Toei Subway

The Toei Subway is a rapid transit system operated by the Tokyo Metropolitan Bureau of Transportation, a bureau of the Tokyo Metropolitan Government that focuses on transportation.
Originally, the lines were licensed to the Teito Rapid Transit Authority but were constructed by the Tokyo Metropolitan Government after transferring licenses; the company has actually run at a financial loss for most of its existence due to high construction costs, but reported its first gain in 2006.
The Toei Subway is rather unique among most subway systems in that it uses three gauges. The Asakusa and Ōedo Lines use 4 ft 8½ in (1,435 mm) rails, the Mita Line uses 3 ft 6 in (1,067 mm) rails while the Shinjuku Line uses 4 ft 6 in (1,372 mm) rails.
The Tokyo Metropolitan Bureau of Transportation also owns the Tokyo Toden streetcar network.
