Abstract
Railway Systems Integration is a critical aspect of delivering functional, reliable railway systems. It involves not just the technical alignment of complex subsystems – such as signalling, rolling stock, and infrastructure – but also the incorporation of operational, maintenance, and organisational elements to ensure that the railway system operates effectively and meets its intended benefits. The paper examines five themes – responsibility, complexity, staged delivery, scope, and stakeholders – drawing insights from major infrastructure and upgrade programmes, such as the London Underground Jubilee Line Extension and Crossrail.
