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.
