TheToei Subway(Đô 営 địa hạ thiết,Toei chikatetsu,lit. 'metropolis-operated subway')is one of two subway systems inTokyo,the other beingTokyo Metro.The Toei Subway lines were originally licensed to the Teito Rapid Transit Authority (the predecessor of Tokyo Metro) but were constructed by theTokyo Metropolitan Governmentfollowing transfers of the licenses for each line. The subway has run at a financial loss for most of its history due to high construction expenses, particularly for theOedo Line.However, it reported its first net profit of ¥3.13bn in FY2006. The Toei Subway is operated by theTokyo Metropolitan Bureau of Transportation.

Tokyo Metro and Toei trains form completely separate networks. While users of prepaid rail passes can freely interchange between the two networks, regular ticket holders must purchase a second ticket, or a special transfer ticket, to change from a Toei line to a Tokyo Metro line and vice versa. The sole exceptions are on the segment of the Toei Mita Line between Meguro and Shirokane-Takanawa, where the platforms are shared with theTokyo Metro Namboku Line,and atKudanshitaon the Shinjuku Line, where the platform is shared with theTokyo Metro Hanzomon Line.At these stations, it is possible to change between the networks without passing through a ticket gate.

Branding

Apart from its own logo, a stylizedginkgoleaf used asthe symbol of the Tokyo Metropolis,Toei Subway shares a design language in common with Tokyo Metro. Lines are indicated by a letter inFutura Boldon a white background inside a roundel in the line color, with signs indicating stations adding the station number as well. Line colors and letter-designations are complementary with Tokyo Metro's, with none overlapping (e.g., the Mita Line's letter-designation is “I”, rather than “M”, which is used by theTokyo Metro Marunouchi Line). Informational signage is also designed identically, with platform-level station placards differing only in the placement of the bands in the line color: Toei Subway has two thin bands at the top and bottom, while Tokyo Metro has one wider band at the bottom (or, in the case of long, narrow placards, in a continuous band extending to the left and right along the wall itself).

Lines

The Toei Subway is made up of four lines operating on 109.0 kilometers (67.7 mi) of route.

Two of the lines have different colors for their station signs: Asakusa (VermilionA) and Shinjuku (LimeS). The Ōedo Line formerly had a darker magenta (O) as its designated color.

Through services to other lines

The different gauges of the Toei lines arose in part due to the need to accommodate through services with private suburban railway lines. Through services currently in regular operation include:
