Overview

Unlike all other Tokyo subway lines, which were built to 1,435 mm (4 ft 8 1⁄2 in) or 1,067 mm (3 ft 6 in), the Shinjuku line was built with a track gauge of 1,372 mm (4 ft 6 in) to allow through operations onto the Keiō network. The line was planned as Line 10 according to reports of a committee of the former Ministry of Transportation; thus the rarely used official name of the line is the "Number 10 Shinjuku Line" (10号線新宿線, Jū-gō-sen Shinjuku-sen).

According to the Tokyo Metropolitan Bureau of Transportation, as of June 2009 the Shinjuku Line was the third most crowded subway line in Tokyo, at its peak running at 181% capacity between Nishi-ōjima and Sumiyoshi stations.
