A new park on the Little Engines' railway is being built. The final thing to add before the opening is a statue of an elephant, hence the name: "Elephant Park".

Duncan is being impatient as usual and seeing as he is finished before the other engines, the Fat Controller orders him to take the elephant to the park. However, the foolish little engine realises too late that it's "Better safe than fast" when he leaves without waiting for the brakevan and is dragged down the line with the heavy load. Will he be able to stop in time?
