Britt Allcroft (born Hillary Mary Allcroft, on 14th December 1943 in Worthing, Sussex, England, United Kingdom) is an English-American producer, writer, director, and actress who is the multi-award-winning creator and adapter of Thomas the Tank Engine and Friends (based on the Railway Series by Wilbert Awdry) and Shining Time Station.

She founded "The Britt Allcroft Company" with then-husband Angus Wright (they were married from 1973 to 1997), known as Britt Allcroft Limited (later renamed Gullane Entertainment) which was sold and acquired by HiT Entertainment in 2002. Allcroft is well known for her creation of Thomas the Tank Engine and Friends, its American counterpart Shining Time Station and its spinoffs.

She was also the screenwriter, a producer, and director of Thomas and the Magic Railroad, and supplied the voice of Lady. She also created the television show "The Magic Adventures of Mumfie" and in the late 1990's remade the classic series "Captain Pugwash" and Serves as The head writer of season 25.

She currently lives in Santa Monica, California.


Allcroft served as executive producer for the first two seasons. She took Robert D. Cardona's place as producer from the third to fifth seasons after Clearwater Features closed down in 1990. In May 2000, Allcroft was a director and advisor of Gullane and returned for the sixth season as executive producer alongside Peter Urie and had script consulting duties on the seventh season. But by 2003 (a year after Gullane Entertainment was sold and acquired by HiT Entertainment), Allcroft had resigned from her remaining positions with the company and did not return for the eighth season. This was attributed to the poor reception of Thomas and the Magic Railroad. She also served as "Storyteller Director" for the show. She also worked on a live-action kids show called "The Scoobs" and created an animated show for Disney Junior called "Whisker Haven Tales with the Palace Pets".

Allcroft and Rick Siggelkow are currently trying to get Shining Time Station onto DVD or back on television. She is also working on reviving "The Magic Adventures of Mumfie".
