Sir George Young

London Underground estimates that £350 million of its investment backlog relates to civil engineering works on the railway's infrastructure, including tunnels. It does not have a more specific figure for tunnels alone. London Underground has recently completed the refurbishment of the Northern line tunnels under the Thames and has re-lined the tunnels around Old Street station. Work on the Bakerloo and East London line tunnels is well under way.
