The Bush Mill Railway was a 15 in (381 mm) gauge miniature railway, situated 2 km (1.2 mi) from Port Arthur, Tasmania. It opened on the 4th of April 1986.[1]

Route
editThe Bush Mill Railway climbed steeply through a series of loops and zig zags up a hillside, then across a spectacular Serpentine Bridge. A half-size replica of locomotive K1, the world's first Garratt locomotive built for the North East Dundas Tramway, was constructed to operate on the line in 1990.[2]
Settlement
editA replica settlement was established which featured a 19th-century sawmill and a number of items which were directly related to the logging tramways which once dotted much of Tasmania.[3]
It closed on 30 June 2004.
