The trouble with trying to
make trains go faster
By Katia Moskvitch

As technology advances, transport gets
ever faster, and trains are no exception. But
with great speed come great drawbacks.
Katia Moskvitch reports on the pitfalls facing
train designers trying to reach even greater
speed on rails.
Since George Stephenson’s Rocket,
designers have been trying to make trains go
faster and faster. Despite all the innovations,
particularly in the last 50 years it’s still a
dream that all cities around the world could
be connected by high-speed trains that
complete journeys in a flash, allowing you
to arrive at your destination relaxed and
untroubled. Why is this the case?
Going fast on rails brings its own special
set of problems. Human bodies are simply not
built for rapid acceleration, we experience
certain low frequency motions that create
discomfort – a feeling of “motion sickness”.
We also experience rapid acceleration, for
example, each time we take off and land in
a plane.
Then there is the logistics of trying to send
a train faster along a track. Going fast means
pushing air out of the way, which also requires
a lot of power. A train travelling at 300mph
(480km/h) uses roughly 27 times more power
than one travelling at 100mph (160km/h). And
at ground level the air is a lot denser than it is
at 35,000ft (10,600m) where airliners regularly
cruise. That means more resistance, and
therefore more vibrations.
If trains could travel just in straight lines
and without any dips, then high speeds
would not be a big issue. It’s the bends and
the ups and downs that create a problem,
especially in Europe, with its many rivers
and mountains and old train lines following
long-travelled routes.

Questions:
1)The main idea of the text is:
a) To advertise the launch of the railway lines
throughout Europe in spite of the hurdles
to deliver them.
b) To show that the human body is unable to
put up with rapid acceleration.
c) To expose the glitches that hinder us from
traveling faster by train.
d) To point that there are also technical
predicaments such as going up and down
slopes when it comes to moving trains at a
faster pace.
e) To praise the strides technology has made
so far regarding bullet trains.
2) Which title fits better in the text:
A) The evolution of technology.
B)The trouble with trying to make trains go faster
C) Trains are cool
D)Traveling on flash light
E)None of the other alternatives
