The Train Shed operated a 7.25" gauge Miniature Railway with a Thomas theme from 1996 until 2014 on the western outskirts of Sydney. The railway was built over the 16 years of operation, growing to around 1km of track, with a turntable, traverser, storage sheds, tunnel, bridge, and three stations. The railway operated at its peak with seven four-car enclosed trains in continuous operation, for 150 days per year. A portable track was also regularly taken to Exhibitions and Fetes, with Thomas and a second character running rides for the days.
