HS2 Review Blames High-Speed Ambitions and Political Pressure for Project Problems

A major review into the troubled HS2 rail project is expected to conclude that unrealistic ambitions, political interference and poor early decision-making played a significant role in the scheme’s ongoing difficulties.

The report, led by former National Security Adviser Sir Stephen Lovegrove, reportedly identifies several “original sins” at the heart of the project, including the decision to prioritise extremely high operating speeds and push ahead with construction before designs were sufficiently developed.

HS2 was originally engineered to support train speeds of up to 360km/h (224mph), although ministers are now considering reducing the maximum speed to around 320km/h (199mph) as part of wider efforts to control costs and reassess the programme.

Transport Secretary Heidi Alexander is expected to provide an update on revised budgets and delivery schedules this week.

According to Lovegrove’s findings, the project became overly focused on creating what was described as the “world’s best railway”, leading to complex and highly customised engineering solutions that increased risk and expense.

The report is also expected to criticise the decision to begin construction on some of the most technically difficult sections of the route first, particularly Phase One between London and the West Midlands.

Lovegrove reportedly found that shifting political priorities created confusion throughout the programme. While HS2 was promoted as a transformational national rail project, there was also constant pressure to deliver it within strict financial and timetable expectations.

He stated that ministers repeatedly pushed organisations involved in the scheme to maintain momentum, creating an environment where concerns over cost, risk and readiness were not always fully addressed.

The review also suggests that major contracts were awarded before designs had reached an adequate level of maturity. As a result, risks were not properly managed and both costs and complexity were significantly underestimated from the outset.

Cost forecasts for the railway have since risen dramatically, with previous reviews already highlighting serious weaknesses in financial planning and governance.

Earlier suggestions that reducing HS2’s top speed could generate savings have been challenged by several rail experts, who argue that changes at this stage may actually increase costs rather than reduce them.

Rail consultant William Barter questioned where meaningful savings could realistically be achieved given the scale of construction already completed. He warned that altering elements such as track design could reduce long-term efficiency and increase maintenance and operating costs in the future.

Barter also argued that slower train speeds could require additional rolling stock and larger train crews to maintain service levels.

Railway engineer Gareth Dennis echoed those concerns, saying the best financial option now would be to stabilise the project rather than continue making changes. He argued that redesigning the scheme after years of development risks creating further delays and extra costs while reducing some of the wider network benefits HS2 was intended to deliver.

Senior HS2 officials, including chief executive Mark Wild, Rail Minister Lord Hendy and Department for Transport representatives, are expected to appear before the Transport Select Committee to discuss the project’s future and ongoing reset programme.

Wild recently stated that the latest restructuring effort is intended to provide a stable long-term delivery plan and avoid further major revisions.

Meanwhile, HS2 Ltd recently awarded an £856 million contract for the construction of the Washwood Heath Rolling Stock Depot and Network Integrated Control Centre to a joint venture involving Taylor Woodrow and Aureos Ltd.

The project is expected to become an early example of the revised delivery approach being adopted under the HS2 reset strategy. Construction at the site is currently expected to begin in 2028, aligning with the planned development timetable for the future HS2 train fleet.
