The Rt Hon Margaret Hodge MP, Chair of the Public Committee of Accounts has told ITV Meridian that the Government should think 'long and hard' before justifying any investment in another high speed rail link in the South.
Her comments follow a report for the public accounts committee which claims that the new HS1 Channel tunnel rail link through Kent will cost the nation billions because passenger numbers were grossly overestimated.
Whilst HS1 provides an efficient service, it's left taxpayers with more than four billion pounds of debt, the report says.
It wants HS2 - a high speed rail route planned for Oxfordshire and Buckinghamshire - to be reviewed so it doesn't happen again.
