The train whistle, or horn, is an important part of our safety practices. The horn alerts people that a train is approaching a railroad crossing. It can also be used to warn animals or trespassers in our right-of-way along a section of track.

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.
Federal Railroad Administration (FRA) rules require locomotive engineers to sound train horns between 15 and 20 seconds, but no more than a quarter-mile, in advance of all public grade crossings. Train horns must be sounded in a standardized pattern of two long, one short and one long blasts.
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.
By 1938, the Association of American Railroads had adopted the long-long-short-long signal for rail crossings. But whatever the horn pattern, the goal is to warn people well in advance that a train is coming. In 2021, 236 people were killed at highway-rail grade crossings in the US.
motorists often try to beat the train at crossings and if it's a tie you lose. for this reason locomotive engineers are legally. required to blow their horns at crossings at least 15 seconds before they reach a crossing.
Reduced traffic: During the nighttime, there is generally less road traffic and fewer other trains on the tracks. This allows trains to move more efficiently and with fewer delays, as they encounter fewer obstacles and can maintain a consistent speed.
Answer #1: It's a wave of communicating between the train driver and workers on the tracks to acknowledge that the driver has seen them. Answer #2: For safety reasons – to make sure the horn is working before you leave the station.
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.
In a quiet zone, railroads have been directed to cease the routine sounding of their horns when approaching public highway-rail grade crossings. Train horns may still be used in emergency situations or to comply with other Federal regulations or railroad operating rules.
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.
The intensity of sound will vary at night, sometimes louder and sometimes softer. It has to do with the height and strength of a temperature inversion just above the ground. On clear, calm nights, it is cooler at the ground than higher up.
Train whistles are used to communicate with other railroad workers on a train or in the yard. Specific combinations of long and short whistles have specific meanings. They are used to pass instructions, as a safety signal, and to warn of impending movements of a train.
“People assume that trains are loud, but that assumption is based on the fact that when a train's gone past them in a station it's noisy. 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.”
