A Puffing Billy maintanence worker pulls the coupler of steam locomotive 12A before being assigned to a passenger train at Belgrave station near Melbourne, October 20, 2014. While the discovery of steam power 200 years ago powered the Industrial Revolution, the world long ago shunted most steam trains onto the sidings of history. But in one small corner of rural Australia, the sights, sounds and smells of the Industrial Revolution remain very much alive. In the picturesque Dandenong Ranges on the eastern outskirts of Melbourne, Puffing Billy is Australia's last steam engine railway. REUTERS/Jason Reed (AUSTRALIA - Tags: SOCIETY TRANSPORT)
