural Route 420 (Nakano Dori) until Sasazuka Station.
Although there are four types of trains that travel along the Keiō New Line segment (local, rapid, semi express, and express), all trains within the Keiō New Line stop at every station.
