The objective of the program here is to establish an information base which will contribute to the understanding of causes of rail and rail component failure and assist in the development of more effective methods of controlling failures. Current emphasis is on the rail and freight car truck components. Eighteen activities currently underway in component evaluation and inspection are briefly noted and/or described. One of the activities, dealing with rail technology programs for fiscal 1975 involves an in-depth review and analysis of all published works during the past ten years in four specific areas of rail technology: nondestructive inspection, stress/strain measurements and analysis, material failure behaviour, and rail production practices. Among the various concepts of defect and flaw detection, current ultrasonic rail methods are discussed. Information is given concerning an advanced ultrasonic transducer which is being developed to improve sonic detection of vertical split heads and weld defects. The transducer and associated signal processing equipment is intended to be incorporated in an existing rail inspection car for future tests.
