The Sendai Subway 1000 series (仙台市交通局1000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 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.
