The Festiniog & Blaenau Railway (F&BR) was a narrow gauge railway built in 1868 to connect the town of Blaenau Ffestiniog in Wales with the slate quarries around Tanymanod and the village of Llan Ffestiniog, to the south. At Blaenau Ffestiniog it made a direct connection with the Festiniog Railway (FR) with which it was closely associated during its fifteen-year life. The railway was purchased by the Bala and Festiniog Railway in 1883 and converted to to extend the Bala Ffestiniog line, a branch of the GWR's line from Ruabon to Barmouth.
