The big engines believe Edward has used up all of his steam and should be retired. Percy is concerned and tells the Fat Controller about it. Edward is sent to run a loop line with Stepney, while Duck has to deal with Edward's Troublesome Trucks. They become too much for him and he slowly stalls himself and Gordon. Only Edward can rescue them now.

Mending Rheneas and Skarloey's line takes up too much of Rusty's time, so the Fat Controller closes the line down and sends everyone to the quarry. The quarry will be blasting for two weeks though, so Rusty decides to use that time to repair Rheneas and Skarloey's line. However, they cannot do it on their own and need Elizabeth's help to get the job done.
