Onboard friction control cuts noise and vibration
By Railway Gazette International and Kosuke Matsumoto, Masao Tomeoka, Yoshihiro Suda, Takuji Nakai, and Masuhisa Tani2006-09-01T10:00:00
Bogie performance through curves can be improved by careful control of the friction between wheel and rail. A group of Japanese engineers has developed a friction control method for the Tokyo Metro using an onboard rail spray to control the friction coefficient and the friction characteristics of the wheel-rail contact ...
