This is from Network Rail's website. It inadvertently describes very eloquently the current situation on the Far North Line, the Highland Main Line and the Inverness to Aberdeen (A2I) route. There is an imminent need to provide extra capacity for passengers, and especially freight, on these lines too, so that modal shift can take place.
We're upgrading the railway between Manchester and Sheffield to provide more reliable and faster journeys for passengers.
The Hope Valley Railway Upgrade will remove several bottlenecks between Manchester and Sheffield to allow passenger trains to overtake slower freight trains along the line.
The main improvements include:
Once complete, this project will deliver real benefits for passengers in the North of England, with improved train reliability and an upgraded network to help meet future demands.
The work to upgrade the route is being undertaken on behalf of Network Rail by a joint venture of VolkerRail and Story Contracting Ltd - the VolkerRailStory Joint Venture (VRSJV).
