A train load of wild and wacky animals gets so noisy that the engineer has to shout to get them to quiet down. The little black train picks up yaks, acrobats, a troupe of ducks, and stomping elephants as passengers. But when two mice that are in to fireworks climb aboard, the engineer threatens to stop the whole train. “ ‘Keep it down!’ yells Driver Zach. ‘You’re giving me a headache attack!’ “ Everyone quickly hushes up, and soon, “the only sound you hear, in fact,/is the sound of the wheels on the railroad track. Clickety clack, clickety clack.” The words bounce along to the rhythm of a train on its way, and the swell of the sound effects makes this a joy to read aloud. Spengler’s robust illustrations capture an antic cast of passengers, conveying the action as much through composition as color. (Picture book. 4-8)
