Our Pteranodon family accompanies Mr. Conductor to the Troodon Town Roundhouse to meet up with Thurston Troodon, the Rocket Train's conductor. They all soon learn that Tricia Troodon, a young hotshot conductor, actually invited everyone there to see her new train - the Solar Train! The kids learn that it's powered by the sun! To test the train's performance, the three Conductors, along with the help of Buddy, Tiny, Shiny and Don, race the Dinosaur Train, Thurston's Rocket Train and Tricia's new Solar Train to the Triassic!
