John McLeod, Professional Head of Track Engineering at Sydney Trains and Prof. Huijun Li from the University of Wollongong will present their research into crack propagation and squat growth in rails and discuss the impacts for the rail industry in the treatment and prevention of squat defects.

Evolution of rail surface degradation in the tunnel

Evolution of rail surface degradation in the tunnel The role of water on squat growth under service conditions Theoretical research hypothesises that the hydraulic entrapment of water is critical to crack propagation associated with squat growth. This explains why squats do not occur in track inside tunnels. However, metallurgical evidence from ex-service rails damaged by the presence of water at the wheel and rail interface is lacking. A localised section of rail was discovered to have suffered severe surface damage as a result of water dripping from an air-conditioning system located in the tunnel roof. This section of rail offered an ideal controlled location for a detailed metallurgical investigation of the formation of white etching layers (WELs) under both dry and wet conditions. The study would also examine the relationship between WELs and squat initiation and the mechanics of water on crack propagation and squat growth of ex-service rail. This presentation will reveal some of the surprising evidence gathered during this study and discuss the potential impacts for the rail industry in the treatment and prevention of squat defects.



Technical-Networking Meeting Sponsorship

Sponsorship opportunities for the Technical Meetings are opened and sought from the AGM in August each year. Alternatively companies can make a nomination to sponsor a meeting by emailing the PWI meetings sub-committee on meetings@pwinsw.org.au

Sponsorship of 2019 Technical Meetings will be opened at the 2018 AGM (16th August).
