Measurement Specifications and Assessment Criteria for Rail Corrugation

Rail corrugation has been a significant problem for the railway industry worldwide for more than one hundred years. Rail corrugation increases the noise levels and wheel /rail interaction vibrations,which causes damage to some components of the track structure and vehicles. Currently the most effective method for controlling corrugation is to grind the rail. As frequent grinding is much expensive,the grinding time interval should be fixed according to the accurate measurement and assessment criteria. In order to support formulating the rail corrugation measurement specifications and assessment criteria for Beijing metro,Euro standards BS EN ISO 3095 : 2005,BS EN 13231- 3 : 2006 and BS EN 13231- 3 : 2006 were referred to by the authors.
