Psst.
Host (Adam Tex Davis)
Hey smarty pants. Recognize these sounds? Why, of course. It's your mom trying to feed you vegetables when you were three. Open wide.
Diesel Train (Dottie Diesel)
Here comes the train.
Host (Adam Tex Davis)
Choo choo. Just kidding. Those are the sounds of an actual train. And whether it's a freight train or a people train, trains have been around for more than 200 years. Have you ever ridden on a train? Maybe it was to visit another town or city or state, or maybe you rode a subway underground. Whether it's a long ride or a quick trip, riding the rails sure is something special. Did you know that there are more than 1.3 million km of train tracks covering the planet? That's more than enough track to travel to the moon and back, and then back to the moon again. That's one small choo choo for man
Subway Train (Sammy Subway)
and one giant chugga chugga for mankind.
Host (Adam Tex Davis)
Any guess which country has the most train tracks? Why, it's the United States, one of the first countries to get into the train craze. All aboard. But how do trains work? How fast can they go? And where can you ride a train that flies? All aboard. For another whiff of history and science, on who smarted? Who's smarted?
Subway Train (Sammy Subway)
Who's smart? Is it you?
Host (Adam Tex Davis)
Is it me?
Subway Train (Sammy Subway)
Is it science or history?
Host (Adam Tex Davis)
Listen up everyone.
Subway Train (Sammy Subway)
We make smarting lots of fun. But who's smart?
Host (Adam Tex Davis)
And hey smarty pants, have you ever seen or played with model or toy trains? Some train sets even have little towns and trees and people and railroad crossings. Clearly, trains and Railroads have fascinated people for a long, long time, way before the first locomotive. Rails themselves go back to ancient times. Early people discovered it's easier to move heavy carts if they're on tracks, instead of pushing them down muddy or uneven roads. Some of these ancient trackways, mostly made of wood, can still be found in places like England, Greece, Italy, and China. By the 1700s, tracks covered much of the world, especially Europe, where iron rails and wheels replaced wooden ones. But cars on those rails were usually pulled by horses. Smarty pants, do you know what inventors used to create the first self moving train? Was it A, electricity, B, water, or C, hot sauce? If you guessed B, you're correct. The first locomotive that used water in the form of steam to power its engine appeared in Great Britain in 1804. And look, here comes a steam locomotive right now.
Steam Engine (Steve Engine Steve)
Why, hello there.
Maglev Train (Maggie)
Whoa.
Host (Adam Tex Davis)
A talking train. Wait, are you Tom?
Steam Engine (Steve Engine Steve)
No, no, no. Don't say that name. I'm not him. I'm a completely legally acceptable knockoff. My name's Steve Engine Steve, hop aboard and I'll tell you whatever you want to know about trains.
Diesel Train (Dottie Diesel)
Ooh.
Host (Adam Tex Davis)
What do you think, smarty pants? Should we climb aboard this talking steam engine and learn about trains? Yeah, yeah. I know this couldn't actually happen, but just go with it. Okay, Steve, we're in. So, Steve, when did people first start riding trains?
Steam Engine (Steve Engine Steve)
Back when the steam engine was first invented, trains were primarily used for hauling coal, a substance found deep underground that was used to make power and heat. When engineers added passenger cars, people were nervous about riding them. They thought the train vibrations would shake them unconscious, or they'd be unable to breathe while traveling at such high speeds.
Host (Adam Tex Davis)
Wow. How fast did those trains go? As fast as a horse, an ostrich, a cheetah. Smarty pants. What's your guess?
Steam Engine (Steve Engine Steve)
Not quite. The first train zipped down the tracks at a whopping 10 miles per hour.
Host (Adam Tex Davis)
Did you say 10? 10 miles per hour?
Steam Engine (Steve Engine Steve)
Actually, it was a little less than that.
Host (Adam Tex Davis)
Lots of people can run faster than 10 miles per hour. Why were passengers so worried?
Steam Engine (Steve Engine Steve)
Ah, you know, new things sometimes make people nervous. But they got over it. And as steam locomotives became more popular, by the 1850s, they were moving much faster, too. 50 miles per hour or more around the speed people drive on a highway.
