Marty: Right, and take care of that baby!
He and Doc ride off.
Seamus: I will!
Clara runs down the street and enters Doc's shop.
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.

We see the DeLorean. In the background the train appears and stops just before it would hit the DeLorean. Marty and Doc grab coloured logs and put them in the fire.
Marty: What are these things, anyway?
Doc: My own version of Presto Logs. Compressed wood with anthracite dust chemically treated to make the fire burn hotter and longer. I use them in my forge. These three will light the fire sequentially, make the fire burn hotter, kick up the boiler pressure and make the train go faster.
Meanwhile Clara sees the coaches by themselves on the track, and guesses that Doc has the locomotive. She gestures to her horse to move.
Clara: Hiyah!
Marty is in the DeLorean. Doc is in the train. Doc blows the whistle and the train starts to move. It bumps into the DeLorean, which also starts to move. Marty and Doc speak to each other through walkie-talkies, as before this will be denoted by (w.t).
Marty: (w.t) Ready to roll!
Clara can now see the train, but Marty and Doc can't see her.
Clara: Emmett!
Cut to Marty in the train.
Doc: (w.t) Marty. are the time circuits on?
Marty turns them on.
Marty: (w.t) Check, Doc.
Doc: (w.t) Input the destination time - October 27th 1985, 11am.
Marty does so, then checks the speed.
Marty: (w.t) We're cruising at a steady 25 miles an hour, Doc.
Doc: (w.t) I'm throwing in the Presto Logs.
One by one, Doc throws them in.
Doc: (w.t) Marty, the new gauge will show the boiler temperature. The colour coding indicates when each log will fire. Green, yellow, and red. Each detonation will be accompanied by a sudden burst of acceleration. Hopefully we'll get up to 88 miles per hour before the needle hits two thousand.
Marty: (w.t) Right, what happens what it hits two thousand?
Doc: (w.t) The whole motor will explode.
Marty: (w.t) Perfect.
Clara has caught up with the end of the train and manages to climb on. Cut to Marty.
Marty: (w.t): Hey, Doc, we just hit 35!
Doc: (w.t) OK, Marty, I'm coming aboard!
Doc climbs over the front of the train.
Clara: Emmett!
But Doc doesn't hear her. Cut back to Marty. He's looking at the speedometer.
Marty: Come on, come on. (screams into w.t). You better hold on to something, Doc, the yellow log's about to blow!!!
There is an explosion. Clara is thrown back a little bit and is stunned.
Clara: Ahh! (pause) Golly.
Cut back to Marty. The time circuits reveal the present time is 8.18am.
Marty: (w.t) We just passed 40!
Clara manages to get into the driver's seat.
Clara: Emmett! Emmett! Emmett!
Once again she is not heard. Cut to Marty. He opens the car door and looks at Doc.
Marty: (w.t) We just passed 45, Doc, go for it!
Marty looks at the speedometer again.
Marty: 50!
The train whistle blows. Both Marty and Doc are puzzled. Doc turns back to the cab and sees Clara, waving.

Clara: Emmett!
Doc screams with delight.
Doc: Clara!
Clara: I love you!
Marty: (w.t) Doc, Doc! What's happening??
