The government is being urged not to cancel HS2 by the MP for Crewe and Nantwich.
If it is approved, phase two of the high-speed rail project will connect Birmingham with Leeds and Manchester, via Crewe.
Today, the Transport Secretary Grant Shapps has said a decision on its future will be made next month.
BBC Radio Stoke understands Dr Keiran Mullan is behind a letter from 40 MPs pushing for HS2 to go ahead, despite the overall project's expected £106bn price tag.
The congestion on the West Coast Main Line means that journeys are jam-packed, if there's a problem on one part of the railway it causes knock on effects locally and so I know residents want to see that investment locally in a new railway line to free up capacity."
