Percy, James and others in “Percy and the Signal”

I say, you engines, I'm to take some trucks to Thomas' junction. The Fat Controller chose me especially. He must know I'm a really useful engine.

More likely, he wants you out of the way.

Gordon looked across to James. They were making a plan.

James and I were just speaking about signals at the junction. We can't be too careful about signals, but then, I needn't say that to a really useful engine like you, Percy.

Percy felt flattered.

We had spoken of backing signals. They need extra special care, you know. Would you like me to explain?

No, thank you, James. I know all about signals.
