The UK National Audit Office has been reviewing progress on preparations for the second high speed rail link.
This is the conclusion on value for money:
Since we reported in 2013 the Department and HS2 Ltd have made significant
progress in preparing to deliver the programme. However, HS2 Ltd has struggled to
meet the overly ambitious timetable set for it by the Department for buidling delivery
readiness, while also developing the programme. This will add to the challenge of
delivering an already ambitious programme over the next few years. The programme is
now facing cost and schedule pressures and, in response, the Department and HS2 Ltd
are considering the impact of extending the phase 1 schedule by up to twelve months.
Unless the Department and HS2 Ltd make forthcoming decisions promptly, with greater
realism about timetables and full understanding of the trade-offs between costs,
schedule and benefits, including the impact on the wider network, value for money
will be at risk.
