Over 130,000 miles of track are tested annually in USA by the Sperry fleet of 25 self-propelled test cars. A new and highly efficient ultrasonic detection system was developed which is capable of finding most cracks and flaws in the joint area. Details are reported. As part of its service Sperry Rail Service has compiled and published a comprehensive manual of rail defects, covering subjects from history and methods of rail manufacture to causes of rail defects and classifications of every known rail defect. This Rail Defect Manual is furnished free to any railway.
