Northern Powerhouse Rail preparatory works
North of England (Liverpool, Manchester, Leeds, York), UK · 2026–ongoing (preparatory works and planning) · Approx. £3.5bn (Liverpool to Manchester via Warrington) and £4.2bn (Manchester to Leeds via Bradford) (indicative values)
The judgement call
Account-gated at launchThe NAO highlighted the need for better cross-government working and stronger ties to the government's economic strategy. - DfT has taken steps to set up the programme for success by identifying key lessons from other major rail programmes, such as HS2. - The importance of providing clarity over the programme's scope to avoid uncertainty and delays in delivering benefits like more frequent and faster rail services.
Key engineering challenges
Integrating new high-speed lines with existing, heavily constrained Victorian infrastructure across the Pennines. - Managing significant scope changes over a decade, which created uncertainty and delayed benefits. - Ensuring effective cross-government working at both national and local levels to align with economic growth plans.
