The Melba Line is a 1,067 mm narrow-gauge railway on the West Coast of Tasmania. The line was originally constructed as a private railway line named the Emu Bay Railway and was one of the longest-lasting and most successful private railway companies in Australia. While at present the line travels from Burnie to Melba Flats, it previously ran through to Zeehan carrying minerals and passengers as an essential service for the West Coast community.

The Emu Bay Railway was a Tasmania, Australian railway company. The railway was significant during full operation, in that it linked the Tasmanian Government Railways system at Burnie with that at Zeehan that further linked to the Mount Lyell railway allowing connection through to Queenstown.
