Fairlies Patent double ended steam train, David Lloyd George. At Dduallt station on 12/02/2005, on route to Blaenau Ffestiniog. The deviation spiral at Dduallt is apparently the only peice of track of its kind in the UK. It's used to raise the track 35 feet so that it may pass behind the Ffestiniog Power Station. It was constructed in 1965. Photo by David Hall (4d@dink-a-tron.com)
