Thomas and the Magic Railroad

Thomas the Tank Engine's feature film debut follows Thomas and Mr. Conductor (Alec Baldwin) as they cross between the real world and the fictional Island of Sodor, in an attempt to recover lost gold dust.
Mr. Conductor's supply of magic gold dust, which allows him to travel between Shining Time and Thomas's island, is critically low. Unfortunately, he doesn't know how to get more. Meanwhile, Thomas is fending off attacks by the nasty diesel engines. Getting more gold dust will require help from Mr. C's slacker cousin, his new friend Lily and her morose grandfather, plus the secret engine.
