Music Videos were first produced during the third series in 1992. These videos featured their own songs, primarily sung by local British children's choirs, with television series veterans Mike O'Donnell and Junior Campbell occasionally providing backing vocals or taking the lead. This lasted until the tail-end of the model series, and the songs have since been sung by professional singers. 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. At the end of all six episodes of "Mr. Conductor's Thomas Tales", "Thomas' Anthem" would play during the end credits instead of "Shining Time Station Theme Song". This was a short lived spin off series of "Shining Time Station" and aired on October 6, 1996 and ended on November 11, 1996. The series ran for six episodes and starred the late George Carlin as Mr. Conductor.
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 and would join him as a co-composer thereafter. Peter composed the 2015 film The Adventure Begins by himself, primarily basing the score off of O’Donnell and Campbell's music from the early series and recomposing two of their songs. 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 Great Race and Journey Beyond Sodor. Kevin Roberge, Carl Taylor and Noah Berg also wrote and composed songs from the twenty-first to the twenty-third series.
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.
