Charlie the Choo-Choo [pic]

From Stephen King’s The Dark Tower III: The Waste Lands

Engineer Bob sat in the cab, pulling the whistle-cord and looking as happy as a pig in shit. Jake supposed Engineer Bob’s smile was supposed to convey supreme happiness, but to him it looked like the grin of a lunatic. Charlie and Engineer Bob both looked like lunatics . . . and the more Jake looked at the kids, the more he thought that their expressions looked like grimaces of terror. Let us off this train, those faces seemed to say. Please, just let us off this train alive.
