Thomas & Friends (previously known as Thomas the Tank Engine & Friends) is the name of the television series based on the Railway Series by the Reverend W. Awdry. It was adapted for television by Britt Allcroft using the original stories from the Railway Series before using original stories written by independent writers. The series has been broadcast in over 185 territories and has spawned twenty-four series, a theatrical film, and fourteen specials.

The series was last produced by Mattel Creations taking over HiT Entertainment, who filmed the series since its acquisition of Gullane Entertainment in 2002.

In April 2008, it was announced that filming of the series would transfer to Nitrogen Studios in Canada and that it would be CG animated. CGI was first used during the twelfth series for the faces of the engines, people and animals, although characters in background shots would still have the traditional clay faces. The first CG production, Hero of the Rails was released in Autumn 2009. Since then, the series had been animated in full CG until the late 2010's.

In February 2012, it was announced that Arc Productions would take over animation duties starting with the seventeenth series in 2013. In August 2016, Arc Productions closed down after filing for bankruptcy. Jam Filled Entertainment, however, entered into an agreement, looking at acquiring the entirety of Arc. On 22nd August 2016, it was confirmed that Jam Filled Entertainment had successfully acquired Arc Productions and thus taken over the animation for Thomas & Friends.

A 2D-animated reboot and second theatrical film are currently in production, though it is currently unknown if the latter will have any connection to the main series.


Thomas & Friends was a television series mainly based around railway engines that live on the Island of Sodor. The show is mainly about the title character, Thomas, a cheeky little blue tank engine with six small wheels, a short stumpy funnel, a short stumpy boiler and a short stumpy dome. Thomas & Friends takes place on the standard gauge North Western Railway, the narrow gauge Skarloey Railway and the 15-inch gauge Arlesdale Railway. The head of the North Western Railway is Sir Topham Hatt, affectionately nicknamed "The Fat Controller" by the engines and staff, the Skarloey Railway is operated by Mr. Percival, "The Thin Controller" and the Arlesdale Railway is operated by Fergus Duncan, "The Small Controller."



The first known attempt to make a television adaptation of the Railway Series books was by the BBC in 1953. It was decided that Hornby Dublo models would be used and everything went ahead but the project did not succeed. During the live airing of the first episode, Henry derailed and a hand was seen coming down to put him back on the tracks. Nothing else is known to remain of this project.

There have been several other attempts, however. The first somewhat successful run was on the children's show "Jackanory" in 1970. The Railway Series books were read out loud by host Ted Ray. Five books were read in all until 2nd October 1970.

The current television series got its start in 1979 when the Reverend Awdry was interviewed on the Bluebell Railway for a feature on steam engines. The producer, Britt Allcroft, had read some of the books before the interview. She had become fascinated with the characters and after getting funding from her local bank, acquired the series so she could adapt it for television.

Thomas the Tank Engine & Friends (1984-1999)

Allcroft rounded up a production crew, which included model director David Mitton, narrator Ringo Starr and composers Mike O'Donnell and Junior Campbell. The first series premiered in October 1984 and with its success, came a second series in 1986.

After the huge successes of the first and second series, Britt Allcroft set another goal: bringing Thomas into the United States. Due to stricter broadcasting schedules, Britt had to create a half hour programme to go with the five and a half minute episodes. The result was Shining Time Station, starring Ringo Starr as Mr. Conductor, which began airing in 1989. This was another hit for Allcroft and was the beginning of the "Thomas craze" in America.

When the television series returned in 1991 with the third series, there were some big changes. Instead of following closely to the Railway Series, Allcroft and Mitton loosely adapted many of the Reverend's stories as well as loosely adapted magazine stories written by the current head writer Andrew Brenner (who unfortunately did not get credited for these adaptations), they even wrote their own episodes, much to the Reverend's disdain. The fourth series, airing in 1995, only had one original episode however and featured many new characters such as the Skarloey Railway engines.

By now, the series was doing incredibly well and a full-length theatrical film soon loomed ahead. Britt Allcroft decided to drift completely away from Railway Series stories and in 1998, the fifth series, contained all original storylines, allowing Britt to showcase the series as her own before the upcoming film.

