High Speed 2: the business case, costs and spending
This paper shows that while HS2 will deliver significant capacity and connectivity improvements, there are alternatives available that could deal with the capacity constraints on the West Coast Main Line at a lower cost. This paper also shows that there is still uncertainty around the costs of HS2. The estimates at the time of the 2015 Spending Review put the cost at around £65 billion (in 2015 prices). The ambitions of HS2 Ltd are to reduce the costs of the infrastructure for Phase 2b by around 40% from the 2015 Spending Review estimate.
