Disney XD's Lab Rats Wiki
Mr. Davenport made us superhuman, because when all else fails, we can't.
Chase to Leo

"Rats on a Train" is the 5th episode in Season 1 of Lab Rats. It first aired on March 19, 2012. It features Adam, Bree, Chase, and Leo's first mission and first mention appearance of Caitlin.


The Lab Rats get their first mission to stop Davenport's high-tech super fast train from speeding out of control. Leo sneaks along, but when the Lab Rats discover he accidentally discarded the braking system they were supposed to install, they must improvise a way to stop the train before it crashes into a nearby town. Meanwhile, Tasha is given her big break at the TV news station when her boss asks her to cover the runaway train. She misses to see the train and fails the report. After Leo stops the train, Tasha finds out and she grounds Leo for two weeks in his room without television, video games and leaving the house, but Leo shortens his grounding to one week by tricking Tasha.

If you didn't waste your life watching cartoons every day, we might all be dead right now.
— Chase to Leo
Well, if I were to build a high-speed train, the first thing I would have put in was a cup holder. Oh! And one of those bumper stickers on the back that says, "I brake for cows."
— Adam
Bree: We can't quit now.

Chase: If we do, it means we failed our first mission.

Adam: Yeah, we've been training our whole lives for this moment now. I'm not giving up.

— Adam, Bree and Chase to Leo
We put ourselves in danger for the sake of humanity.
— Bree
We're all in this together. I may not be superhuman, but it doesn't mean I can't be a hero.
— Leo
Donald: Leo, just because you can't go on the train doesn't mean we can't have fun here. I'll... I'll pop in the Goober the Spunky Caboose DVD for ya!

Leo: I'm fourteen.

Donald: Okay, then pop it in yourself!

— Donald and Leo
Leo: I can handle extreme cold.

Donald: Leo, you get brain freeze from chewing mint gum.

— Leo and Donald
Bree: Leo, this is too dangerous for you.

Leo: Please. My middle name is "Danger."

Adam: Thought it was "Francis."

Leo: (levelly) It's pronounced "Danger."

— Bree. Adam, and Leo
I don't have morning breath. It smells like that all day.
— Adam
Donald: My auxiliary decelerator will stop anything - ocean liners, freight trains, tanks, eighteen-wheelers, twelve-wheelers...

Leo: Does it stop unnecessarily long explanations?

Donald: (glares at Leo) Apparently so.

— Donald and Leo
I just spent four hours in a bag without a bathroom. I think my support goes without saying.
— Leo
Leo: The answer is simple: If Sally's on a train traveling at a certain speed - X, she's gonna reach the curve at a certain speed - Y. All we need to do is multiply X by Y to find out if we have enough track left to stop.

Chase: Okay... but what if Sally is sitting on enough nuclonium to reduce an entire city to a stain?

Leo: Well, then Sally should've taken the bus!

— Leo and Chase
Leo: So, what's our next mission? A runaway rocket or a sinking battleship?

Chase: How about trying to explain this entire thing to your mom?

Leo: That's a mission we'll never return from.

— Leo and Chase
