Puffing Billy's line began operation in 1900. It carried large quantities of timber, potatoes, as well as weekend visitors looking for a day trip. Although electric trains arrived, the train continued on. The only thing that could stop it were two landslides. In 1954 the train was officially farewelled.
The Trestle bridge, just out of Belgrave is one of the largest wooden railway bridges. It is one of the most easily recognised parts of the track. A viewing area is located near by for observors to watch the train cross over. Several smaller trestle bridges were recreated in between Lakeside and Gembrook, though none as impressive as the Trestle Bridge.
