摘要: Abstract Rail grinding is a typical maintenance procedure for railways in which an abrasive wheel used to restore the rail profile while eliminating defects such as corrugation, fatigue cracks and detachment marks. In this work, procedures performed during 10 years 22 curves of commercial railway (Metro de Medellin railway, line B) were studied classified understand most important causes damage. Periodical inspections done identify main wear mechanisms field into loss profile. The results showed that corrugation took place preferentially on low was observed high rail.
