The supply of a cost effective concrete sleeper and rail fastening for the Alice Springs to Darwin railway

This paper describes the technical and logistic challenges of manufacturing and supplying two million concrete monoblock sleepers to the ADrail specifications for this unique project. Following an extensive tendering and evaluation process, ADrail awarded the contract to supply the two million sleepers, complete with the eight million rail fastenings to Austrak Pty Ltd and Pandrol Australia Pty Limited respectively. The contract required a collaborative approach between ADrail and Austrak and hence, Austrak and Pandrol, for the design of the sleeper taking into account the specified operating parameters. Two Austrak sleeper factories were planned, designed, constructed and commissioned—one at Katherine and one at Tennant Creek. Pandrol FASTCLIP system was selected for use on the entire length of the line thus allowing the sleepers to be manufactured with all of the rail fastening components in the rail ready “parked” position, inspected to ensure compliance and stockpiled ready for automated tracklaying. As the majority of the line was specified as non-insulated (non track circuited), the FASTCLIP system was refined to dispense with insulators, but still retain the fully captive features. By adapting the standard FASTCLIP pad, shoulder and clip, a secure non-insulted assembly was developed, which allowed concrete sleepers to be pre-assembled in the factories at Katherine and Tennant Creek and transported, as required, with no component movement or losses.
