Oh, oh, oh!
And I'm Possum.
Possum, great job.
Everything looks great.
I think it's time for a break, though.
Let's have something to eat.
This one's good.
Oh, hello, everyone.
Look at Possum playing with those cardboard boxes.
I wonder what game he's playing.
What are you doing?
I've made a train but, Sally, I don't know how to make it go forward.
Can you push me?
Me push you?
Oh, I couldn't possibly do that.
Trains have to run on train tracks.
They have wheels that lock onto the tracks and then they have an engine that makes them go forward.
This looks great.
I really do like what you've done here.
It's like wagons on trains – you can put different things in them and then those trains can deliver those things to different places.
It's quite an important thing they do.
There are even passenger trains where people can sit in them and travel around.
Oh, that's great!
Possum, you could possibly go and see Skip and ask him how trains go forward.
Skip knows lots about trains.
I thought Skip just knew about boats.
Hmm, you'd be surprised.
Skip knows lots about lots of things.
I'll go ask him.
When you do get there, make sure you press the doorbell and the light flashes.
Wait for Skip to come to the door and then ask him if he's busy or not.
If he says he's not busy, then you can ask him all sorts of questions about trains, ok?
Aye aye, Sally.
Come in, come in.
Are you busy, Skip?
Oh, I'm always busy, but for you, no.
Well, I was home making a train out of cardboard boxes.
Oh, cardboard boxes are a wonderful thing!
I've made many a boat and even a spaceship out of cardboard boxes.
Oh, that's great!
Anyway, so I've made this cardboard box train and it won't go anywhere.
I asked Sally to push me.
She didn't want to.
Then I asked her how to make it go forward and she told me to come and ask you.
Oh, that's a good idea to come and ask me.
Well, how does a train go forward?
For a train to go forward, it needs an engine and the engine is what makes the train move forward but the engine needs something to power it.
Like on a boat.
Like on a boat?
How does that work?
You've been on a boat before, haven't you?
How did you know?
Well, Sally had asked me if she could borrow my hat and telescope and I bet you would have pretended to be captain, right, and put them on!
Was that naughty?
Don't say sorry for that.
It's a good feeling to be in charge.
So, you went sailing.
Now, what was it that made the boat move?
Oh, I remember this!
The boat has a sail and the wind pushed into the sail and we went forward.
Yes, the wind gives the power.
That's what makes the boat move.
Can you imagine if there was no wind? What would happen?
Oh, I remember once being stuck at sea for five days with no wind.
Oh, terrible. Sorry.
The wind pushes the boat forward.
Ah, I've got it.
So if the train doesn't move, the wind will push it?
No Possum that would never work.
There are different types of trains, Possum.
There are electric trains that run like these lightbulbs.
There are diesel trains that run like a lot of cars run and then there's my favourite type of train.
The steam train.
That's like when you boil water in a kettle.
The water boils and then steam comes out.
That's exactly what it is.
I've just thought…I have a steam engine out the back.
I know that Sally would love to see it too.
Why don't you go get her and I'll get the engine ready?
It's all ready.
Come on in.
This is a steam engine.
Oh, it looks great.
Oh, that's great!
So, I'll explain to you how it works.
This is a fuel cell, and I'm going to light the fuel cell and it will create fire but you must always be very, very careful around fire.
So, the fire goes inside where the boiler is.
Now, the boiler has a lot of water in it, which gets hot and then the steam is created.
Sally, this is like your kettle.
When the water boils and all the steam comes out.
That's exactly what this is.
That's right, Possum and it's like my iron.
There's water in my iron and the steam comes out of the little holes.
Yes, yes – that's exactly right!
So, in the boiler the water gets very hot and the steam creates pressure that comes up through that pipe and puts pressure on the piston, which makes the piston move.
Is the piston going to pop off?
That's a very good question, though.
Have a closer look.
What can you see?
The piston is attached to the wheel.
It pushes the wheel around.
So it's not going to pop off.
Oh, this is just like a train.
Choo, choo, choo, choo.
Choo, choo, choo, choo.
Choo, choo, choo, choo. Choo, choo,
Choo, choo, choo.
Now, let's get the engine started.
Remember, always be careful with fire.
Oh, it's hot!
Yes, it's hot, Possum.
So, our fire goes in here.
Oh, it's going!
It's spinning really, really fast.
Now, can you tell me what's going on in here?
What have you learnt?
Right, well, here we have steam, and steam is the power for the train, just like the wind was the power for the boat that pushes it forward.
Yes, that's right.
It's going faster and faster.
But…but it's not moving.
It's not going forward.
Oh, this would need to have wheels attached.
This doesn't have any wheels on it, Possum.
Yes, and it would also need train tracks to roll on.
The wheels go on the tracks and then the steam power pushes it forward.
This is great.
I wish I could learn more about trains.
How can we do that?
I have a friend that I once helped build a train carriage.
I might go and ask him.
Let me turn the engine off first.
Hang on – I'll be back.
Sally, this was so much fun.
I really enjoyed it.
Yes, we've learnt lots, haven't we?
Why don't we watch some children learning more about trains?
Yeah, let's watch.
Oh, that looked great!
They had a lot of fun.
Did you see all the children laughing?
Oh, I wish I could do that too!
Right, the three of us are going to have some fun as well.
I had a chat with my friend – the one that I helped build the train carriage.
He's agreed to allow us to come and visit.
Does that mean we're going to ride a real train?
Well, it could be an electric train.
Or it could even be a steam train, Possum.
Well, why don't we go and see?
This is Brett.
He's the train driver.
Yeah, let's go.
Let's get on.
Oh, it's great.
In you go.
Oh, look at the kangaroos!
Oh, Sally, this is so much fun!
Oh, look at all the beautiful trees!
Yeah, let's look!
Oh, look, it's an eagle!
Yeah, an eagle.
This is great!
Oh, it's rocking.
It's slowly rocking.
Was that fun?
Oh, that was so much fun.
Oh, yes, it was great.
Let's go over here.
OK, let's go.
That was good, yeah?
Oh, that was great.
Oh, thank you so much, Skip.
It's my pleasure, Possum.
Well, our time is up.
Thanks for watching.
See you next time.
Oh, yes, let's look.
It's great, isn't it?
