James is the vain red engine, number five, from the Thomas the Tank Engine universe created by the Reverend W. Awdry. This scream comes from Thomas and the Magic Railroad, the franchise's first theatrical film released in 2000, during one of the story's frightening moments. Fans ripped short audio moments from the movie and shared them on soundboard sites, where the exaggerated panic stood out. It endures because the Thomas fandom is huge and the scream works as a cartoonish reaction far beyond train videos.
