Willans Hill Model Railway is located in Wagga Wagga Botanic Gardens in the suburb of Turvey Park in Wagga Wagga, New South Wales, Australia.
The railway was established in 1982. It is operated by the Wagga Wagga Society of Model Engineers. It includes 2 kilometres of track, two stations, several buildings, bridges, tunnels and a number of locomotives owned by the club or individual members.
The railway is open to the public on the 1st and 3rd Sundays of each month. Each ride is A$2.00. Covered footwear is essential for rides. Opening times 10.30am to 4.30pm with a lunch break between 12.30pm and 1.30pm.
An annual Invitational Run happens on the 1st weekend of November. Miniature trains from all over Australia converge here for two days of train running. Traditionally, the Saturday is for club members only and the Sunday event is open to the public.
The first 24 hour run, called Railway for Life, was held 15-16 September 2007 in aid of the Cancer Council.
There are currently two routes in use. The main line which is a shorter route that runs within the boundaries of the botanical gardens itself and the museum line which takes the trains under Lord Baden Powell Drive over to the loop next to Museum of the Riverina car park. Current extension to the main line includes a spiral.
