History
The Oedo Line began operation on December 10, 1991 (Hikarigaoka to Nerima segment) with the full line in operation on December 12, 2000. An additional station (Shiodome Station) was opened on November 2, 2002 to connect to the Yurikamome guideway transit.
Currently the newest line in the capital, the Ōedo Line is Tokyo's first linear motor metro line, which allows it to use smaller cars and smaller tunnels. These putative cost savings were, however, offset by the need to build the line very deep (as low as 48 meters below ground at points) through central Tokyo, including three underground crossings of the Sumida River. Estimates of the cost of construction range from the official ¥988.6 billion to over ¥1,400 billion yen, making it the most expensive subway line ever built. Ridership figures have been far below the expected 820,000 passengers daily, meaning that the line is unlikely to recoup its costs in 35 years as expected.
Future developments
There are plans to extend the Oedo Line westward from its current western terminus at Hikarigaoka Station through Ōizumi-gakuen Station (on the Seibu Ikebukuro Line) to Higashi-Tokorozawa Station (on the Sobu Line). The first segment to Ōizumi-gakuen is planned to be ready in 2015.
Operation
Image:Tokyo subway map black fixed grey oedo.PNG The Ōedo Line runs in a loop around central Tokyo before branching out towards Nerima in the western suburbs, meaning the line is shaped like a figure of 6 lying on its side. It is not a true loop line: trains from the western Hikarigaoka terminus run anticlockwise around the loop and terminate at the intermediate Tochō-mae Station facing towards Hikarigaoka, and vice-versa.
The terminals and major stations include Hikarigaoka, Roppongi, Daimon, Ryogoku, Iidabashi, and Tocho-mae. Stations on the Toei Ōedo Line carry the letter E followed by a number.
