Lyrics

 * Bertie: Thomas?
 * Percy: Thomas? Has anyone seen Thomas?
 * Toby: Thomas? (Thomas? Thomas?)
 * Gordon: He could have bashed into some buffers
 * Diesel: Or dropped down into a mine
 * Percy: Or rolled into the ocean 'cuz he passed the danger sign
 * Rosie: He could be stuck inside a tunnel with no steam to move at all
 * Edward: Or crashed into a stationmaster's house
 * Knapford Stationmaster: Right through a wall
 * Toby: He could've strayed into a woodland on a track that's overgrown
 * Paxton: Or found a secret tunnel to some island that's unknown
 * Sidney: That doesn't make any sense! How could there be an island around here that's unknown?
 * Paxton: What if it was always covered in mist?
 * Sidney: That sounds very mist-erious!
 * Marion: He could be caught up in a landslide
 * Bill: Or have fallen off a bridge
 * Ben: Or tried to climb a mountain
 * Timothy: And be stuck up on a ridge!
 * James: He could've been derailed when he was trying to win a race
 * Imprisoned in a Steelworks!
 * Percy: Or be lost in outer space!
 * Sir Topham Hatt: Fat Controller/Sir Topham Hatt to major Thomas... come in major Thomas
 * Stop messing around, you're causing confusion and delay!
 * James: He could've gone up to some other place that we don't even know!
 * Henry: He could be almost anywhere!
 * Sir Topham Hatt: Oh, where did Thomas go?
 * Percy: We don't know, sir!
 * Sir Topham Hatt: Well, keep looking!
 * All: He could be anywhere, any where's Thomas?
 * He could be anywhere, any where's Thomas?
 * He could be anywhere, anywhere into the world
 * Emily: Sir, sir, sir! I found out what happened to Thomas!
 * Sir Topham Hatt: Alright, Emily. Calm down, and tell me slowly.
 * Emily: Thomas went down to the Docks, sir. And... and Carly loaded him onto a ship!
 * Sir Topham Hatt: She did what? But... that means... he could be anywhere in the world!
 * He could be checking out the pyramids while floating down the Nile
 * Or in the outback of Australia with a crocodile
 * He could be in Paris, sitting by the Eiffel Tower
 * Or chilling in Antarctica...
 * Dowager Hatt: He wouldn't last an hour!
 * Sir Topham Hatt: He could be in the Himalayas taking in the mountain air
 * Or acting like a tourist in the heart of Time's Square!
 * Percy: Are there tracks there?
 * James: Of course! The subway goes right through it.
 * Percy: You mean he's gone underground?
 * Thomas: Hello! Hello?
 * Sir Topham Hatt: He could be in Rio de Janeiro as the carnvial goes by
 * Or out on Easter Islands saying "hi" to a moai
 * Thomas: Hi!
 * Moai Head: Hi
 * Sir Topham Hatt: He could be on an African safari racing a zebra
 * Or in Venice on a gondola!
 * Dowager Hatt: Don't be preposterous! He's a tank engine. He can't fit in a gondola!
 * Sir Topham Hatt: Well he could if it was a rather large gondola
 * He could be wrestling a sumo in a match in Tokyo
 * He could be almost anywhere
 * Oh, where did Thomas go?
 * Henry: We still don't know, sir!
 * Sir Topham Hatt: Well, we have to find him. He's my number one engine.
 * All: He could be anywhere, any where's Thomas?
 * He could be anywhere, any where's Thomas?
 * He could be anywhere, anywhere into the world
 * Sir Topham Hatt: Oh Thomas, where could you be?

 * In the overhead shot of Knapford Yards, Norman, Stanley and Stafford's eyes are not animated and appear closed.
 * Ben's body has been raised noticeably higher compared to his chassis.
 * Although voiced by Ramsus Hardiker, Bill's voice sounds much deeper than it does in later instances.
