The decision, outlined to Graham in a letter from Network Rail Chief Executive David Higgins, means that work on the Curve could receive financial support in the next funding period.
Graham commented: 'Reinstatement of the Halton Curve would provide a huge boost for local residents and businesses in Frodsham, Helsby and Runcorn, with extra services and a new connection to Liverpool Airport and Liverpool.
'I hope that the feasibility study shows the real and significant economic benefits that these additional links would bring.'
