Holborn is a London Underground station in central London. It is served by the Central and Piccadilly lines. Demand for both lines at Holborn is high. The principal design challenges are the close proximity of the proposed tunnels to existing operational tunnels, complex tunnel geometry and alignments, limited clearance to existing buildings, restricted work sites and strict settlement criteria. The lining system is a double shell lining with both linings considered part of the permanent load bearing structure.

Crossrail 2 is a proposed new rail infrastructure project, aiming to alleviate further crowding and congestion across London. The proposed central route will provide a link between Wimbledon in the South and New Southgate and Tottenham Hale in the North with a provision for an Eastern branch towards Hackney Central. It will provide interchange with multiple London underground, London Overground, Crossrail 1, national and international rail services. It is expected to increase significantly the capacity of the regional rail network and reduce the journey times supporting the population growth of the City of London.
