Superlink was a proposal for a new UK railway network to connect London, the south-east Midlands, East Anglia, and south-east England. It was an alternative proposal from a group of senior railway managers, who played leading roles in other UK rail projects. It suggested changes and enhancements to the Crossrail network. The proponents of Superlink claimed Crossrail gives poor value for money and was unlikely to be built. They suggested that benefits of the Crossrail scheme, including relief of congestion on the public transportation network within London, had been overstated.
