Have you been to the Canberra Miniature Railway in Symonston? It is a popular, family-friendly venue that is just a short drive south of the city centre. Kids (and parents!) will enjoy riding on the miniature train rides, at a cost of $3 per ride. Stay and enjoy food from the canteen and admire the variety of trains in the yard. The running day will be open between 10am - 2:30pm - see the Canberra Miniature Railway website for directions and parking.
