Duck was sent to the works for a routine service. The workmen were giving him a full inspection to see if there are any old or worn parts and finish him off with a good clean. By the time they were finished, Duck felt like he was a brand new engine. Duck was excited to get back to work. He pulled goods and passenger trains up and down the mainline that by the end of the day he was not tired at all. Duck took Percy's mail train under the Fat Controller's approval but he was still not tired. So the next morning, Duck asked Henry if he can take the Flying Kipper for him, which Henry accepted. So Duck raced away to collect the fish train. Later that morning, the stationmaster was waiting for Duck to take a light goods train but he was nowhere in sight. But they saw, down in the siding, Duck was asleep. Even engines who feel brand new need their rest.
