RailMeasurement increases awareness of wheel/rail noise, roughness and corrugation

Posted by RailMeasurement on 3 May 2011

In May 2011, Dr Grassie was a member of a panel on wheel/rail noise at the Rail Transit seminar organised by ARM Corporation in Chicago.  His presentation on wheel/rail noise, rail grinding, measurement and specifications can be found here.  This contains several sets of measurements of rail corrugation and acoustic roughness made with RML’s CAT and RCA on different types of track worldwide, before and after reprofiling.
