Clara: Emmett! Emmett! Emmett!
Clara sees the model Doc used to demonstrate the plan. She sees the model DeLorean.
Clara: (reading) Time machine.....
Doc and Marty meanwhile are chasing the train on their horses. Doc manages to climb on the last carriage.
Doc: C'mon Marty!
Marty: Argh, argh!
Doc: Ah, gimme your hand!
Doc grabs Marty's hand and pulls him onto the train. They both fall over on each other.
Marty: Argh! Whoa! Whoa! Argh!
Meanwhile Clara is following them on her horse. Doc and Marty runs across the roofs of the carriages.
Doc: Wa-ha!
Marty: Whoa!
Doc: Hoo! C'mon, Marty!
Marty jumps onto another car.
Marty: Argh!
Doc: C'mon, let's go! Masks on.
By now they're on the tender. They pull their bandannas over their mouths and climb over the tender, before dropping into the cab of the locomotive. Doc is holding a gun.
Doc: Reach!
The engineers (the same one we spoke to at the station a few days earlier, plus another one) put their hands up.
Engineer: Is this a holdup?
Doc and Marty look at each other.
Doc: It's a science experiment! Stop the train before you hit the switch track up ahead.
The train stops. Marty jumps out and changes the points.
Marty: Doc!
He holds his hand up. Doc points his gun at the engineers.
Doc: Uncouple the cars from the tender.
They do so, and Doc starts the train. Marty jumps on as it passes him. Doc pulls the whistle on the train.
Doc: I've wanted to do that my whole life!
Marty laughs.
