Roughness and irregularities on the wheel and rail surfaces are a source of noise and vibration. Rail joints and squats on the rail cause a familiar clickety-clack sound as train wheels roll over them.

At night, the air near the ground can have a different temperature than air only a few hundred feet above1. This affects the transmission of sound waves. There is usually less ambient noise after dark, so the distant train sounds louder.
If you hear, two small horns, it means the motorman is asking the guard to direct the railway signal to start the train. In case you hear three smaller horns, it suggests that the motorman has lost control over the train. This also acts as a signal to pull the vacuum break immediately. This signal is rarely heard.
Rail squeal is a screeching train-track friction sound, commonly occurring on sharp curves. Squeal is presumably caused by the lateral sticking and slipping of the wheels across top of the railroad track. This results in vibrations in the wheel that increase until a stable amplitude is reached.
Train Horn RequirementsUnder the Train Horn Rule (49 CFR Part 222, issued on August 17, 2006), locomotive engineers must begin to sound train horns at least 15 seconds, and no more than 20 seconds, in advance of all public grade crossings.
One short whistle means STOP. One long whistle (three to 10 seconds) means the train is approaching a station. Two short whistles mean that the engineer acknowledges that he or she heard or saw a signal that affects movement.
Trains also use horns, whistles, bells, and other noise-making devices for both communications and warnings. 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.
In one study conducted at the BNSF Railway Hobart Railyard in Los Angeles, the California Environmental Protection Agency estimated that residents living near a railyard experienced a higher risk of carcinogen exposure.
any train that arrives early into a station to receive passengers can depart early if it is notated to reflect as such in the timetable. What are the new Amtrak superliner rail cars?
This location may be surprising, but loud music, car horns and sirens can hurt your ears, especially if you have your windows open. Even passing trains can affect your hearing with their horn reaching 145 to 175 decibels.
How many decibels is a real train horn? Car horns and train horns are measured differently because of their size, a train horn is much bigger and can create more noise. Train horns are typically between 110-140 decibels in sound level! They may sound very similar but completely different levels.
It depends on what you're eating. Discrete, low key snacking is fine as long as you clean up after yourself and leave no trace that your food was ever there. But eating something messy and smelly is probably a bit much. No not rude at all, but be aware of your travel companions and if your food smells bad to them.
