The Sendai City Subway Line (or Sendai City Underground Nanboku Line (仙台市営地下鉄南北線, Sendai shiei chikatetsu nanbokusen) as it is officially known) is a subway line in Sendai, Miyagi Prefecture, Japan. It connects Izumi-chūō Station in Izumi-ku, Sendai, with Tomizawa Station in Taihaku-ku, Sendai. This 1067 mm gauge line is 14.8 km long has 17 stations and runs on 1500 volt underground overhead electric system. The name Nanboku means north-south, which is the general direction that the track runs.
The Nanboku Line was the world's first public train to use fuzzy logic to control its speed, and is often used as an example in university courses on the subject of neural networks. This system (developed by Hitachi)[1] accounts for the relative smoothness of the starts and stops when compared to other trains, and is 10% more energy efficient than human-controlled acceleration[2].
