Unfortunately, the Conductor's father never returned, and is apparently lost. The Conductor decides to take the new Drill Train and tunnel into the future to rescue his missing father!

Maurice helps them search through the icy wastes until they find a feather-covered Northern Troodon who turns out to indeed be Trevor, the father of Mr. Conductor! A happy reunion for all, and they bring him home to the Age of Dinosaurs.
