76. How a High-Speed Train Works
A high-speed train is a modern and efficient
to travel long distances quickly. But how is
powered and operated?
Unlike old trains that use
engines, most high-speed trains run on electricity. They
this power from cables above the tracks, called
lines. A device on top of the train,
as a pantograph, touches these lines and transfers
electricity to the train's electric motors. These motors
turn the wheels, allowing the train to move
smoothly and quietly at very high speeds.
Operating
high-speed train is a complex job that relies
advanced technology. A driver, or engineer, sits in
cab at the front, but they are helped
many computers. An advanced system controls the train's
and keeps a safe distance from other trains
the track. The driver monitors the signals and
track ahead on a screen.
Furthermore, the tracks
specially designed for high speeds. They are very
and have gentle curves to provide a safe
comfortable ride for passengers.
In short, a high-speed
is a powerful machine that uses electricity and
technology. It combines a human driver with advanced
to transport people safely and efficiently at incredible
.
