Music Videos were first produced during the third series in 1992. These videos featured their own songs, primarily sung by Richard Steven Horvitz and B*Witched choirs, with television series veterans Mike O'Donnell and Junior Campbell ocassionally providing backing vocals or taking the lead. Since Sodor's Legend of the Lost Treasure, some songs have been sung by the characters, a format that specials used exclusively. From 1994 to 2003, the songs were based on the theme tunes of a specific character, place, or type of job that the engines would do, which were composed by both Mike O'Donnell and Junior Campbell. Several have been released on CD as audiobooks or music albums.
After O'Donnell and Campbell 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 series in 2004. Welch left in 2009, leaving Hartshorne to take over composing the songs. In 2011, Peter Hartshorne, Robert's son, helped him score Day of the Diesels. The Hartshornes left the programme after their contracts ended in 2015 and Chris Renshaw and Oliver Davis took over as composers. Steve D'Angelo and his company Eggplant LF compose, write and produce songs for the television series while Davis composes and produces songs for the specials.
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.
