In connection with improvement in the speed of a train, or shortening of attainment time, high deceleration have come to require and the tendency has become strong also by suburbs form train also with many stoppage stations especially at high speed. For this reason, by suburbs form train of the latest inverter control, a large expected adhesion coefficient is taken, highly efficient idling and take-off-run detection equipment are attached, and damage prevention of a wheel is aimed at. However, in respect of maintenance etc., many labors are spent by damage of not only a suburbs form train but a flat, the heat crack of wheel-tread, etc. Then, in this research, it tried to grasp simply the temperature uptrend of idling, take-off run, and wheel-tread by the extraordinary brake with a non-contacting formula radiation thermometer in the vehicles which have a tread brake and the combination of synthetic system composition brake shoe in basic brake equipment. Consequently, in the extraordinary brake, it also checked that the case which wheel-tread temperature rises by 75 degrees C, and roes up by about 25 degrees C in the time of idling when idling speed is about 12 km/h was seen. It proposes that it may become one measurement means of the phenomenon grasp or this simple technique solving the various subjects generated wheel-tread from this.
