The Parliamentary Under Secretary of State for Transport, Stephen Hammond MP, says HS2 will be a huge boost for the Midlands.
The Conservative MP is at the first station to open in Birmingham, Curzon Street Station, to promote the rail line.
An influential group of MPs says the DfT has failed to present 'a convincing strategic case' for HS2.
Campaigners say they hope to put plans for HS2 through the Midlands back to square one as they prepare to go to the High Court tomorrow.
Campaigners from HS2 Action Alliance are heading to London tomorrow to take on the Government at the Court of Appeal.
