It is the longest running model railway exhibition in Australia and is the largest in New South Wales. The layouts on display cover all scales and prototypes, and come from all over Australia. It is the diversity and quality of the entrants that make the Sydney Model Railway Exhibition one of a kind.
Over the three days many thousands of people of all ages and interests attend. They see not just layouts but commercial stands and demonstration clinics. Also exhibiting are many kindred organisations including the Sydney Tramway Museum, Railway Transport Museum and the Australian Railway Historical Society. Thomas the Tank Engine rides are available.
