The film begins in the fictional town of Shining Time, where Mr. Conductor (played by Alec Baldwin), a magical railroad conductor, resides. Mr. Conductor is responsible for keeping the Magic Railroad running smoothly, which is powered by the mystical golden engine, Lady.
Meanwhile, on the island of Sodor, Thomas the Tank Engine (voiced by Eddie Glen) and his friends are preparing for the annual Great Railway Show. However, trouble is brewing as the evil diesel engine, Diesel 10 (voiced by Neil Crone), and his sidekick, the devious diesel shunter Splatter (voiced by Kevin Frank), plot to destroy the Magic Railroad and take over Sodor.
At Shining Time, Lily Stone (played by Mara Wilson), a young girl from the human world, discovers a mysterious gold dust that allows her to travel between Shining Time and Sodor. Lily learns about the Magic Railroad from her grandfather, Burnett Stone (played by Peter Fonda), a retired railroad engineer who has lost his faith in magic since Lady disappeared.
Lily teams up with Mr. Conductor and Thomas to restore the Magic Railroad and bring Lady back to life. Along the way, they encounter challenges and obstacles, including Diesel 10’s attempts to derail their plans and destroy Lady once and for all.
As Lily, Thomas, and their friends race against time to save the Magic Railroad, they learn the importance of courage, friendship, and believing in the power of magic. With the help of Lily’s belief and the magic of the gold dust, Lady is restored to her former glory, and the Magic Railroad is saved from destruction.
In a climactic showdown, Thomas and Lady join forces to defeat Diesel 10 and his cronies, sending them tumbling off the crumbling viaduct and saving the day.
