Diesel mentions that he is the Fat Controller's first diesel engine, which is most likely intended to be a reference to Pop Goes the Diesel.
In the US version, when Duck, Stanley, Edward, and Norman sing "Please Sir, I beg you, I just have to know", they sing it one at a time, but in the UK version, they sing it at the same time.
This is the only song featured in The Great Race which does not have an alternate version of itself.
There are eleven animation and voice errors in the song, these being:
When Thomas enters Knapford, in the first shot he is already inside the station, but in the next shot he is seen entering the station again.
When the song first begins, Thomas' driver's elbow clips through his cab door.
Duck is not steaming as he goes through Knapford Station.
In the US dub, when Stanley and Norman first speak, their voices are swapped over.
As Gordon pulls into Knapford, Emily is leaving the station with a row of coaches. The second coach's body is missing, as only its chassis can be seen.
When Gordon sings the audio from the singing and the mouth animation don't sync.
Thomas goes over Henry's tunnel, despite the fact that there aren't any rails.
Rex's tender merges through his cab and his driver's head sticks through his boiler.
Towards the end of the song:
In the US dub, when Gordon, James and Diesel sing "Will you, won't you take us to the railway show," Emily's voice can be faintly heard, her voice can be heard again when Henry, Duck, Donald and Douglas sing "Will you won't you take us to the railway show." she can even be heard laughing when Thomas arrives at the yard to sing along.
In both dubs, Percy's UK voice can be heard when Henry, Duck, Donald and Douglas sing "Will you won't you take us to the railway show.", but he is nowhere to be seen in either scene.
In the UK dub, when Thomas comes in, James is seen laughing but his voice isn't heard. This could be because his voice was drowned out by Gordon and Diesel.
Stephen's wheels are moving slower than his side rods are.
Towards the end of the song, James' bufferbeam clips through Gordon's running board. In the same shot, they stop moving, but in the next shot, they stop moving again.
