Music Videos first materialised during the third season in 1992. These music videos all featured their own songs, mainly sung by children. From 1994-2003, the songs were based on the themes tunes from a specific character, place, or type of job that the engines would do, which were both composed by television series veterans, Mike O'Donnell and Junior Campbell.

After Mike and Junior left the series after twenty years, Robert Hartshorne began composing the music for the series, while Ed Welch wrote the songs, both starting from the eighth season in 2004. When Ed Welch left in 2009, Robert Hartshorne was left to compose the songs on his own. However, in 2011, Peter Hartshorne, Robert's son, helped him score Day of the Diesels.

The music videos are known for using clips from the series along with deleted scenes which would not be seen in the episodes themselves. Some music videos have specially-shot footage, which would only happen if the song did not have the required clips from the archives.
