In Dolgellau, Rob meets a local harpist and hears the sounds that became intrinsically tied to the image of Wales.

Rob Bell seeks out the lost railway from Elgin to Portsoy, a line which served the fishing and whisky industries so vital to the local communities. The track bed to the 'Scottish Riviera' of Lossiemouth once saw sherry barrels aplenty and vast quantities of fish along its surprisingly straight route - the picturesque docks still betray the presence of steel track right up to the water's edge. Rob is helped in detecting the line by local ramblers, but he's quite unprepared for the sight that awaits him: the magnificent Spey Bridge. Salmon fills the river here and once ...

This is the story of a freight line, built to traverse the tricky landscape of the Lake District to transport minerals from the many Cumberland mines, but which later was embraced by tourists eager to explore the spectacular countryside.
