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! Buddy and Tiny give Elliot Enantiornithine, a first timer on the Dinosaur Train, a tour of the Train. When they go through Laura Giganotosaurus' car, she explains to them that today is her bird watching/drawing day, but she hasn't found a single bird to watch. But, there's Elliot. He hams it up for Laura, who watches and draws him. This is so fun that Buddy and Tiny bring Laura to meet another bird friend-- Arlene Archeopteryx. Then Arlene and Elliot introduce the kids and Laura to a new bird named Peng Protopteryx! It's a successful birdwatching/drawing day as all three birds are delighted to show off their unique feathers.
