Saitama Rapid Railway Line


The Saitama Railway Line is a mostly underground rapid transit line in Japan operated by the third sector operating company Saitama Railway Corporation. Funded by Saitama Prefecture, local municipal governments, and Tokyo Metro, it forms a continuation of the Tokyo Metro Namboku Line, starting at Akabane-iwabuchi Station in Tokyo and ending at Urawa-Misono Station in Saitama. The line is used as the main means of transportation to Saitama Stadium 2002. On 27 November 2015, the route was nicknamed the "Saitama Stadium Line". The line symbol used in the station numbering is "SR".

Overview

This line allows trains from the Tokyo Metro Namboku Line to operate beyond Akabane-iwabuchi Station into Saitama Prefecture and ending at Urawa-Misono Station.
Most of the line is underground, only Urawa Misono Station and adjacent depots are on the surface. It connects the eastern and northern part of Kawaguchi to Tokyo; areas that were previously only served by buses.
Planning for the line stated in 1972 as an extension of the Tokyo Metro Namboku Line. The original alignment was planned to serve eastern Urawa and central Kawaguchi in Saitama. In 1985, the alignment was shifted east to Hatogaya. In 1992, the third sector Saitama Railway Corporation was established by Saitama Prefecture, and construction began in 1995. The line opened on 28 March 2001, ahead of the 2002 FIFA World Cup, which held several matches at the Saitama Stadium near Urawa-Misono Station.
The total cost of construction is 256.1 billion yen, making the cost per kilometer at 17.5 billion yen. Since its opening, the line used six-car trains with all stations equipped with platforms long enough support future expansion into eight-car trains. Urawa-Misono Station was built as a temporary terminal as the line was planned to be extended further north in the future so it only has platforms long enough for six car trains.
A further northern extension beyond Urawa Misono Station connecting Iwatsuki Station of the Tobu Urban Park Line and Hasuda Station of the JR Utsunomiya Line is currently being proposed.
