This is a list of heritage railways in Australia, some of which can also be considered tourist railways. For convenience, heritage tramways have also been included. Most are members of Association of Tourist & Heritage Rail Australia (ATHRA).[1] In addition to active operations, abandoned and putative operations are also included, but static museum sites and rolling stock operators without a 'dedicated' line do not fall within Wikipedia's definition of heritage railways. Miniature railways with gauges of less than 380mm (15 in) are excluded. Lines named in red are lacking a detailed Wikipedia entry.
The world's second preserved railway, and the first outside the United Kingdom, was Australia's Puffing Billy Railway. This railway operates on 24 kilometres (15 mi) of track, with much of its original rolling stock built as early as 1898.
