Ffestiniog Railway Fairlie 12 David Lloyd George leaves Blaenau Ffestiniog with the 11:45 train to Porthmadog on 4 June 2005. It had just about stopped raining, but the clouds are still enveloping the mountains in the background. Note the standard gauge line to Llandudno Junction in the foreground. David Lloyd George was built at the railway's Boston Lodge works in 1992, and is the most powerful double Fairlie locomotive in the world.
