Thomas and the Magic Railroad2000

Mr. C [narrating]:
And by the way, I think that you're going to help me and Thomas somewhere in this story.

Thomas:
Ooh. If Diesel (10) has unfinished business, there's sure to be trouble right around the corner.

James the Red Engine:
[a fly buzzes in front of him] Sandal, fly! Boot, fly! Shoo, fly! That's it! [Thomas shows up] Better still? Buzz off!

Thomas:
[hits the buffers too hard] Botheration!

James:
You weren't concentrating, Thomas. Lucky for you that the buffers were there.

Thomas:
That's what buffers are for - to stop engines from crashing. What are you doing in the sheds, James?

James:
I'm feeling a little blue, which isn't so hot when you're red. I was naughty, and Sir Topham Hatt told me to think about all the ways I can be really useful, then I could come out again.

Thomas:
He's just trying to make this a better railways for steam engines.

James:
[notices Diesel 10] Uh...

Thomas:
Sir Topham Hatt says...

James:
Thomas...?

Thomas:
...The harder we work, the less he'll need Diesels to help.

Diesel 10:
Help you? [chortles]

Thomas:
Oh!

Diesel 10:
You always need help. Because steam engines are cowardly, cranky, worn out hunks of metals who couldn't hurt a fly!

James:
[scoffs] No, we're not!

Diesel 10:
Yes, you are!

James:
Aren't!

Diesel 10:
Are! Now, I've come back to find the lost steam engine.

James:
What?

Diesel 10:
I'm gonna destroy her and dominate you, and then you'll be nothing but useless scrap! [to his claw] Right, Pinchy?

James:
Big bully! [Diesel 10 laughs and leaves] STINKER!

Thomas:
We're really useful engines. You won't dominate us, and you won't destroy her. We won't let you, neither will Mr. Conductor. I'm off to fetch him now!

James:
What lost engine?
