This song has the same chord progression as Go, Go Thomas.
When the song was aired on television, the song excludes the lyrics about the engines working together to rebuild the Dieselworks. It even repeated the chorus twice at the end.
As the order of the engines named during the German version of the song was changed, Diesel 10 is shown when "Norman" is sung and mirrorwise.
K.NET's Korean version of Day of the Diesels, it plays the instrumental version.
This song was never dubbed in Korean.
Sidney is the only diesel engine that is not named in the lyrics for unknown reasons.
Goofs
In the German version, Thomas is once incorrectly addressed by a German form of his name. In the German dub itself, his name is spoken like it is in English. During the rest of the song, the characters' usual naming is used.
