As the 20th Anniversary of the Ffestiniog Railway reopening to Blaenau Ffestiniog approaches, here is the first in a series of 'photo specials' showing the construction of the spiral at Dduallt, the new line and tunnel between Dduallt and Tanygrisiau, and the work to restore line from Tanygrisiau to Blaenau Ffestiniog. These photographs were all taken by Chris Jones.
