Galloping Sausage is the sixth episode of Season 2, and the eighteenth episode overall.
Back three episodes ago, Sir Charles Topham Hatt spoke to Diesel about teamwork and his old tricks. If this was imminent, he could be sent back to British Railways and was the last thing the Class 08 locomotive had in mind. However, the locomotive needed to be adjusted and had been given more time to think about it within a few hours time to resolve his tricks and work with the steam locomotives. With Diesel's presence on the railway, Duck and Thomas talk about the fallout within Diesel before Gordon gets into the conversation. Gordon's special train is ready for Christmas Eve's night time experience. The express train's guard speaks to Gordon's fireman, but Gordon's driver accidentally pulls a lever and bangs his head on the platform after falling over. This means that the express is to run alone into the darkness.
After a good journey, the A0 Pacific finds out that his driver is not there, and is on a runaway from hell. All trains are stopped and even James has a shock for his life when Gordon passes him. Diesel explains to the GWR tank locomotive that if he can stop the A0 Pacific by himself, this means that Duck's driver can get into his cab and stop him. The Class 08 and A0 Pacific locomotives collide together and stop the runaway at a bridge. Duck comes soon after and Diesel speaks to the two engines about one of his brothers being cut up for scrap and killed in action. After Diesel's lies about working with the steam engines since 1957, both he and Gordon leave for Elsbridge where an inspector is waiting for them to investigate what happened at Knapford station and who did it.
