Main characters
Buddy Tyrannosaurus
Voiced by: Phillip Corlett (seasons 1-2), Sean Thomas (season 3), Dayton Wall (season 4), Chance Hurstfield (season 5)
Debut: Season 1 episode 1a "Valley of the Stygimolochs"
Debut: Season 1 episode 1a "Valley of the Stygimolochs"
A friendly and precocious T. rex adopted by the Pteranodon family.
- Adorably Precocious Child: He knows a lot about dinosaurs for his age, and sometimes acts more mature than he really is.
- All-Loving Hero: Owing to Buddy being adopted by Pteranodons, he is quite open-minded, friendly, and idealistic. He tries to make friends with and understand every character in the series. In "The Egg Stealer?" he defended Keenan when the latter was accused of stealing eggs, despite the fact that Keenan is a bully towards him.
- Big Little Brother: Tiny is the oldest and smallest of the Pteranodon siblings, whereas Buddy is the youngest but, by virtue of his species, will grow up to become the largest.
- Character Catchphrase:
- "I have a hypothesis!" Usually followed by Tiny (or another character) saying a variation of, "That's an idea you can test."
- "Do you mind if we compare features? It's kinda my thing."
- Child of Two Worlds: He gets along with the Tyrannosaurus family just fine, but he feels conflicted about the possibility of leaving his adoptive family behind when he grows up.
- Commonality Connection: Buddy becomes fast friends with Annie due to them both being T. rexes.
- Constantly Curious: Buddy always wants to learn new things.
- Fish out of Temporal Water: Pteranodon lived about 20 million years before Tyrannosaurus, and the learning segment for "Great Big Stomping Dinosaur Feet" even points out that that T. rex didn't live at the same time as the other Pteranodon Terrace locals. The Dinosaur Train travels through a time tunnel whenever the family visits Rexville. Together, these imply that wherever Buddy came from, his egg wasn't laid in the same epoch that he lives in.
- Happily Adopted: Despite the fact that Buddy is a completely different species than the rest of his family, they love each other the same.
- I Am Who?: The first few episodes focus on Buddy trying to figure out just what type of dinosaur he is.
- Interspecies Adoption: Buddy is a T. rex raised by Pteranodons.
- Leitmotif: His music theme is a steel drum beat (or at least an instrument similar to that).
- Nice Guy: He wants to be friends with everyone.
- The Nose Knows: Buddy has a great sense of smell. This is one of the clues to the fact that he is a T. rex.
- Orange/Blue Contrast: He is orange and also has blue stripes on his body.
- Terrifying Tyrannosaur: His song "I'm a T. rex" is about how Tyrannosaurus is the biggest and most fearsome predator in his part of the Cretaceous.
- Trademark Favorite Food: He loves carrion.
- Token Flyer: Inverted. He's the only member of his family who can't fly.
- Vibrant Orange: Buddy is an orange Tyrannosaurus with blue stripes. His defining character traits are his curiosity and willingness to learn about other dinosaurs and time periods. Hence, he tends to come across as quite extroverted and excitable, although he does show signs of being shy at times.
Tiny Pteranodon

Debut: Season 1 episode 1a "Valley of the Stygimolochs"
The oldest of the Pteranodon siblings, Tiny is a clever and courageous companion on Buddy's adventures.

- Plucky Girl: Tiny is smart, brave, and has high confidence when she meets new dinosaurs. Tiny is so brave that she often wanders off a little too far, but Buddy is always there to help her get back on the right track.
- She's a Man in Japan: Tiny is a boy in the Czech dub.
- Tomboy and Girly Girl: Tiny is the tomboy to Shiny's girly girl. Tiny loves going on adventures.

A bit of a show-off, Shiny is the second-oldest of the Pteranodon kids. She loves shiny things and prefers to stay home while her family goes on the Dinosaur Train.

- Cannot Spit It Out: Shiny is unable to confess how she truly feels to Gilbert.

- Meaningful Name: True to her name, Shiny likes collecting shiny things like shells.
- Primal Fear: Shiny is badly afraid of the dark and doesn't react well in "Mom Was a Kid Once" when Annie asks her to join her in exploring a deep, dark cave. She eventually flies away in terror and returns to the nest, saying she's done playing with Annie for the day, and possibly forever.
- Shrinking Violet: She can be rather timid in social situations.
- Signature Laugh: She snorts when she laughs.
- Team Mom: Since Shiny is the second-oldest of the kids, she often tries to be the 'mom' of the bunch by bossing the others around. As you can tell, she isn't quite good at it.

- Good Parents: He's a supportive father.
- Happily Married: Loves his wife very much.

The Conductor / "Sonny Boy"
- Voiced by: Ian James Corlett
Debut: Season 1 episode 1a "Valley of the Stygimolochs"
The intelligent and warm-hearted conductor of the Dinosaur Train, and a friend to the Pteranodon family.
- Character Catchphrase:
- "Time Tunnel Approaching!"
- "Tickets Please!"
- "All aboard!"
- "Bless my scales and feathers!"
- Everybody Calls Him "Barkeep": Everyone calls him "the Conductor" except his mother and Thurston.
- Figure It Out Yourself: It's strongly implied that the Conductor always knew that Buddy is a Tyrannosaurus rex and could have just told him, but let him figure it out for himself because he knew it would mean more to him than for him to just tell him.Conductor: Yep. I had a feeling he was a T. rex.
- Half-Dressed Cartoon Animal: While most of the dinosaurs are naked, he wears a hat and vest.
- Have I Mentioned I Am a Dwarf Today?: In nearly every episode, the Conductor reminds the kids of one of his Troodon traits, such as his large toe claw, his intelligence, or his night vision.

- Interspecies Romance: He's in love with Erma Eoraptor.

- Only Known by Their Nickname: His mother and Thurston call him "Sonny Boy" in a doting and condescending way, respectively, suggesting it's a diminutive nickname.
- Rail Enthusiast: He absolutely loves trains, especially the Dinosaur Train. One episode even features him singing about his love for trains.
- That Reminds Me of a Song: Mr. Conductor often says that something reminds him of a song, but is hesitant to sing unless the kids beg him.
- Time-Travel Romance: An extreme example; the Conductor — a Troodon, one of the last dinosaurs, is in a relationship with Erma — an Eoraptor, one of the first dinosaurs. They live over 160 million years apart — the same time difference as it would be if, say, a Stegosaurus started dating a HUMAN — but it's very clear that they love each other.
