Tosha: [wearing an engineer hat] When I grow up, I think I want to be a railroad engineer! I'd drive that train down those tracks, blow that whistle...
[she blows the train whistle, and as she does, Barney comes to life, and then Baby Bop and BJ arrive too]
Barney: Has the train arrived?
B.J.: Did I hear a train?
Baby Bop: Oh where's the train? Hi everybody!
B.J.: Hi guys!
Baby Bop: I didn't see the train. Where's the choo choo train?
B.J.: Yeah, I don't see any train. I wanna go for a ride!
Tosha: That wasn't a train you heard. That was me. Listen.
[she blows the whistle again, and the dinosaurs groan in realization]
Barney: I thought the surprise was here.
Kenneth: Surprise?
Barney: Yes. It's coming on a train today.
Tosha: A train?
Julie: Trains don't go by our school, Barney.
Barney: But if we use our imaginations, maybe they will. Listen.
[train whistling sounds in the distance, and everyone realizes what is happening]
B.J.: Wow. Did you hear that? It's a train.
Julie: Let's go!
[the kids follow the sound outside, the dinosaurs join them, and the outing begins]
