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.

Kids these days demand cutting edge special effects or at least a clever plot with cute charectors. This movie has neither, having lost in its Americanization what the British original did so right.

'Thomas and the Magic Railroad' delivers an uplifting, feel-good story with nostalgic charm that some families treasure, but the film suffers from severely flawed writing with an indecipherable, disjointed plot and wooden acting, particularly from Peter Fonda. Engagement is sharply divided—some young children were entranced while others found it boring or frightening. The adaptation disappointed fans by losing the original English charm, though a few appreciated its gentle simplicity for young audiences.
