The Bush Mill Railway was a 15 in (381 mm) gauge miniature railway, situated 2 km (1.2 mi) from Port Arthur, Tasmania.
[1] The 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] A 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.
The railway also had five semi-open coaches and two coal wagons, these became part of the collection at the Cleethorpes Coast Light Railway and the coaches have now moved on to the Sherwood Forest Railway.
