Future of Rail: DfT Awards Rail Infrastructure Advisory Contract

Costain Consortium Awarded Rail Infrastructure Advisory Contract by Department for Transport

The Department for Transport (DfT) has awarded a contract to a consortium led by Costain, with support from GHD, to provide expert technical and commercial advice on rail infrastructure projects across the Western, Wales, and Wessex regions. The two-year contract, commencing April 2025, will see the consortium—including specialist partners InteGen, North Star, and SLC Rail—deliver economic analysis, technical expertise, and strategic guidance to the DfT. This initiative aims to enhance the resilience and operational performance of rail infrastructure and services across the aforementioned regions. The DfT’s selection follows on from GHD and Costain’s previous work on the Specialist Technical and Commercial Advice for Rail and Other Transport Modes (STARThree) Framework. The primary objective is to optimise rail infrastructure investments and operational efficiency through comprehensive advisory services.

Comprehensive Advisory Services

The consortium’s remit extends to providing comprehensive advisory services to the DfT. This includes working closely with Network Rail and train operators to evaluate project proposals, investment cases, and strategic plans. This collaboration ensures a holistic approach to rail infrastructure enhancements. The consortium will undertake detailed assessments related to timetable modelling, rolling stock requirements, and depot and stabling arrangements. This encompasses a deep dive into the operational realities and logistical intricacies required for successful rail operations. This is all essential for achieving optimised performance and efficient resource allocation, ensuring railway projects meet the demands of modern transportation needs.

Climate Change Resilience and Adaptation

A critical aspect of the contract involves assessing the impact of climate change on railway infrastructure. This includes a detailed examination of geotechnical behaviour, the risks associated with flooding, and other climate-related challenges. This research will provide crucial insights into the resilience of rail networks against the effects of climate change. The team will utilise innovative analytical techniques to predict potential vulnerabilities, enabling the DfT to proactively develop adaptation strategies and mitigation measures. The aim is to ensure the long-term viability and operational integrity of rail infrastructure amidst a changing climate. This is critical for the industry as a whole and for the UK’s commitment to reducing emissions in the transport sector.

Extending Existing Collaboration and Expertise

This contract represents an extension of the existing relationship between the DfT and the consortium members, particularly GHD and Costain. Huw Kane, Service Group Manager for Rail at GHD, highlighted the extended partnership, emphasizing the team’s established track record of delivering “whole railway, whole system technical advice”. This continuity in working relationships, combined with the consortium’s extensive experience, promises to bring significant value to the Western, Wales and Wessex portfolios. The consortium’s approach is focused on providing efficient and economic solutions, which ultimately enhance transport choices for communities and supports the long-term sustainability of the rail network.

Conclusion

The awarding of this contract underscores the DfT’s commitment to proactive infrastructure management and the importance of expert technical advice in ensuring the reliability, efficiency, and resilience of the UK’s rail network. The consortium, led by Costain and backed by GHD and its partners, is well-positioned to support the DfT in navigating the complex challenges of modern rail infrastructure management. The emphasis on climate change resilience highlights a key priority for the industry, reflecting the increasing need to adapt infrastructure to the impacts of a changing climate and to build more sustainable and adaptable rail systems. By leveraging their collective expertise and collaborative approach, the consortium aims to drive innovative solutions and enhance operational performance. This project sets a benchmark for collaborative efforts in the rail sector, ensuring long-term success and improved service for passengers and freight transport.
