The Sendai Subway 1000N series (仙台市交通局1000N系電車) is a rapid transit electric multiple unit (EMU) train type operated on the Sendai Subway Namboku Line in Sendai, Japan.

The 1000 series was the world's first train type to use fuzzy logic to control its speed, and 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] It was the recipient of the 28th Laurel Prize award presented by the Japan Railfan Club.

Refurbishment[]

From 2004 until 2013, the 1000 series trains will undergo mid-life refurbishment to extend their lifespan. As of April 2009, 12 sets have been refurbished,[3] and the refurbished sets are renamed 1000N series.

The refurbished trains include the following features.

  • LED destination indicators at the train ends
  • Space for wheelchairs
  • Air-conditioning
  • LED destination indicators inside trains
