Crossrail is a £14.8bn project aimed at enhancing London's transport infrastructure through 118 km of new rail lines and 40 stations, enabling 200 million journeys annually. The governance model emphasizes accountability, transparency, and effective risk management, with a hybrid structure involving both central and local government. The project has been able to maintain funding continuity, timely decision-making, and is expected to be completed on schedule and within budget, with plans for Crossrail 2 following a similar governance framework.
