during High Speed Running

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.
