Measuring microns at 50km/h

Posted by RailMeasurement on 13 May 2011

In May 2011, comprehensive testing was undertaken of RML’s hi-rail based MSRCA corrugation system, which is designed to measure corrugation to an accuracy of microns at speeds of up to 50km/h.  Correlation of MSRCA at 50km/h with CAT measurements (moving average of RMS amplitude in 30-100mm wavelength range, percentage exceedence graph and one-third-octave spectra) over 500m of rail is shown below.   Correlation is very impressive.

MSRCA data from 50km/h run correlates well with CAT data
