Abstract

With the increasing axle loads and train speeds, the stress limits are being approached for the steels used in the wheels, tires and axles. Described are the various aspects of the work being done to cope with the ever-increasing problems of axle, wheel tread and tire defects and failures. Magnetic particle testing and ultrasonic testing techniques are described, as also the balancing of the wheel sets and the testing of the form stability and strength of the axles. The results of these tests are tabulated.
