Based on the story "Resource and Sagacity" from Oliver the Western Engine.

Oliver is new to the island and all the engines complimenting his courage makes him conceited. He pays no attention to Duck's warning about being careful with the Troublesome Trucks when he is asked to handle them for his next job and gets in a nasty accident in the turntable well. He pays dearly for it.

Based on the magazine stories "In a Muddle" and "Heroes."

Bill and Ben mistrust a group of trucks into telling them how to set up things at the harbour station causing confusion and delay. However, they become heroes after saving the workers when a rock-slide suddenly strikes the clay works.
