The Lake Margaret Tram was located on the western side of Mount Sedgwick in the West Coast Range on the West Coast of Tasmania in service for the Mount Lyell Mining and Railway Company to the Lake Margaret community.
As access onto the plateau was steep, a self-acting 2 ft (610 mm) narrow gauge dual haulage was built.
[1] Following the decision to build the Lake Margaret Power Station, the Howard's Plains Tram was extended from its then terminus at the 4¼ mile peg.
[1] Following the completion of the power station on 28 November 1914, the tram continued to provide firewood as well as a freight and passenger service for employees and their families living at the isolated settlement.