Thomas' First Feature Length Movie (2000-2003)

The full-length theatrical film gained the title, Thomas and the Magic Railroad, and after many changes from the original script, it premiered in July 2000. The film recieved mixed to negative reviews from critics, and becoming a huge box-office failure - forcing Allcroft to step down from her position as a Deputy Chairperson. Her company was sold to Gullane Entertainment and they, in turn, were later sold.

In 2001, the idea for a spin-off focusing on the non-rail vehicles was being tossed around at Gullane. It is possible that this idea later became Jack and the Sodor Construction Company. During the process, the sixth series was produced and aired in 2002, as was the seventh in 2003.

Making Tracks to Great Destinations (2004-2012)

The buyer of Gullane Entertainment turned out to be HiT Entertainment and the eighth series, that aired in 2004, came with drastic changes. The episodes became more formulaic in plot with the focus on morals and education. Since the eighth series this format is still being carried out for all the following series with great success.

2005 saw the broadcasting of the ninth series as well as the release of the first direct-to-DVD special, Calling All Engines! The tenth series aired in 2006 and was the only production to contain twenty-eight episodes unlike the usual twenty-six. The first broadcasting of the eleventh series took place in 2007 and this marked the final series to contain twenty-six episodes, until the seventeenth series. The second direct-to-DVD special, The Great Discovery was released in 2008 and this marked the final full live-action production.

One of the most revolutionary steps in the show's history also took place in 2008, when it was announced that Thomas & Friends would be produced using computer generated imagery (CGI). The show would be produced in Canada at Nitrogen Studios and the twelfth series used CGI for the faces of the engines, the people and the animals alongside the traditional live-action format. This was also the first series to contain twenty episodes and this format continued until the seventeenth series.

The first fully CG animated production was the 2009 direct-to-DVD special, Hero of the Rails, directed by Greg Tiernan. This was also the first time the engines and people had individual voice actors since Thomas and the Magic Railroad. The voice acting continued for all series and specials hereafter.

2010 saw the first year to have two series, the thirteenth and fourteenth. Another feature length special, Misty Island Rescue, was released that Autumn. The fifteenth series premiered in early 2011 and the next direct-to-DVD special, Day of the Diesels, was released in Autumn 2011. During that October, Mattel won HiT Entertainment in an auction by Apax Partners, HiT's owners and in February 2012 the money was transferred. February 2012 also saw the premiere of the sixteenth series in the UK. It was the last series animated by Nitrogen Studios, the last to have Sharon Miller as the head writer and the final series to contain twenty episodes. Blue Mountain Mystery was released in September 2012. It was the last special to involve Nitrogen Studios and Miller.

A second theatrical film, supposedly titled The Adventures of Thomas, was set to be released in 2011, but years later and still with no news on any further developments, it is unknown whether the project will actually move on. Although there has been no official confirmation of the project's cancellation, it is presumable that the film has been scrapped.

Back On Track (2013-2017)

2013 saw Andrew Brenner take over as head writer and Arc Productions take over the CG animations, animating the seventeenth series as well as all following series and specials until the end of the show. The seventeenth series also regained the initial twenty-six episode format and implemented a new writing style that promised to focus on the original charm and appeal of Thomas & Friends. This format was used with great success and a lot of fan approval. Ten episodes of the seventeenth series aired in the UK in June 2013 followed by five episodes in September/October 2013. Another episode aired in November and four more in December. Also released in Autumn 2013 was the seventh direct-to-DVD special, King of the Railway. The seventeenth series began airing on 7 October 2013 in the US. The remaining six episodes of the seventeenth series, featured on the Spills and Thrills DVD aired between July and November 2014 in the UK. In Autumn 2014, the eighteenth series aired and the following feature-length special, Tale of the Brave was released. The remaining six episodes of the eighteenth series featured on the Dinos and Discoveries DVD premiered in the UK in July 2015.

Thomas & Friends celebrated their 70th Anniversary in 2015. To celebrate this milestone, a 44-minute special, The Adventure Begins was released in Spring 2015, the first feature to include original stories by the Rev. W. Awdry since 1995. Furthermore, a special 28-minute documentary, titled 70 Years of Friendship was released exclusively on the Thomas & Friends YouTube channel on 14 July 2015. In Autumn the same year, the next direct-to-DVD special, Sodor's Legend of the Lost Treasure, was released. The first four episodes of the nineteenth series premiered in the UK between 21 September and 24 September 2015. The nineteenth series also first aired on 13 October 2015 in the US.

