The Orange Society of Model Engineering will host its public running of miniature trains on Saturday, with young and old called aboard for a ride.

Society member Phil Pedley said it would have to pour rain or bucket five feet of snow for them to call it off.

"We normally run rain, hail or shine," he said.

Train lovers are invited to take a trip around the tracks at Matthews Park from 1pm for just $2.

Mr Pedley said they usually pack up at about 4pm, but the train rides finish when the last ticket has been punched.

Mullion Creek Public School will set up a barbecue to keep the crowds fed, with drinks, cakes and lollies for sale alongside the sausages.

"There's always plenty to see and plenty to do and since it's a public park people can do as they please," he said.

Train enthusiasts are asked to wear close toed shoes if they are going to hop aboard.

In the event of five feet of snow updates will be posted to the Orange Society of Model Engineering Facebook page.
