Eleven-year old Lily (Mara Wilson) sets off to see her grandpa (Peter Fonda), but she ends up on the wrong train. Lily meets Mr. Conductor (Alec Baldwin), who lives in the town of Shining Time. Mr. Conductor uses magic gold dust to visit the Island of Sodor and Thomas the Tank Engine and the Magic Railroad. When Lily arrives, Thomas is having problems with Diesel 10, a renegade diesel engine, and Mr. Conductor is running out of the magic dust. But all will be well if Lady, a missing golden engine, can be found. In the meantime, Grandpa has an engine hidden away in the mountain. Could it be Lady? Will Mr. Conductor find more magic gold dust? And will Thomas again be the number one hero of the Magic Railroad?
In the early 1980s, Britt Allcroft found Thomas the Tank Engine and his friends in the Reverend W. Awdry's THE RAILWAY SERIES and brought them to television. Now--aiming at an audience of children between 3 and 7 years old--Allcroft transfers Thomas and his friends to the big screen, and she uses all manner of special effects in capturing the storybook feel of the original stories.
