What is the frequency of the rail line?
What is the frequency of the rail line? Railway electrification systems using alternating current (AC) at 25 kilovolts (kV) are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60 Hz), which simplifies traction substations.
Can you feel vibration on train tracks?
Trains do create vibration, and if you live close enough to the tracks, you can probably feel it when the train goes by. However, there is a very large difference between the point at which a human feels vibration and the point at which vibration can cause damage to even the most fragile structures.
Why can I hear a train from miles away?
Sound travels faster in warm air than it does in cool air. This means the sound of a train horn will bend downward when it passes through an inversion causing sound waves to propagate farther than normal.
