Imagine Jurassic Park with machines. The steam museum is laid out over 6 hectares of parkland so you can mix and mingle with a giant earth mover one moment then bump into a steam tank the next. The Centre is the headquarters of the Melbourne Steam Traction Engine Club (Yes, there is such a thing.)
Don't expect a lot of customer service. You're left to wander around on your own, but if you have any questions I'm sure the people you see tinkering around will know their stuff.
Besides the open fields, you can explore various workshops and see the engines at work. Different workshops house different engines such as jet engines, traction engines, ploughing engines and more. You can see them in action every fourth Sunday of the month when a selection of steam engines are fired up for show.
Mini train ride Throw in a train ride (about 1km around the premises) and you get a day the little one will be talking about for days to come. What I like best about the centre is that it is run by people who obviously love what they do. That alone makes the place pretty special, even if you don't have a clue what a Fowler 6nhp A4 is.
