Faisal Islam: Why a Full HS2 Line Could Still Be Built Despite the Latest Fiasco

Why It Matters

A truncated HS2 threatens to undermine the strategic goal of rebalancing the UK economy, while still demanding a massive fiscal commitment. The outcome will shape Britain’s high‑speed rail future and its ability to compete with faster, cheaper projects abroad.

Key Takeaways

• HS2 cancellation costs match completion costs, about £60bn ($75bn).
• Only West London–Birmingham segment likely to finish by late 2030s.
• Reduced line will force slower 110 mph services on WCML, below Pendolino speeds.
• Northern Powerhouse Rail uses HS2 rights to extend to Manchester, cutting costs.

Pulse Analysis

The HS2 saga illustrates how political ambition can outpace realistic planning. Originally conceived as a Y‑shaped high‑speed corridor, the project promised to knit together London, the Midlands and the North, spurring agglomeration benefits and a more balanced economy. Yet escalating budgets, contractual missteps and public backlash have stripped away the Manchester and Leeds branches, leaving a solitary London‑Birmingham spine. With an estimated £60 bn (£75 bn) price tag for either cancellation or completion, the government faces a stark choice: write off sunk costs or press on with a scaled‑down line that still demands a near‑century‑scale investment.

Technical challenges now dominate the conversation. The unfinished HS2 segment will ultimately merge onto the West Coast Main Line, a 19th‑century artery already operating at capacity. HS2 rolling stock, designed for straight, high‑speed tracks, cannot negotiate the WCML’s tighter curves, limiting speeds to 110 mph—slower than the 125 mph Avanti Pendolinos that already ply the route. This mismatch threatens to exacerbate congestion, erode the promised time savings and diminish the line’s commercial viability, raising doubts about the value of the remaining investment.

Looking ahead, policymakers see an opportunity to salvage value through Northern Powerhouse Rail, which could repurpose HS2’s legal framework to extend a cheaper western leg to Manchester Airport. Lower land costs and fewer tunnelling requirements could reduce per‑mile expenses, aligning the project more closely with international examples where high‑speed rail is delivered faster and cheaper. Whether the UK can translate these lessons into a pragmatic, cost‑effective network will determine if HS2 becomes a cautionary tale or a stepping stone toward a modernized rail future.