Host (Adam Tex Davis)
That's better. So how does a steam locomotive work?
Steam Engine (Steve Engine Steve)
It's quite brilliant, actually. You get a good fire burning in the firebox, which is right off the cab. Basically, the command center of the locomotive. That fire heats water in a nearby boiler to create steam. The Steam travels into cylinders on the train and moves rods called pistons which turn the wheels. The wheels travel on rails currently made of steel, a metal that can be easily shaped to handle curves. The rails were bolted to wooden or concrete supports called ties or sleepers, and are set parallel to each other a little less than five feet apart, creating the classic train track look. The tracks rest on loose gravel or stones, which keep them in place and help the train move swiftly to its destination.
Host (Adam Tex Davis)
And what's our destination today?
Steam Engine (Steve Engine Steve)
Depends. How much coal did you bring?
Host (Adam Tex Davis)
I didn't bring any coal.
Steam Engine (Steve Engine Steve)
Wood?
Host (Adam Tex Davis)
No wood.
Steam Engine (Steve Engine Steve)
Oil?
Host (Adam Tex Davis)
I have a banana.
Steam Engine (Steve Engine Steve)
Got any water?
Host (Adam Tex Davis)
Yes, I have my Houston water bottle, which incidentally is totally available at the
Steam Engine (Steve Engine Steve)
whosmarted merch store@whosmarted.com yeah, despite the shameless plug, that's not gonna be enough. Steam engines need a good supply of water. And to heat that water, you need to burn a lot of coal, wood, or oil. We're not exactly the most environmentally friendly trains. Sorry, trusty narrator. I'm gonna have to let you off at this station.
Host (Adam Tex Davis)
How do I get back?
Steam Engine (Steve Engine Steve)
There's a train across the platform. Bye now.
Host (Adam Tex Davis)
Oh, okay. Bye. Come on, smarty pants. I see another train.
Diesel Train (Dottie Diesel)
Hey, you need a ride?
Host (Adam Tex Davis)
Yes, I definitely do.
Diesel Train (Dottie Diesel)
Hop on. The name's Dottie. Diesel. Dottie.
Host (Adam Tex Davis)
Oh, hi, Dottie. Tell me, what makes a diesel engine different than a steam engine?
Diesel Train (Dottie Diesel)
First of all, I don't need no stinking wood or coal or oil to get me going. I run off of diesel fuel, which is like gasoline, but thicker. My engine burns that fuel to power a generator that creates electricity. That electricity gets my motor going, which turn my wheels, usually with more power than a steam locomotive. US Diesels are also cheaper to maintain and create less pollution than steam engines.
Host (Adam Tex Davis)
Go duddy.
Diesel Train (Dottie Diesel)
Yeah. Just think how much yucky stuff those steam trains spewed into the air we breathe. In the 1800s, they were going practically everywhere in the United States. Trains help connect cities and create more communities out west. Especially after the completion of of the transcontinental railroad in the 1870s. Suddenly, a trip from the Atlantic to the Pacific coast went from taking months to taking less than a week.
Host (Adam Tex Davis)
Whoa.
Diesel Train (Dottie Diesel)
The USA was once a world leader in rail transportation, but it's not anymore. Most people use planes and cars to travel long distances today, smarty pants, which
Host (Adam Tex Davis)
country now has the largest number of train passengers? Is it A, China, B, Germany, or C, India? If you said A China, you're right.
Diesel Train (Dottie Diesel)
Oh, and they got some high tech trains over there too. Real be, but diesel trains, like Me. We've been chugging around since the early 1900s. And we don't just carry passengers. A lot of us are freight trains that carry coal, foods, supplies, and other things to many communities. Something steam trains used to do. That is until US diesels and another type of train made steam engines practically obsolete.
Host (Adam Tex Davis)
Oh, yeah? What other kind of train is that?
Diesel Train (Dottie Diesel)
You'll find out here. Thanks for riding with me.
Host (Adam Tex Davis)
Oh, thanks, Dottie. Hmm. I don't know about that train over there. Hmm? I don't know about that train over there. It's got flames shooting out of it and bats flying all around. Uh, hello? All aboard. Yeah, that train seems too crazy for me. I'm gonna try another one.
