The government has hailed progress towards creation of High Speed 2 despite a cautious review of the scheme.
A report by the Major Projects Authority gave HS2 an ‘amber/red’ rating in the report due to the extent of work left to do on the £43bn project.
But it said work towards the £43bn rapid link between London and the North had gone well in the last 12 months.
“Significant progress has been made in the last year on HS2, for example in depositing the High Speed Rail Bill in Parliament and securing a successful second reading in the Commons,” said the report.
“The amber/red delivery confidence assessment on HS2, like other projects with a similar assessment, indicates that the focused attention that is being applied to addressing the remaining issues must continue.”
The Department for Transport insisted it remained on track to start work on HS2 in 2017.
A spokesman said: “HS2 is a vital part of the government’s long term economic plan and we are determined to ensure Britain will benefit from the jobs, skills and extra capacity it will provide.”
HS1 chairman Rob Holden this month told NCE he thought the government had failed to secure public backing for High Speed 2 (HS2). Holden urged it to be reconsidered as a non-high speed line to secure its future.
