Thomas and the Magic Railroad is a 2000 children's fantasy adventure film written and directed by Britt Allcroft and produced by Allcroft and Phil Fehrle. It is the only theatrical live-action/animated Thomas & Friends film in the franchise. The film stars Alec Baldwin as Mr. Conductor, Peter Fonda, Mara Wilson, Didi Conn, Russell Means, Cody McMains, Michael E. Rodgers, and the voices of Eddie Glen and Neil Crone. The film is based on the British children's book series The Railway Series by the Reverend W. Awdry, its televised adaptation Thomas & Friends by Allcroft, and the American television series Shining Time Station by Allcroft and Rick Siggelkow. The film tells the story of Lily Stone (Wilson), the granddaughter of the caretaker (Fonda) of an enchanted steam engine who is lacking an appropriate supply of coal, and Mr. Conductor (Baldwin) of Shining Time Station, whose provisions of magical gold dust are at a critical low. Lily and Mr. Conductor enlist the help of Thomas the Tank Engine (Glen), who confronts the ruthless, steam engine-hating Diesel 10 (Crone) along the way.

Thomas & Friends is a media franchise created by Rev. W. Awdry and Britt Allcroft. The franchise revolves around a railway, called the North Western Railway, located on the fictional Island of Sodor. The current title character of the franchise is Thomas the Tank Engine, an anthropomorphised steam locomotive, who works with other engines, including Edward, Henry, Gordon, James, Percy, Toby and many others. The franchise began with stories told from Wilbert Awdry to his son. In 1984, it was turned into a television series, which spawned a reboot series, titled Thomas & Friends: All Engines Go.
