Rail Network Renewals Engineering Services Provider
Engaged by Rio Tinto Iron Ore’s Rail Network Renewals (RNR) team in 2025, our team has delivered a program of study and design phases to support ongoing renewal works across the Pilbara heavy haul rail network. These services have focused on maintaining and restoring safe, reliable track performance while aligning with planned production requirements and operational constraints.
What differentiates this program of works is our team’s ability to deliver practical, value-driven outcomes through:
- Optimised capital expenditure, by adopting a data-driven approach that integrates IOC outputs, track maintenance history trends, and targeted geotechnical field investigations to develop fit-for-purpose renewal solutions and avoid overdesign.
- Strong local knowledge supported by deep heavy haul rail technical expertise. Our team brings extensive Pilbara experience across the design, construction, and asset management of heavy haul rail, ensuring design decisions are practical, risk-informed, and tailored to local constructability constraints and delivery practices.
- Adaptability to complex and inherited datasets, efficiently identifying and resolving inconsistencies and gaps in legacy survey, geometry, and asset data to establish a reliable design basis and maintain program momentum.
- Collaborative design development environment, by facilitating open design working sessions and discussion with client stakeholders to align on constraints, validate assumptions, and accelerate decision-making.
The track and civil-led team are supported by specialist disciplines including advisory, data analytics, hydrology, geotechnical, and structures to deliver the following key project elements:
- Track renewal design
- Ballast and formation renewal treatment design
- Major renewals – culvert replacements
- Rail alignment studies
- Construction-enabling works civil design
- Strategic laydown and temporary facilities design
- Utilities impact assessment & construction decision making framework for works near fibre optic telecommunications services
- Hydrology and flood risk assessment
- Rail supporting infrastructure upgrades, including rail access roads and floodways
- Geotechnical site investigation and inspections
This program of works reflects our ability to deliver integrated infrastructure design that meets client goals, regulatory standards, and operational needs while driving capital value at every stage.
“At Agilitus, our point of difference lies in the approach to fit for purpose design informed by our deep understanding across the full life cycle of heavy haul rail. Our design is informed by real world operational rail experience from our team who are routinely involved with predictive asset management for major heavy haul rail operators across Australia on a range of greenfields and brownfields projects.
Our design is led by senior technical specialists who apply experienced engineering judgement in the delivery of pragmatic, delivery focused solutions. This approach is shaped by decades of experience on some of Australia’s largest and most complex rail and mining infrastructure projects. Our expertise is multidisciplinary and integrated covering geotechnical, civil, hydrology, structural and systems engineering into a single coordinated service. This ensures that design decisions are supported from constructability, operational efficiency, long term resilience and whole of life value perspectives.”
