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.
To avoid the immediate destruction from train cars derailing and striking buildings near the tracks, you would want to be at least 500–1,000 feet away from the nearest track. In the case of chemical spills, hazardous gas releases or fires and explosions, you need to be almost ten miles away from the tracks.
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.
That's because the noise a train makes is mainly projected to either side. When trains are moving directly towards you they are barely audible–until it's too late.” He adds: “It's surprisingly easy to overload the brain to the point where it can't triangulate where sound is coming from.”
What happens if you stand too close to a train? Air between person and the train moves with high velocity due to dragging effect and the air behind person is approximately still.
The engines in diesel locomotives and DMUs produce significant amounts of noise. Newer locomotives have become much quieter in recent years due to noise regulations being implemented by countries and regions.
Many homes near train tracks will shake when the train passes due to the train design, length, weight, cargo, and speed. You can use thick padding and carpet floors. Make sure all doors and windows are insulated.
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 ...
Because if there is a front-end collision or a rear-end collision, the damages will be greater at those locations. The middle of the train is by far the safest for persons.
When the rule established the requirement for routine sounding of the locomotive horn, a procedure was also established whereby localities that could meet certain safety requirements might designate as a “quiet zone” a segment of a rail line with one or more consecutive public highway-rail grade crossings.
Guests are asked to limit conversation and speak in subdued tones. Phone calls are not allowed and all portable electronic devices must be muted or used with headphones (passengers using headphones must keep the volume low enough so that the audio cannot be heard by other passengers).
