Abstract
This paper investigated the failure of a rail that had been in service for approximately 25 years in
Tasmania, Australia. A segment of the rail was taken from the site on a curved railway track. From its
service history, it was found that the maximum train speed over that period was around 35km/h.
However, approximately one third of the movements were at a speed less than 20km/h due to the fact
that the rail was located on the steepest section of the line. Visual examination on the rail sample
revealed that the rail had experienced mixed traffic conditions during the service history.
Mushrooming shaped plastic flow occurred in the railhead. The chemical composition of the rail was
analysed using the optical emission spectroscopy method. Metallurgical observation on the rail sample
and a hardness test were conducted, aiming to investigate the root cause of the failure. The aim of this
study was to conduct the failure analysis of the rail and to provide knowledge regarding the selection
of a sustainable type of rail for this application.
