This report examines 3 separate track buckle occurrences on the South Island coal route during the summer of 2001/2002. Two of the track buckles resulted in derailments. Safety issues identified by these incidents included: • the need for staff training to ensure they recognise and respond to visible track defects • the need to protect continuous welded rail, formed at unknown neutral temperature • the need to control tamping and lining to ensure track is not realigned leaving increased compressive stress in the rails.
