A new method to improve the adhesion between wheel and rail with ceramics particles has been developed. In this method, a small amount of ceramics particles required is jetted with compressed air between wheels and rails with high speed, high efficiency and high response. The skid in time of braking and slip in time of powering during high speed running are almost stopped with an amount of 0.3 mm ceramics particles which is less than in the traditional sanding. This paper gives an outline of this new method with results of some field tests.
