The 75 miles from Saltash to Penzance contains the greatest number of viaducts per mile on any British Railway and such exaggerated curvature that there is only one dead straight mile of track throughout. Once again, virtually the whole route is shown including the many single line sections. There are dozens of aerial views taken from a helicopter on both of the above productions. Features include the Atmospheric Railway pump house at Starcross, Dobwalls miniature railroad and the Bodmin Steam Railway.
