The Transport Secretary is expected to announce further delays and higher costs for the beleaguered HS2 project on Tuesday, as the high-speed link is set to become the most expensive rail line in the world.

Heidi Alexander is due to set out a new timetable for the heavily stripped back rail link between London and Birmingham, with cost estimates likely to come in around £100bn – or £1bn per mile.

For comparison, Nasa’s Artemis II mission to send astronauts back to the Moon, which in April saw the first manned orbit around the Moon in 50 years, cost less, coming in at around an estimated $93bn or just under £70bn spend, between 2012 and 2025.

The total estimated cost projected for 2028, when Nasa is hoping to land astronauts on the Moon, is $105bn or £79bn.
