Sendai subway
The Sendai subway ( Japanese 仙台 市 営 地下 鉄 , Sendai-shiei chikatetsu , dt. Sendai urban subway ) is the subway network of the Japanese city of Sendai . It currently consists of two lines operated by the Sendai City Transport Office ( 仙台 市 交通局 , Sendai-shi Kōtsū Kyoku ). The first plans for the construction of the subway had already been made in 1965, but construction of the first line did not start until 1983.

The individual wagons are inspected every three days and intensively checked every three months using automatic test equipment. In-depth maintenance takes place every three years. The innovative train control system developed by Hitachi using fuzzy logic received particular attention from experts . Starting, accelerating and braking processes are carried out fully automatically, so that the train moves smoothly and both a great gain in comfort and energy savings are achieved.
Namboku line
Line 1, called Namboku Line (dt. South-North Line), runs from Izumi-Chūō in the north via the city center to the southern suburbs. The total length is 15 km (12 km of which run in the tunnel) with a total of 17 stations (14 of them in the tunnel). Operations began on July 15, 1987.
The length of the platforms is 130 m and the track width of the tracks is 1,067 mm ( cape gauge ). Four wagons make up a train. Power is supplied via an overhead line with 1500 V DC voltage . The operating hours are from 5:45 a.m. to 11:45 p.m., the frequency of journeys is between 4 and 6 minutes. All stations are wheelchair accessible with elevators (also labeled in Braille ). The appearance of the stations is tailored to the respective environment, e.g. B. with artistic wall and ceiling painting. In the two wagons at the ends of the train there are special benches reserved for pregnant women , elderly or disabled people.
Tōzai line
Another route, Line 2 or Tōzai Line (German East-West Line), was opened on December 6, 2015 after eleven years of construction.
It runs completely underground from Yagiyama-Dōbutsu-kōen in the west to Arai in the east. The line is 13.9 km long and has 13 stations, the gauge is 1435 mm ( standard gauge ). As with comparable newer subway routes in Tokyo ( Ōedo line ), Kobe (Kaigan) or Ōsaka (Nagahori-Ryokuchi), the drive is via a linear motor .
