The non-chorus verses have a very similar tune to the nursery rhyme "Jack be nimble" sped up.
It was listed as "On a Journey" when released on the US Nick Jr. website.
The Nick Jr. website later released a version of this song with additional sound effects and extra dialogue of Thomas laughing with Joseph May voicing him.
When aired on Nick Jr. between Unscheduled Stops and Springtime for Diesel, the first few seconds were missing due to a commercial break, along with commercials interrupting the song.
The last line of the official sing-along says "On a journey today", but Mike Ferfolia can be heard singing "We're on a journey today".
