The government has confirmed it is examining plans by a private company to reopen an old railway line closed 25 years ago.
Translink are planning the route through the Peak District
Translink UK wants to run trains on the Manchester to Sheffield Woodhead route, through the Peak District.
Translink has claimed a specialised service of shuttle trains could take 90% of heavy trucks off the A628 road through the national park.
It wants to spend £159m relaying 35 miles (56km) of track.
The service would have special roll-on roll-off terminals at each end.
Translink believes it will be quicker than driving and will reduce pollution and congestion in the National Park.
But sceptics contend the idea will not work because lorry firms will not be willing to pay for the shuttles.
The Department for Transport said it had received a formal proposal from Translink and was looking at the idea.
