A new steel rail sleeper system has been installed on the Leonara to Kalgoorlie line in Western Australia to deliver cost benefits over the lifespan of the infrastructure.
The line is undergoing $2.3 million of improvements, including the replacement of more than 6,000 sleepers and upgrade of 2,400 sleeper plates.
Arc Infrastructure is delivering the upgrade and said the sleepers are delivered with all fastenings attached as one unit to reduce the number of steps required to install them.
It expects the new style of sleeper would outperform traditional steel sleepers, as well as timber sleepers, due to reliability improvements and a longer life cycle.
Arc Infrastructure Head of Network Strategy and Long Term Planning, Michal Golinski, said the company was the first in Australia to use this type of steel sleeper.
- Recycled railway sleepers installed in major Melbourne station
- Could recycled plastic be a viable alternative for timber railway sleepers?
- Metro Trains to support recycled glass in level crossings
“This particular sleeper system is expected to out-perform traditional steel and timber sleepers due to a longer design life and improved reliability,” he said.
“Arc Infrastructure will assess the performance of the steel sleeper over future years, and will continue to fine tune processes to better optimise the performance of the sleeper and track.
“These works are part of Arc Infrastructure’s ongoing major maintenance program and are critical to providing a safe, efficient and reliable freight network.”
The sleepers are also recyclable once they reach the end of their usable life, able to be turned into new steel products.
