How far away can you hear a train on tracks?
How far away can you hear a train on tracks? If I am up to an education center that I help out at I can hear trains down in the valley about 800 ft below all the time. This is about 6 miles. On a cold clear night I can hear trains at home. This is about 8 miles away.
What does it mean if you hear a train whistle?
Today, the only whistle signals you're likely to hear regularly are the grade-crossing warning (which is also often used to warn employees or others on the tracks); two (or three) shorts to indicate the engineer has received a signal to start the train forward (or backward); and one long blast when a train is ...

Strictly hissing is likely brakes and would be close to a train that's starting. But If you mean the high-pitched singing sound you get well before a moving train arrives, that is the result of transmission of sound waves along the track.
Why do trains shake my house?
The length, height, width, and composition of the building and its distance from the tracks, determines its natural oscillating frequency and the train's length and speed must create an oscillation that closely matches the building's frequency (or its harmonics), so that the small train vibrations get amplified to ...
Why do trains honk when going through towns?
Why do trains sound their horn? Federal law requires the train crew when approaching a road crossing to sound the horn at all public crossings for the protection and safety of motorists and pedestrians regardless of whether crossings with gates and lights are present.

Anyway, don't blame the engineer: They're required to blow that horn. The regulation in question is called the Final Rule on the Use of Locomotive Horns—a name that strongly implies they've had just about enough of your bitching—and it requires four blasts 15 to 20 seconds before every crossing.
Will a train stop if it sees you?
By the time a train operator sees you, it is too late to stop the train in time. An oncoming train is moving faster and is closer to you than it appears. Similar to an airplane traveling at 150 mph that appears to float onto the runway, it's hard to determine a train's speed and distance from you.
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.
Why can I hear trains so far away?
When air warms with altitude a temperature inversion exists. 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.
Are trains loud to live next to?
Noise pollution and vibrations are some of the biggest concerns, particularly for people who live within one-third of a mile of railroads or railyards, says Natalia Caldeira Loss Vincens, an expert in public health at the University of Gothenburg in Sweden.
Why do trains honk in residential areas?
Train horns may be sounded in emergency situaons or to comply with other railroad or FRA rules even within a quiet zone. Quiet zone regulaons also do not eliminate the use of locomove bells at crossings.
