The NSW Rail Museum is the main museum division of Transport Heritage NSW. It was previously known as New South Wales Rail Transport Museum and Trainworks. The NSW Rail Museum houses Australia s largest collection of rail exhibits and undertakes regular rail heritage experiences across Sydney and NSW.

In 2013, Transport Heritage NSW was established by the Government of New South Wales to manage the State’s rail heritage collection and provide support to the broader transport heritage sector in NSW following an independent review. It operates the NSW Rail Museum and Valley Heights Rail Museum, as well as mainline steam trips and a number of events around New South Wales, Australia.
