A racing car called Ace inspires Thomas the Tank Engine to become the first engine to travel the world, so Thomas sets off on an adventure which takes him to five continents, across deserts, through jungles and over dangerous mountains. On his journey Thomas meets Nia, an engine who teaches him that everyone needs a little help from their friends.

Bonus Features




  • When Ace jumps over the fence near Flying Scotsman, his front bumper clips through the rails as he lands. When he lands, his wheels stop moving.
  • When Thomas rerails the tankers, his side rod does not move, resulting in both it and his wheels being out of place.
  • A workman uncouples Thomas from the tankers when they're rerailed, but in the next scene, he is still coupled to them.
  • When at Knapford Station, the fish trucks are shown to have no faces, but at Vicarstown Station they have gained faces.
  • "Where in the World is Thomas" has several animation errors:
    • When Percy enters the yard a loading bay can be seen beside him but in the next shot it's gone.
    • Ben's body is raised noticeably higher.
  • After Nia says "I didn't mean to hurt your feelings," Thomas' train disappears before the scene changes.
    • Thomas' very long train in this scene has a brake van at the end of the train, but for rest of the time it is on screen it is absent.
  • The African crane tells Sir Topham Hatt that he loaded Thomas onto the ship to Brazil, when earlier in the special, the faceless grey crane near him was shown to actually be the one loading the engines.
  • Ace clips through a bush when he is racing in the Amazon.
  • When Yong Bao saves Thomas and Nia, the chain between the latter two clips through his snowplough.
  • In the UK dub, James' voice actor Rob Rackstraw gives him an American accent when he says, "Welcome to Sodor!".
