Northern Powerhouse Rail Faces HS2-Style Risks, Warns Public Accounts Committee

The future of Northern Powerhouse Rail (NPR) could be jeopardised by many of the same issues that affected HS2 unless stronger governance, clearer planning and tighter financial controls are introduced, according to a new report from the Public Accounts Committee (PAC).

The cross-party committee has warned that while Northern Powerhouse Rail remains one of the UK's most important transport infrastructure projects, significant questions remain over its scope, delivery strategy and ability to stay within the government's £45 billion funding cap.

More than a decade after the scheme was first proposed, MPs argue that key decisions on routes, capacity, governance and delivery have yet to be finalised. They believe this creates a genuine risk that the project could experience the same cost overruns and delays that have impacted HS2.

The PAC has criticised the Department for Transport (DfT) for failing to demonstrate how Northern Powerhouse Rail can realistically be delivered within budget when large sections of the proposed railway have not yet been fully designed or costed.

Clive Betts MP, Deputy Chair of the Public Accounts Committee, said there were "troubling echoes" of the governance issues that emerged during the early stages of HS2. He questioned how the government had arrived at a fixed £45 billion funding limit before the project's full scope had been established, describing it as "putting a roof on a house before the foundations are even laid."

One of the committee's main concerns centres on how the funding cap was calculated. Without detailed engineering designs and robust cost estimates, MPs believe there is a significant risk that costs could escalate as the project develops.

The report also raises concerns over governance arrangements, particularly the involvement of HS2 Ltd in developing plans for parts of Northern Powerhouse Rail. Given HS2's well-publicised difficulties with cost control and programme management, the committee believes stronger oversight and accountability will be essential if similar problems are to be avoided.

Alongside financial and governance issues, the PAC highlights wider delivery challenges. Planning requirements, environmental mitigation, biodiversity commitments and coordination between local authorities and combined mayoral authorities all have the potential to increase costs and add complexity if not managed effectively from the outset.

Despite its criticisms, the committee remains supportive of the overall aims of Northern Powerhouse Rail. Improved east-west rail connections between cities including Liverpool, Manchester, Bradford, Leeds, Sheffield, Hull and Newcastle are widely regarded as vital for boosting regional productivity, supporting economic growth and improving connectivity across the North of England.

The Department for Transport has rejected suggestions that Northern Powerhouse Rail will follow the same path as HS2. It says lessons have already been learnt through the implementation of recommendations from the James Stewart Review and that a phased development approach is now being taken, with detailed engineering work progressing alongside regional partners.

Industry organisations have also continued to back the project, arguing that improved rail infrastructure will play a key role in supporting long-term economic growth. However, many agree that robust governance, realistic budgeting and close collaboration between central government and regional authorities will be essential to ensure the scheme delivers on its ambitions.

The Public Accounts Committee concludes that political commitment alone will not guarantee success. Without a clearly defined scope, stronger financial discipline and effective project management, Northern Powerhouse Rail risks repeating many of the mistakes that have overshadowed HS2. As development continues, the government faces increasing pressure to demonstrate that the UK's next major rail investment can be delivered on time, within budget and with greater confidence for taxpayers.
