Gordon, Edward and others in “Wrong Road”

It's not fair.

What isn't fair?

Letting branch line diesels pull main line trains.

Never mind, Gordon. I'm sure BoCo will let you pull his trucks sometimes.

Gordon spluttered.

I won't pull BoCo's dirty trucks! I won't run on branch lines!

Why not? It would be a nice change.

The Fat Controller would never approve. Branch lines are vulgar!
