Abstract: This paper presents a study of requirements management practices on rail transport projects, focusing on the planning and acquisition stages. Linear rail networks are comprised of connected cyber-physical systems. As the transport sector embraces digital twinning in support of more strategic approaches to asset lifecycle management, requirements management functions must also handle a complex of asset information requirements. High levels of integration in complex project environments present significant challenges for requirements management. Using literature and interview surveys, challenges to requirements management practices are investigated. Findings highlight deficiencies in enterprise-wide requirements management methods and tools, with challenges compounded by deficiencies in consistent requirements modelling, common data models, and interoperable toolchains to support continuous, integrated model-based requirements management workflows. Findings identify opportunities to integrate systems and digital engineering functions through alignment of data and processes, and increase systems engineering expertise to improve requirements traceability and change management across system review activities.
