TABLE OF CONTENTS CHAPTER EARLY TRAINS A loud horn blows in the
distance. Crossing gates
lower. A train roars by! Do you ever wonder what makes
a train move? How does it speed
along the tracks? Trains are
amazing machines. How do
they work? Lets find out! Steam pulled early
trains.

Water and steam powered
them. How? Coal was burned
in a firebox. This heated tubes
in the boiler. Water around the
tubes boiled. This created steam.
The steam built up .

rods Pressure from the steam pushed
pistons.

Pistons connected to rods.
The pistons moved the rods back
and forth. The rods attached
to the wheels. They turned the
wheels, moving the train forward.

TAKE A LOOK! All parts of a steam locomotive worked together. WATER COAL SMOKESTACK FIREBOX DRIVING
WHEELS RODS WATER TUBES CHAPTER DIESEL AND
ELECTRIC TRAINS In the 1940s, diesel locomotives
became popular. They have
.
This means is burned inside
these engines.

This creates .

The engine spins an
to produce electricity. Electricity
runs motors on the trains .
This turns the wheels. The largest kind of diesel
locomotive was the Centennial.
They were built between 1969
and 1971. Two diesel engines
made them very powerful. DID YOU KNOW? Each Centennial was feet
(30 meters) long.

They weighed
tons (245 tonnes)!

Not all trains have engines.
Electric locomotives run on
electricity. They get it from
a third track. Or overhead
wires power them. How do trains stop?
Air brakes. Each train
car has an air tank.
Pressurized air from
the tanks pushes
brake pads against
the wheels. This
stops the moving wheels.

DID YOU KNOW? Trains also have manual hand
brakes. They can be used if
the air brakes lose pressure.

overhead wire CHAPTER MAGLEV AND
HYDRAIL TRAINS There are many kinds of trains. Maglevs
are high-speed trains. Maglev is short for
magnetic . They float about five inches
(13 centimeters) above a track
called a guideway. They float about five inches
(13 centimeters) above a track
called a guideway.

How? Magnets.

There are magnets on the bottom of
the train. They are also in the guideway.
Magnets with like poles on the train and
in the track each other. This keeps
the train floating. HOW DOES IT WORK? Magnets also maglevs. Like poles are two north or
two south poles.

They repel and push against each other.
Opposite poles attract. Both help move the train forward. Like poles repel
and PUSH the
train forward. Opposite poles
attract and PULL
the train forward.
