The government says the HS2 high-speed rail project is now expected to cost up to £102.7 billion and that trains on the London–Birmingham section will not begin running until as late as 2039. Transport Secretary Heidi Alexander makes clear that the timetable and budget have moved further from earlier promises, with construction completion for the remaining scheme running until as late as 2043. One report says the announcement will also include further budget detail set out for 2026 prices, with plans for operational changes intended to manage costs. While backers hope the updated costings could be kept substantially below £100 billion in 2026-price terms, other reporting highlights that the overall figure in nominal terms is much higher. Additional scrutiny is raised by commentators who argue the published figures may exclude inflation, suggesting the “real” total could be higher. Overall, the accounts agree that HS2 faces both significant cost growth and major delays, alongside a reduced scope compared with the originally planned line.
