| The Shinjuku Line is one of two main lines of the Seibu Railway system along with the Ikebukuro Line. The two main lines cross at Tokorozawa Station in Tokorozawa, Saitama. The line serves the western suburbs of Tokyo, connecting them to Shinjuku and other areas of downtown Tokyo.
The line is mostly double-track, except for 1.1 km of single track between Wakita Junction and Hon-Kawagoe Station. While the section from Seibu-Shinjuku to Takadanobaba is elevated, the line runs at ground level through a suburban area until Saginomiya. |
