The CAT (Corrugation Analysis Trolley) is an extremely accurate instrument that is used to measure rail for acoustics purposes and for Quality Assurance of rail grinding. It has the great attraction that it can be both used and carried by a single person: the equipment, when packed in a convenient box (supplied), weighs less than 15kg. There are few, if any, instruments that can measure extended sections of rail with similar accuracy and no others, to our knowledge, which can be used conveniently by a single person.
- The CAT is widely regarded as THE accepted method of measuring rail corrugation.
- An industry-standard notebook PC is used for data acquisition and analysis.
- CAT measurements showing sporadically severe corrugation in the 100-300mm wavelength range, that has been reduced by grinding to within the requirements of EN I3231-3:2006.
