Rusty and the workmen have repaired the railway line while Skarloey was away being mended. He is concerned about Duncan, who ignores his warning about a broken section of track. With a tip from James, Duncan is off on his own and he is soon "rocking n' rolling" along the rails. Rusty grudgingly comes to the rescue.

Based on the story of the same name from Gallant Old Engine.
