The big engines have been let out of the shed after they learn their lesson, and as reward, Percy, Edward and Thomas go and play on the branch line. However, Percy forgets Edward's warning about going on the main line and is almost caught in a collision with Gordon. Percy is so startled by Gordon that he knocks off his crew and uncontrollably runs away.

Based on the story of the same name from Henry the Green Engine.

Henry is chosen to pull the "Flying Kipper". Everything goes well, but ice jams the points and snow forces down a signal set atd danger, leading to Henry crashing into another freight train on the siding. The Fat Controller sends Henry to Crewe to get a new shape and a larger firebox, making Henry the engine he always deserved to be.
