Work continues at the Old Oak Common Station construction site for the HS2 high-speed 2 railway project, in north west London on September 29, 2023. HS2, the UK's second high-speed train line after the one leading to the Channel Tunnel, has suffered spiralling costs despite the route being cut short, raising fears the project could be further derailed. Designed to bring the major cities in the north of England closer to London, its cost was estimated at Ł37.5 billion ($46 billion) in 2013. (Photo by HENRY NICHOLLS / AFP)
