To prevent wheel slips and wheel slides of trains, a particle jetting device has been installed as a type of sanding devices. In this device, the adhesion between wheels and rails is increased by jetting ceramic particles between wheels and rails. In the previous paper, a monitoring system of particle flow in the device was proposed, and the performance of the system was verified through the bench test. The assured actuation of the device is indispensable to the safe operation of high speed vehicles. It is very important to verify the performance of the developed system through real operating conditions of trains. From that viewpoint, the results of running tests at several types of trains and several types of operating conditions are analyzed in this manuscript. The vibration of the particle jetting device affects the monitoring performance because the proposed system detects the particle flow by measuring the static electricity of flowing particles in a tube. Thus, the vibration at real operating condition was measured using accelerometer installed in the bogie frame. The results of test runs showed that the proposed monitoring system functions well at every condition and has high possibility to apply real operations.
