wunder beta🚂 All About Trains
Meet the mighty machines that ride the rails, from puffing steam engines to the fastest trains on Earth.
What you’ll learn
- How Steam Trains WorkedUnderstand that steam locomotives used a fire to boil water into steam, which pushed the wheels.Steam trains had a fire inside that heated water until it turned into steam. The steam pushed a sliding piece in a cylinder, and metal rods carried that push to the wheels. A fireman shovelled coal to keep the fire hot. Steam trains were powerful but needed lots of coal and water, so newer trains were later built.
- Diesel and Electric TrainsLearn how diesel trains use an engine and electric trains use overhead wires or a rail.Modern trains skip the fire. Diesel trains have a big engine that often makes electricity to turn the wheels, and they can go almost anywhere. Electric trains carry no fuel; they get electricity from overhead wires or a special rail. Electric trains are fast, quiet, and clean, and many city trains and subways are electric.
- Freight and Passenger TrainsTell the difference between passenger trains that carry people and freight trains that carry cargo.Passenger trains carry people, with seats, windows, and sometimes beds on sleeper trains. Freight trains carry cargo like food, cars, coal, and huge boxes, and can have more than a hundred cars. One freight train can carry as much as hundreds of trucks, making trains a smart way to move heavy things across a country.
- The Fastest Trains and Who Drives ThemDiscover the fastest real trains and how signals, tracks, and a driver keep trains safe.The fastest trains include Japan's Shinkansen and France's TGV at about 320 kilometres per hour, and maglev trains that float on magnets and reach around 430 kilometres per hour. Trains run on two rails, guided by switches where tracks meet, and coloured signals tell the driver when to stop or go. A real driver at the front controls the train and follows the track.
Questions this course answers
What did a steam train use to make its power?
A fire heated water until it turned into steam, and the steam pushed the parts that turned the wheels.
What was the fireman's job on a steam train?
The fireman shovelled coal all day to keep the fire hot so the water kept making steam.
Where does an electric train get its power?
Electric trains carry no fuel; they get electricity from overhead wires or a special extra rail to spin their wheels.
What is a clever surprise about how a diesel train works?
A diesel train's engine usually makes electricity, and that electricity is what actually turns the wheels.
What does a freight train carry?
Freight trains carry cargo, which means goods like food, cars, coal, and huge boxes, sometimes in over a hundred cars.
What might you find on a sleeper train?
Sleeper trains have tiny beds so you can fall asleep in one city and wake up in another.