Subway Train (Sammy Subway)
You're looking to go uptown? Downtown? Midtown? Crosstown?
Host (Adam Tex Davis)
Downtown's good.
Subway Train (Sammy Subway)
Okay, follow me. I'll take yas where you want to go?
Host (Adam Tex Davis)
Down these stairs?
Subway Train (Sammy Subway)
Yep, there's a whole world underground. Here we are. Hey, let the passengers off first.
Host (Adam Tex Davis)
Oops, sorry.
Subway Train (Sammy Subway)
Now get in. Stay and clear the closing doors. Please welcome. The name's Sammy Subway.
Host (Adam Tex Davis)
Hey, Sammy, you're my third talking train today.
Subway Train (Sammy Subway)
What do you want, a cookie?
Host (Adam Tex Davis)
According to Diesel, Dottie, you and her rule the rails these days.
Subway Train (Sammy Subway)
That's right. A subway's an electric train. And people in cities ride them all the time. We use electric motors like diesel trains, but unlike them, we don't get our power from fuel or from burning stuff. Instead, remote power stations give us juice, AKA electricity through overhead cables or an extra rail known as the third rail. Don't get too close to it though, or else, pow. It'll zap you. Bada bing, bada boom, bing bong. Compared to diesel and steam trains, electric ones are faster, quieter, and more reliable. And cleaner.
Host (Adam Tex Davis)
Why is the floor all sticky?
Subway Train (Sammy Subway)
I can't help but if people spill stuff.
Host (Adam Tex Davis)
What'd they say?
Subway Train (Sammy Subway)
Or that nobody fixes my PA system. This is just trains of the future.
Host (Adam Tex Davis)
You mean there's something beyond electric?
Subway Train (Sammy Subway)
Oh, yeah. U.S. electric trains may be your subways, commuter rails, and high speed bullet trains like the ones in Japan that can go 185 miles per hour. But if you want a train that really flies, see my friend across the platform. See ya.
Host (Adam Tex Davis)
Hmm. A train that flies. Hello.
Maglev Train (Maggie)

Maglev Train (Maggie)
I'm Maggie. A maglev high speed train. I don't have any wheels.
Host (Adam Tex Davis)
No wheels? Then how do you move? Is it with A, rockets, B, propellers, or C magnets? Oh, the answer is C. Magnets.
Maglev Train (Maggie)
Correct. Maglev is short for magnetic levitation. Using magnet forces. I actually float above the tracks, eliminating friction that slows trains down.
Host (Adam Tex Davis)
In other words, maglev trains can truly fly at speeds that were once unthinkable.
Maglev Train (Maggie)
Where would you like to go?
Host (Adam Tex Davis)
I don't know. Paris, London, Moscow, Brazil, South Africa.
Maglev Train (Maggie)
How about Shanghai, China?
Host (Adam Tex Davis)
Oh, I've always wanted to go to Australia.
Maglev Train (Maggie)
Shanghai it is. Thanks for riding the Shanghai high speed maglev train serving Shanghai.
Host (Adam Tex Davis)
Ah, yes. There are only six maglev train systems in the world, all in Asia. And only the Shanghai one is high speed.
Maglev Train (Maggie)
I can go 286 miles or 460 kilometers per hour. China is building track for a new train that can go 373 miles or 600 kilometers per hour.
Subway Train (Sammy Subway)
Wow.
Host (Adam Tex Davis)
That's over twice as fast as a bullet train. At that speed, you'd be able to cross the United States in less than eight hours.
Subway Train (Sammy Subway)
Whoa.
Host (Adam Tex Davis)
Sadly, there are no maglev trains in the USA yet. The problem with these trains is that they require entirely new tracks. So everything would need to be built from scratch.
Maglev Train (Maggie)
Yes, but maglevs make little noise and don't require much maintenance. We also create little or no air pollution. We're helping the planet.
Host (Adam Tex Davis)
I'll say. Which is why China is expanding its network with plans for more high speed maglev trains in other countries like Japan and Germany. Maybe someday you'll be able to take one of those home.
Maglev Train (Maggie)
Welcome to Shanghai.
