The Tokyo Metro Namboku Line (東京メトロ南北線, Tōkyō Metoro Nanboku-sen, South-North Line) is a subway line owned and operated by Tokyo Metro in Tokyo, Japan. The line runs between Meguro in Shinagawa and Akabane-Iwabuchi in Kita. The Namboku Line was referred to as Line 7 during the planning stages, thus the seldom-used official name is Line 7 Namboku Line (7号線南北線, Nana-gō-sen Nanboku-sen).

On maps, diagrams and signboards, the line is shown using the color emerald (previously coded "teal"), and its stations are given numbers using the letter "N".

Overview

[edit]

Trains run through onto the Tokyu Meguro Line for ‹See TfM›Hiyoshi and the Saitama Railway's Saitama Rapid Railway Line (which is essentially a separately-owned extension of the Namboku Line) for ‹See TfM›Urawa-Misono.

The right-of-way and stations between ‹See TfM›Shirokane-Takanawa and Meguro are shared with the Toei Mita Line – a unique situation on the Tokyo subway where both operators share common infrastructure. Under an agreement between Tokyo Metro and the Tokyo Metropolitan Government, the fare for this section is calculated on the Toei fare system for passengers traveling to stations on the Mita Line past Shirokane-Takanawa, on the Metro fare system for passengers traveling to stations on the Namboku Line past Shirokane-Takanawa, and on the system "most beneficial to the passenger" (presently the Metro schedule) for travel solely on the shared sector.

On maps, diagrams and signboards, the Namboku Line is shown using the color emerald (), and its stations are given numbers using the letter "N".

History

[edit]

The 21.3 km (13.2 mi) Namboku Line is one of Tokyo Metro's newer lines, featuring advanced technology including full automatic train operation and platform screen doors. Although the line was originally proposed in 1968, construction did not begin until the 1980s, partly due to the right-of-way to Meguro with the Toei Mita Line. The first segment from ‹See TfM›Komagome to ‹See TfM›Akabane-Iwabuchi opened on 29 November 1991.

The line initially operated with four-car EMUs. Upon its extension to Yotsuya in March 1996, the formations were extended to six cars. On 1 April 2022, eight-car trains began operating on the line.[2]

The extension to ‹See TfM›Tameike-Sannō was completed in September 1997, and the last stretch from Tameike-Sanno to Meguro was completed on 26 September 2000, when through service to the Tokyu Meguro Line started.[3] Through service with the Saitama Rapid Railway Line commenced when it opened in March 2001 and accommodated traffic to and from Saitama Stadium during the 2002 World Cup. Although the Saitama Line is more or less a northern extension of the Namboku Line, it nevertheless remains a private entity to which the Namboku Line offers through services with.

The Namboku Line was inherited by Tokyo Metro after the privatization of the Teito Rapid Transit Authority (TRTA) in 2004.[4]

Effective the timetable revision on 18 March 2023, through services onto the Sagami Railway commenced courtesy of the Tokyu and Sotetsu Shin-Yokohama Line.[5] Most southbound services past Hiyoshi continue as far south as Shin-Yokohama and Ebina.

Future plans

[edit]

On 28 January 2022, Tokyo Metro announced that a 2.5 km (1.6 mi) spur line from Shirokane-takanawa to Shinagawa would be built.[6] The extension is expected to cost ¥131 billion (2021) (US$1.19 billion) and scheduled to begin revenue service in the mid-2030s. It is intended to increase connections to and from the Chūō Shinkansen, which is scheduled to open for service in 2027.
