Expert rail investigation and design services, offering geotechnical solutions for track foundation and rehabilitation.
Rail Investigation and Design
Our Focus
Hunter Geotechnical Services offers comprehensive rail investigation and design solutions, improving track formation and ensuring the stability of rail infrastructure for freight and passenger systems.
Rail investigation and design are critical components of civil engineering, ensuring the safety, durability, and longevity of rail infrastructure. At Hunter Geotechnical Services, we specialise in providing comprehensive geotechnical investigations and design solutions for rail formation and rehabilitation projects. Our services cater to the unique needs of heavy freight haulage and passenger rail systems in New South Wales, offering cost-effective and sustainable geotechnical solutions to maintain track integrity.
Our rail investigation services are typically conducted during scheduled rail shutdowns or under lookout protection, allowing us to assess soil and rock conditions, sub-surface drainage, and potential causes of track formation failure. Based on these investigations, we provide detailed recommendations for improving or rehabilitating rail track foundations.
Key Rail Investigation and Design Services
- Site Investigation
We conduct thorough site investigations to collect critical data on soil and rock properties, as well as drainage conditions. These investigations are often carried out during rail shutdowns to minimise disruptions. Our team assesses surface and sub-surface conditions to identify any issues contributing to track formation failure, such as weak subgrades or poor drainage. - Track Foundation Design
Based on the site investigation, we provide detailed design recommendations for improving rail track foundations. This includes calculating the California Bearing Ratio (CBR) for the subgrade, determining the required thickness for structural fill and capping layers, and specifying drainage solutions to prevent water accumulation, which can compromise track stability. - Rehabilitation Design
For sections of track that require rehabilitation, we offer both full track formation reconstruction and partial remedial solutions. Full reconstruction may involve rebuilding the track foundation, while partial solutions focus on targeted repairs to address specific issues like drainage or subgrade preparation. Our goal is to provide sustainable and cost-effective solutions tailored to the needs of each project. - Compliance with Rail Authority Requirements
Our services adhere to the standards and guidelines set by the relevant rail authorities in New South Wales. This ensures that all investigations, designs, and rehabilitation works are fully compliant with the safety and performance requirements for heavy freight and passenger rail networks.
Benefits of Rail Investigation and Design
- Improved Track Longevity: Our geotechnical investigations help identify and address potential causes of track formation failure, extending the lifespan of rail infrastructure.
- Cost-Effective Solutions: By offering both full reconstruction and partial remedial options, we provide flexible solutions that suit project budgets while maintaining track safety and stability.
- Regulatory Compliance: We ensure that all designs and rehabilitation works comply with the requirements set by the relevant rail authorities, ensuring safety and regulatory adherence.
- Enhanced Safety: Our investigations and designs ensure that rail track foundations are stable, preventing issues such as subsidence, track movement, or drainage failures.

Frequently Asked Questions
1. What is the purpose of rail investigation and design?
Rail investigation and design services assess the condition of track foundations and provide solutions to improve their stability and durability. This ensures the safe and efficient operation of rail networks, particularly for heavy freight haulage.
2. When is a rail investigation typically conducted?
Rail investigations are often conducted during scheduled rail shutdowns or under lookout protection to minimise disruption to rail operations. These investigations assess soil conditions, drainage issues, and other factors that affect track stability.
3. What is the California Bearing Ratio (CBR) in rail design?
The California Bearing Ratio (CBR) is a measure of the strength of the subgrade beneath the rail track. It is used to determine the required thickness of the structural fill and capping layers needed to support the track foundation.
4. Can you offer partial remedial solutions for track rehabilitation?
Yes, in situations where full reconstruction is not viable, we offer partial remedial solutions that address specific issues, such as improving drainage or stabilising the subgrade, to ensure track safety without the need for complete reconstruction.
