In order to realize constant monitoring of wheel/rail contact forces, a new measuring method has been developed that needs no 'special wheelset'. The new method uses non-contact gap sensors for measuring of the lateral contact force. The lateral distortion of the wheel rim or web is measured by a non-contact gap sensor, and after the compensation by the data from other gap sensors, the lateral contact force is obtained. After curve running tests on a test stand and train running tests on a commercial line, it has been verified that this new method can obtain sufficient data for practical use. But further improvement should be necessary for higher accuracy in inside wheels. The normal contact force is measured by the strain of the truck frame, and the longitudinal contact force is measured by the strain of the lever of axle-box support link. Both methods can obtain the sufficient accuracy of data for practical use.
