The Puffing Billy miniature railway runs between the towns of Belgrave and Emerald in the Dandenong Mountains of Victoria. Supported and operated by amateur railway enthusiasts, with the assistance of the Victorian Government Railways, the Puffing Billy has become famous throughout Australia. Takes a light-hearted look at the problems of operating the railway. An affectionate salute to the people who keep this little railway running and to locomotive enthusiasts everywhere.
