History
Nakanobu Station is an interchange in Shinagawa, Tokyo, served by the Tōkyū Ōimachi Line above ground and the Toei Asakusa Line below it. The Tōkyū platforms opened on 6 July 1927 with the Meguro-Kamata Electric Railway's Ōimachi Line, originally at ground level on opposed platforms. Elevation work began in July 1954 and finished on 11 July 1957, lifting 1.02 km of track onto a new viaduct and closing nine level crossings. The underground Toei station opened on 15 November 1968 as a stop on the then Toei Line 1, which was renamed the Asakusa Line on 1 July 1978. The station is OM04 on the Tōkyū side and A-03 on the Toei side.

Notes
The 1950s elevation project carved the Tōkyū tracks up onto a brand-new viaduct and embankment north of the original alignment, erasing nine level crossings along the 1.02-kilometre stretch between Ebaramachi and Togoshi-Kōen.
