History
In 1988, producer Britt Allcroft began work on launching the Thomas franchise in the United States. Striking a deal with PBS, she co-created  with Rick Siggelkow, with the show acting as a vessel to introduce Thomas to American audiences. The series would be a half-hour program revolving around one or two episodes of Thomas and exploring the lessons and morals within the stories. Ringo Starr played Mr. Conductor, an eighteen-inch-tall man who told the stories of Thomas to the children who visited the station.

In a bid to fit the ideals of the American public, numerous changes took place to the episodes themselves. Several titles were changed; many technical terms were adapted to suit the American audiences' familiarity, and the title of 'Fat Controller' was politically corrected to 'Sir Topham Hatt' so as not to offend. The original British narration for the series was used, albeit slightly altered throughout with Ringo re-recording some parts to adapt the story with necessary changes, recommended by Allcroft's American television advisors, including child psychologist Dr. Ron Slaby.

After Ringo left Thomas and Shining Time to pursue his musical career, comedian George Carlin was brought in the replace him as Mr. Conductor in Shining Time Station and narrated the American dub (while Michael Angelis was brought in for the UK narration). Carlin also re-narrated Seasons 1 and 2 (11 of which Ringo had not re-narrated for US audiences). Following Shining Time Station ' s third season in 1992, the preference was to produce specials of that series instead. As a result, Thomas' fourth season was the first one to be released straight to video, which is how much of its future seasons would be released in the US.

Following Carlin's departure from the series after the fourth season, actor Alec Baldwin would be brought in to narrate the American version of the fifth season, and would later play Mr. Conductor in Thomas & the Magic Railroad. Baldwin would briefly return to narrate the sixth season in 2002, before moving on for his acting career. In 2004, British narrator Michael Angelis would very briefly re-narrate 6 episodes from the 7th and 6th series for the VHS and DVD release New Friends for Thomas & Other Adventures.

With the acquisition of the Thomas & Friends franchise by HiT Entertainment, the series was now redubbed for American audiences terrestrially in the United Kingdom. American-born actor Michael Brandon was brought in as the new narrator for American audiences, narrating seasons 7 through 16, as well as renarrating six episodes from season 6. Pierce Brosnan briefly served as guest narrator for the special The Great Discovery, and was initially set to replace Brandon and Michael Angelis in both narrations starting with the 12th season, but this fell through for unknown reasons.

In 2009, with the transition from models and sets to CGI, the series would move on to feature separate voice actors for the characters. The series' American and British dubs were both recorded in the United Kingdom, featuring the same pool of actors but in different roles for each dub, with some exceptions. Since the 16th season, many characters gradually began having the same voice actor in the US as the UK dub.
