HS2 Completion Costs Rival Cancellation

Why this is here: The total cost of HS2, if completed from its current stage, is estimated to reach approximately £100 billion, making it the world’s most expensive railroad.

Mark Wild, HS2’s boss, estimates completing the project from its current point would cost about £60 billion, bringing the total to roughly £100 billion. The original HS2 plan envisioned a Y-shaped line from London to both Birmingham and then onward to Manchester and Leeds, intended to boost economic growth across the UK.

However, after the cancellation of the Leeds and Manchester legs, the Department for Transport determined the project’s strategic case—economic rebalancing—no longer held. Now, HS2 is set to deliver a line connecting west London to Birmingham, but not until the late 2030s.

Trains traveling on the existing West Coast Main Line after leaving HS2 will be limited to 110 mph, slower than current services. Completion of the line to Manchester, utilizing existing Northern Powerhouse Rail plans, may offer the greatest benefit for the lowest cost, though the UK still lags behind other nations in high-speed rail delivery.
