Hybrid polymer sleepers for TasRail Tasmania’s rugged rail network needs tracks that can withstand the challenging environment. Transport provider TasRail has chosen sleeper materials which use recycled polymers that bond with reinforced steel. With an upgraded, fit-for-purpose rail freight network, TasRail is one of the largest transport service providers in Tasmania, connecting industry and commerce to major shipping ports and freight hubs across the State. The network is a single line, narrow gauge (1067 millimetre) transport system, which has 613 kilometres of operational track including more than 1.3 million railway sleepers. While Tasmania is known for its natural beauty, its climate often provides some challenging conditions for TasRail engineers and operational personnel to deal with, such as including wide temperature ranges, high winds and a corrosive environment. In terms of below rail infrastructure maintenance, TasRail continues to actively look for smarter and more productive ways of ensuring the integrity and safe operation of the network. The effectiveness of the below rail

maintenance strategy continues to improve, with the requirement for unplanned maintenance reducing year on year due to a proactive approach to asset management. As part of this drive for reduced maintenance and to ensure a more sustainable and environmentally friendly network, TasRail has included composite rail sleepers in its network strategy, allowing it to select sleepers that are best suited to the application and which provide an extended life span with the lowest life cycle cost. The availability of good quality timber for sleepers is a known major issue and the life span of timber sleepers has dropped considerably over recent years due to the lack of good quality hard wood. Alternatives had to be considered. Hybrid polymer sleepers fill this gap as they have similar characteristics to timber but have a 50-year life span. These sleepers
are not as rigid as concrete and the load transmitted to the ballast is reduced, creating a very similar track stiffness compared to timber. TasRail has installed composite sleepers previously, but when this contract expired, it elected to issue a new tender to ensure it had the most suitable product on the market. In the first quarter of 2021, TasRail issued the tender to local and international suppliers for the supply of sleepers over a three-to-five-year period for maintenance and capital works. It requested full details to ensure offers met the required technical standards, best product costs, supply chain capability, supply reliability as well as details of the sustainability of the product.
