Britt Allcroft, the British producer and writer best known for adapting "Thomas the Tank Engine" into the beloved TV series "Thomas & Friends," has died at the age of 81 on December 25 in Los Angeles. Her daughter, Holly Wright, confirmed the news.

Allcroft was instrumental in taking Thomas, originally from children's books by Rev. Wilbert Awdry in the 1940s, to the small screen. The series debuted in 1984 on ITV as "Thomas the Tank Engine & Friends," captivating young audiences with its life lessons, catchy music, and endearing cast of anthropomorphic trains. Over time, it blossomed into a billion-dollar franchise, including films and theme parks.

In a 1995 BBC documentary, Allcroft noted, "Children need gentleness, comfort, and fun in their lives," showcasing her dedication to creating content that resonates with kids’ emotions. Her journey began while researching a documentary on railroads. Despite previous adaptations failing, her relentless pursuit for the rights paid off when she envisioned a series featuring a narrator true to Awdry’s books.

She even risked her finances, mortgaging her house to make her vision a reality, paving the way for the iconic show which aired for over three decades and became a staple of children’s television globally.
