Cerberus: (as Casey Junior, Thomas, and Emily puff out of the buffers, and comes to a complete stop behind Bahia Train) Ah-ha! There's that engine and his crew! And look who's he's with! Guys, come and destroy!
Samson and The Train: Oh, no. You do it yourself. We don't like. Yeah, we mean it. Excatly. I have no idea. Good words!
Casey Junior: Run, Bahia!
Thomas Bandicoot: Quick!
Emily Bandicoot: Casey, Thomas, and I will help you!
Inspector Gadget: So will I, Bahia, I'll not let you down again.
Cerberus: Ha! Who needs Samson and The Train?
Mario: (as Bahia with her wagons and Casey with his coaches and caboose set off with Cerberus laughing evilly and chasing them) Watch out for the viaduct. It's dangerous. Ah-ha!
Luigi: What's wrong, Mario?
Mario: Bahia Train. That engine's name is Bahia Train. She's part of the clue to the source...
Mario and Luigi: (together) of The Gold Dust! (they scream in terror)
P.T. Boomer: (squeals like a chicken and lands on Cerberus's roof) That makes two of us!
Cerberus: Now I'll get you and those engines, Inspector Gadget!
Inspector Gadget: No, you can't, because the magic you refuse to believe in, will get the better of you.
P.T. Boomer: You can run, but cannot hide, right, big boy?
Cerberus: (laughs evilly) I'm coming to get you.
Casey Junior, Thomas Bandicoot, and Emily Bandicoot: Oh, get back! Run away! Retreat!
Inspector Gadget: Come on, Bahia Train.
Cerberus: Coming, puffballs! (laughs evilly) Look out! Here I come! Duck, P.T. Boomer! (laughs evilly as poor Thomas Bandicoot and Emily Bandicoot continue to stoke the boiler with lots of coal into Casey's boiler)
P.T. Boomer: I like my lunch steam! (laughs)
Cerberus: Come here, I'm gonna eat ya. (The three engines race over while 171 Slieve Gullion with five red coaches and two blue and yellow coaches puffs past) You're pretty fast for two steam engines, eh? (While otherwise occupied in racing from Cerberus, the nightmare train is about to hit another train behind No. 461, a 4-6-0 tender engine, which is pulling one green coach, one blue and yellow coach, and five red coaches)
Inspector Gadget: (gasps when he sees the other train approaching them with the bridge collapsing) Well, Bahia, this is your shining time too.
Bahia Train: I hope so.
Casey Junior: Come on, Bahia, you can do it, little engines can do big things. (Casey and Bahia puff as hard as they can and have finally made it over the bridge)
Inspector Gadget: Well done, you guys! Well done! (blows the whistle as Thomas and Emily do the same)
Cerberus: Hold it. Oh, what's going on? Hang on. Hold it, wait a second... (screams in terror and grabs onto another broken bit of the track to let No. 461 with its green coach and blue coach and red coaches puff safely across the bridge)
P.T. Boomer: You puff ball, teapot, and tin-kettles! (he and Cerberus fall into the barge's wagons after 4-6-0 No. 461 with the green coach, with blue and yellow, and red coaches makes it safely across)
Cerberus: Ah, oh, well. Next time of year for the cruise. (P.T. Boomer laughs)
Casey Junior: Super Mario, you still don't have your gold dust.
Bahia Train: I think he will soon.
Mario: Wait a minute... Then watch the swirls that spin so well.
Pinocchio: Swirls, just like the ones, just like the Bahia Train, who is on the railroad.
Penny: Is there anything else?
Luigi: Of course, it's a well, and well means water.
Mario: Put the magic in the water.
Inspector Gadget: Go ahead, Penny, throw it up in the air.
Mario and Luigi: Please... Please...
Casey Junior and Bahia Train: Now, Penny! (Penny obeys)
Mario, Luigi, Penny, Pinocchio, Inspector Gadget, Brain, Casey Junior, Bahia Train, Thomas Bandicoot, and Emily Bandicoot: Gold dust! (Mario and Luigi get their gold dust back)
Casey Junior: Bahia, you're a really helpful engine.
Bahia Train: And helping each other, brings the magic to life, in all of us.
Pinocchio: Come on, Brain, let's take a look around here.
Luigi: Penny, I think I've promised you. Here. Take some. (Penny puts the gold dust on Tweety) So, Mario, how else can I help?
Mario: You mean you can't go back to the beach?
Luigi: Nah... Maybe for a hoilday. I'm ready to work. You've got a job for me?
Mario: You know, bro, this is a railroad, with palm trees and a spell and a sunshine with sunny spells.
Luigi: What's the way?
Mario: This is the way. (Luigi fades away as Mario picks up the flower bells) Hello? Oh, yes, Mickey Mouse, sir. You're on your way back right now. Splendid, I'll be at the sheds to welcome. Everything is under control. Well, see you in Shining Time Station. (blows his whistle and vanishes)
Penny: Here, Uncle, I like you to have this.
Inspector Gadget: Well, how sweet of you, Penny. Here, give me Tweety. I think we can share it. Now we'll always remember our Shining Time together. (Now that the entire Fantasyland and Fairytale Railway Traction Company Limited Island is back to normal, everyone can have a good time, eating and drinking lots of things)
Mario: (as Casey with his coaches and caboose puffs away with Bahia) And so we've come to the happy end of our story, and it's time for all of us to go home, just like Casey and Bahia and all of their friends as well.
Narrator: The End. (The Really Useful Engine, Locomotion, & Shining Time songs play at the end of the film)
