1. A process for measuring the wheel profiles of wheels of a wheelset, comprising the steps of sequentially:
- (a) rotating said wheelset at a speed of at least about 400 revolutions per minute while moving said wheelset at a speed of at least about 45 miles per hour, in order to measure the presence of a high flange or a hollow tread on the wheel profiles of said wheelset,(b) impinging a first wheel of said wheelset with a multiplicity of laser beams to determine the wheel profile of said first wheel,(c) impinging a second wheel of said wheelset with a multiplicity of laser beams to determine the wheel profile of said second wheel, and(d) thereafter, rotating said wheelset at a speed of less than about 75 revolutions per minute while moving said wheelset at a speed of at less than about 6 miles per hour while impinging said wheelset with a multiplicity of laser beams in order to measure the high flange, flange height, flange thickness, rim thickness, wheel diameter, and tread contour on said wheel profiles of said wheelset.

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.
