In this one-hour special, the Conductor has a special surprise for our favorite Pteranodon Family, the Dinosaur Drill Train! This amazing machine gives its passengers a front row seat as they dig deep underground on a once-in-a-lifetime adventure below the Earth's surface. There they discover a whole new world from fossils and troglobites to rivers of lava. The family gains a whole new perspective on our planet and what it's made of especially after a runaway mine cart thrill ride!
