Cell phones,
tablets
and headphones
are great conveniences
but don’t let technology distract you
when you’re near train tracks
or waiting on a platform
Modern trains are
Quick
&
Quiet
If you’re listening to loud music
you might not hear the train
Ever heard of a decibel?
It measures how loud sounds are
on a scale from 0 to 130
How loud do you think a Train is?
  1. 78 dB
  2. 93 dB
  3. 125 dB
Force
is the strength
or power
exerted upon
an object
Force is measured by calculating an object’s weight multiplied by how fast it travels
Mass x Acceleration
=
Force
Silverliner V
Mass

730,000 lbs.
Acceleration

Think of it this way
How much force would a superhero need to exert to stop a 5–car train weighing 730,000 pounds, travelling 70mph?
  1. None – we’re talking about a superhero
  2. 351,727 Newtons or 79,402 lbs of force
  3. 37,240,000 Newtons or 8,371,924 lbs of force
Did you know
in some areas
SEPTA & Amtrak trains go up to
70
miles per hour
(112.7 kilometers per hour)
Travelling at 70 mph, how long do you think it would it take a train to stop
  1. 300 feet
  2. 1,500 feet
  3. Trains are able to stop instantly
Facts to remember:
Sound:
A train can be quieter than your car,
a vacuum, and even your music
Force:
A 5-car train travelling at 70 mph (112 kph)
produces 353,200 Newtons of force.
That’s equivalent to 79,403 pounds of force
Speed:
At maximum speed (70 mph/112 kph),
a train can take up to 1,500 feet to stop
that’s five football fields
Remember
STOP
when you see and hear
activated flashers bells and gates
the train has the right–of–way
Never assume the train
is going to slow down or stop
because there is a rail station
next to the crossing
Don’t attempt to beat the train
to the crossing
The train always wins
