WheelProfileAlignment was written for a railway system that was undertaking routine and detailed monitoring of wheel profiles on several vehicles using commercially available equipment. The software provided with the equipment was appropriate for detailed examination of a few measurements, but difficult to use when examining several measurements either on the same vehicle or of the same wheel over a period of time. With our software it is possible to align up to 10 profiles with a reference profile (which can also be a measured profile) in a variety of ways, calculate the difference between the reference and the measurement, calculate an average profile, output graphs that can be inserted directly into documents or ASCII files for further processing and visualisation. When the alignment procedure or reference profile is changed, all measurements are automatically realigned with a single click of the mouse.

The complementary RailProfileAlignment software has similar capabilities for rail profile measurements.
