A new £12billion cross-London rail scheme linking King’s Cross with Alexandra Palace in the north and Chelsea in the south has been backed by the Mayor of London.

The Crossrail 2 scheme would – if given the go-ahead – run north from Euston and King’s Cross St Pancras to Alexandra Palace, stopping at Angel, Islington; Dalston Junction, Hackney; Seven Sisters, Tottenham and Turnpike Lane.

The new line would also run south, connecting King’s Cross with Tottenham Court Road, Victoria, King’s Road Chelsea, Clapham Junction, Tooting Broadway and Wimblebon, before heading out of the capital to Surrey.

The route has the backing of London Mayor Boris Johnson and if successful, the scheme, suggested by business organisation London First, would begin construction in the 2020s with an opening date in the early 2030s.

A report detailing the proposals was released yesterday (Tuesday, February 5).

London First chairman and former transport secretary, Lord Andrew Adonis, said it set out a “compelling plan with strong business support” and that Crossrail 2 was “essential to keep London moving” as its population rises.

Camden Council said more information on the impact of construction in Somers Town and underground tunnels was needed before giving its full backing to Crossrail 2.

Cllr Phil Jones, cabinet member for sustainability, said: “We would give a cautious welcome to the idea of additional capacity.

“With London growing and the crowded stations we already have, it would be very beneficial to Camden to have that additional public transport.”
