This has been muted for years now and it won't happen,theres too much work required to re-instate the present line quality, let alone the bit thats missing
Network rail , believe it or not, have spent lots of money replacing worn track between Ponts Mill and Goonbarrow , with more to do soon,I cant see them closing it down to freight only and spending 5 times as much again on the track between Burngullow and St Dennis Jn.
I wonder if this story is attempt to scupper the plans to rail waste to the new incinerator (if it ever gets built). A passenger service over the line would surely prevent freight from operating any sort of reasonable service over the line again
