HS2 High-Speed Railway Project

under construction

HS2 is a high-speed railway project in the UK with an expected cost of about £100 billion, including inflation. The project involves construction of tunnels, viaducts, bridges, underground work, and stations such as London Euston and Birmingham Curzon Street. The project is facing rising costs due to increased steel tariffs and energy price shocks from the Iran war. Contractors have procured much of the steel required, and efforts are being made to mitigate future price increases by buying steel in advance. The government is considering options to reduce costs, including slowing train speeds.