In January 2016, three more episodes from the nineteenth series aired in the UK, followed by another five episodes in March 2016. March 2016 also saw the release of six more nineteenth series episodes released on the annual mini-tentpole, episodic release, Start Your Engines!. These episodes later aired in the UK in July 2016. A special 4-D theme-park exclusive production was released titled Thomas & Friends in 4-D: Bubbling Boilers on April 9, 2016 in Boston.

In August 2016, Arc Productions closed down after filing for bankruptcy. After entering an agreement, Jam Filled Entertainment looked to acquire Arc Productions under a new management. On 22 August 2016, it was confirmed that Jam Filled had successfully acquired the entirety of Arc Productions and some former Arc staff regaining their jobs, resumed working on animation for Thomas & Friends under the new management and organisation name.

September 2016 saw the release of the next direct-to-DVD special, The Great Race. The twentieth series began broadcasting in the UK on 5 September 2016 with the first five episodes of the series and in the US on the October 21, 2016. HiT Entertainment and SiF released a poll in which fans voted for what they wanted to see rendered in CG for this series. Notably, this was the first series since the fourth series to adapt Railway Series stories, with the book Small Railway Engines being adapted into the final three episodes of the series.

In 2017, a special entitled Journey Beyond Sodor aired in the autumn. The twenty-first series also premiered in autumn 2017 and it is the first series entirely animated by Jam Filled Entertainment. The series was cut short in order to allow for development of the twenty-second series. This series saw the addition of more slapstick humour and fast pacing in an effort to ease audiences into the soft reboot that occurred the next series.

Big World! Big Adventures! (2018-2020)

In 2017, it was revealed that the series would be undergoing a drastic revamp. The name of the series was changed to Thomas & Friends: Big World! Big Adventures! beginning with a special of the same name, which was released theatrically in the UK in the summer of 2018. The movie and the first half of the twenty-second series revolve around Thomas travelling the world and learning about different cultures, while the second half takes place on Sodor. The theme song was changed to Big World! Big Adventures!, the visuals became faster-paced, there is a greater emphasis on comedy and action, animals became a more prominent feature of the stories, and fantasy sequences became more prevalent, with at least one fantasy sequence in every episode. The show no longer features a narrator at all, replaced with Thomas speaking to the audience. Additionally, it was revealed that Edward, Henry, and Toby would be removed from the Steam Team, while the former two would be replaced with new female engines named Nia and Rebecca in an effort to bring the gender ratio among the main cast to a 50/50 split. It was announced that the episodes' runtime would be split into 7-minute stories (shortened from the 9-minute time slot used from series 13-21) and 4-minute segments featuring songs, puzzles, and other activities. These changes were made in an attempt to keep Thomas & Friends relevant by making it more similar to other preschool shows.

Following this drastic retooling, Thomas and the new Steam Team made their special online video appearance wearing Pudsey Bear ears for the BBC's Children in Need on November 9, 2018. Further upgrades were done to five out of seven Steam Team characters including Thomas, Percy, Emily, James and Gordon ahead of the twenty-third series aired in the autumn of 2019. In the summer of that year, Digs & Discoveries premiered at Drayton Manor's 4D cinema for a week before it was released on DVD and shown on television. By the beginning of 2020 for the 75th anniversary, Thomas & Friends had move from cable television on Nickelodeon in the USA to streaming exclusively on Netflix starting with Steam Team to the Rescue.

During the celebrations, Thomas and the Royal Engine was shown with a live-action introduction of Prince Harry followed by the twenty-fourth series and Marvellous Machinery, which marked the final productions for the original television series by a grand total of 584 episodes, 13 feature length specials and a theatrical film.

By October 2020, Mattel announced their collaboration with Corus Entertainment's Nelvana Studio to produce a full on 2D animated reboot titled 'Thomas & Friends: All Engines Go' which was broadcast during the autumn of 2021, and taking a completely different direction from the original show, while a live action and animated hybrid theatrical film is set to be directed by Marc Forster.
