Opis

This volume presents a collection of papers on the theme of rail integrity, which were presented at a meeting in Delft from 24--26th June, 1992. Rolling contact fatigue is a failure mode which is increasingly being recognised as a threat to the reliability of modern heavy freight and high speed railway systems. These papers describe the current understanding of the problem and what rail steel technology and maintenance procedures have to offer to combat it.
