The Puffing Billy Railway is a 2 ft 6 in (762 mm) narrow gauge heritage railway in the Dandenong Ranges near Melbourne, Australia. The primary starting point, operations and administration centre, main refreshment room (also selling souvenirs) and ticket purchasing are located at Belgrave station. Journeys may also be commenced at out-stations of which some have limited facilities for the purchase of tickets, refreshments and souvenirs. Tickets usually may also be purchased from the conductor aboard the train.
The railway was originally one of five narrow gauge lines of the Victorian Railways opened around the beginning of the 20th century. It runs through the southern foothills of the Dandenong Ranges to Gembrook. Being close to the city of Melbourne and with a post-preservation history spanning over 50 years, the line is one of the most popular steam heritage railways in the world, and attracts tourists from all over Australia and overseas.
The Puffing Billy Railway is kept in operation through the efforts of volunteers of the Puffing Billy Preservation Society, although intensive year-round operations have led to a few dozen paid employees to keep things going behind the scenes.
The railway aims to preserve and restore the line as near as possible to how it was in the first three decades of its existence, but with particular emphasis on the early 1920s.
