Jack Jumps In is the seventh episode of the sixth season.


Thomas takes an eager front-loader named Jack to help the Pack clear ground for railway lines at the quarry. Jack looks for his work, and finally finds it, working with a small excavator called Alfie. Then, a dump truck called Max comes along and causes dust to fly over the machines. Jack tells Max to stop bullying. Max scowls and races away. Later, an excavator named Oliver is ordered to move a pile of rocks, but Jack foolishly tries to take some of them up a hill himself. As he approaches the top of the hill, he loses his balance and rolls down sideways. Jack is upset and Miss Jenny is disappointed, but Isobella, Alfie and Thomas comfort him, which makes him feel better.




  • This was the first episode directed by Steve Asquith.
  • This was the first episode not directed by David Mitton. However, it is unknown if he was involved in the episode's production.
  • The working title for this episode is "Jack Goes to Work" although it was given that title on the Thomas and the Jet Engine DVD.
  • Alec Baldwin's narration has only been broadcast on the Canadian television station TVO Kids.


  • Thomas leaves with the wellwagon after delivering Jack, but in the close-up of Jack, the wellwagon is still behind him.
  • Studio equipment can be seen in the top-right corner when the narrator says "Byron the bulldozer was shoving rock and rubble with his giant blade."
  • When the foreman introduces himself to Jack, he has a moustache, red hair and a hat. When he says "Oliver, move this rock!" he has a hard hat and no moustache.
  • When Jack introduces himself to Alfie, Alfie's front-left tyre is flat.
  • In some shots, a wire is visible under Alfie's hydraulic arm.
  • When Isobella yells "No!" when Jack goes up the hill, wires can be seen in her cab.
  • Before Jack barrel-rolls down the slope, his two left wheels change colour.
  • When Miss Jenny says "We'll see if you can do better tomorrow," Oliver is smiling even though Jack is in trouble.
  • When Max spins around, the turntable that makes him spin is visible.


  • Jack: I'm Jack!
  • Isobella: Mind my paint!
  • Max: Can't you take a joke?


  • Take Along (four-pack and movie car; both discontinued)
