If you want a map to follow the route for yourself, there are none better than on Where's The Path. The OpenRailwayMap now contains many of the lcoal lines, disused or otherwise.
Click on the individual photos for further details, and to find other photos in the same 1km grid square. The photos are Creative Commons Licensed with full details on each Geograph page. There is some stunning photography here - a beautiful record of an old railway line which ran through a deserted and most beautiful landscape. Many thanks to the photographers. I hope you have as much enjoyment looking at it as I had in selecting the photos and putting it together.
