Abstract
A process for accurately and automatically measuring the properties of wheelset profiles while the wheelsets are in normal operation. In the first step of the process, the wheelset is rotated at a speed of at least 400 revolutions per minute while moved at a speed of at least 45 miles per hour, and a laser detection system is used to measure the profile of both wheels of the wheelset. In the second step of the process, the wheelset is rotated at a speed of less than 75 revolutions per minute while moved at a speed of less 6 miles per hour while its wheel profile properties are evaluated by a laser detection system.
