“Oh, no!” ―Thomas seeing the new car run away, Arthur's horror at upsetting the fish, Rosie getting splattered with mud, and Thomas again when the car crashed into a haystack Thomas and the Runaway Car is the seventeenth episode of the eleventh series. Thomas has been given the important job of taking the Fat Controller's new car to the Sodor Show. Gordon has been given the job of taking the bandstand to the show and challenges Thomas to a race. Gordon manages to get a head start and Thomas in a rush tells Rocky to hurry up with loading the car onto the flatbed, but Rocky tells Thomas to wait because he needs to be careful. The car is finally placed on the flatbed, but Thomas starts so quickly he does not wait for the Dock manager to couple him up to the flatbed. Rocky and the workmen try to tell Thomas, but he has already gone, determined to beat Gordon. When Thomas puffs to the top of Gordon's Hill, the flatbed rolls away from him and he chases after it. While Percy is waiting at a red signal, Arthur is pulling into a siding with heavy trucks of fish. Percy sees the runaway car coming and warns Arthur, who ends up backing up much too fast, biffing the buffers with fish flying in the air and splattering all over him. Up ahead, mud is all over the track and Rosie has just left the washdown. The runaway car runs past her, which causes mud to splatter all over her, making her cross at the predicament. The flatbed then races past Gordon and goes into a siding crashing into some buffers with the car then flying off and running into a haystack. When Thomas catches up, he sees what happened and Gordon, feeling triumphant, chuffs to the show. Thomas realises that he lost the race and the Fat Controller's car will never get to the show on time. He sets off to the Docks to get Rocky, but he stops knowing that he is not strong enough to pull Rocky on his own. When Gordon comes back after delivering the bandstand and winning the race, Thomas begs him to fetch Rocky. Gordon, taking pity on Thomas, is more than happy to help his friend as well as show off his strength. He goes to the Docks, fetches Rocky and brings him over to the hay field. After getting the car back on the flatbed, Thomas thanks Gordon by giving him the car to deliver and they arrive at the show together.
