- Narrator (UK): One day, Percy arrived at the quarry to collect some stone for his trucks. Snow and frost lay everywhere. There was not a sound to be heard. Percy ventured further. He found Mavis, the new diesel engine, resting in the shelter of some rocks.
- Percy: Cheer up, Mavis.
- Narrator (UK): Mavis was still remembering the trouble she had with trucks.
- Mavis: Manager says I don't listen to advice. He says I have no business jaunting down Toby's line. Toby's a fusspot!
- Percy: [angered] Toby has forgotten more about trucks than you will ever know. You must put the trucks where he wants them, then you'll be a useful engine. Now, if you'll excuse me, I have to take these stones to the harbor.
- Narrator (UK): [as Percy leaves with his stone trucks] Mavis liked Percy, but she still wouldn't listen to his advice.
- Mavis: [to herself] Why shouldn't I go on Toby's line?
- Mavis: [after rescuing Toby from the tightrope bridge] I'm sorry about the trucks. I can't think how you managed to stop them in time.
- Toby: Oh well. My driver told me about circus people who walked tightropes, but I just didn't fancy doing it myself.
