There is less traffic on the tracks during the night, which allows for smoother and faster train travel. Nighttime is typically a less busy time for maintenance and repairs on the tracks, which can also contribute to faster train speeds.

The reason for the different horn sequences are for other employees to know why the horn is being sounded, three short blasts, means the train is backing up, two long blasts means the train is going ahead. One long blast for stopped with the air brakes applied.
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.
So, as you can see from the name, all this honking business is pretty strict and obliges trains to make four blasts approximately 20 seconds before they reach a crossing. But that's not all! Trains whistles and horns are an effective method of communication!
Earplugs: Wearing earplugs can combat the train noise and help you sleep through the night. White noise: A white noise machine or app will provide a constant low-level background noise that can help you sleep through occasional train whistles.
Faster inter-city trains: 1920–1941Rail transportation was not high-speed by modern standards but inter-city travel often averaged speeds between 40 and 65 miles per hour (64 and 105 km/h).
Under 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.
Two short whistles mean that the engineer acknowledges that he or she heard or saw a signal that affects movement. Three short ones mean that the engineer intends to make a reverse movement. Two long, one short and one long mean trains are approaching a highway or street crossing. And the list goes on.
Looking at traffic fatalities per mile traveled in the U.S., analyst Todd Litman found that riding commuter or intercity rail is about 20 times safer than driving; riding metro or light rail is about 30 times safer; and riding the bus is about 60 times safer.
The middle of the train is by far the safest for persons. The National Transportation Safety Board does not release comprehensive data on where victims were sitting during fatal train accidents, though some details are available in individual investigative reports.
Walking on or beside railroad tracks is illegal. The only safe place to cross tracks is at designated public crossings with a crossbuck, flashing red lights or a gate. Crossing anywhere else is illegal.
What is the significance of a train engine sounding a Morse code Q as they approach a crossing? According to railsafetraining dot com, the signal dates back to when the Queen of England traveled by ship. The Captain would blow Morse for “Q” to tell other ships to move aside for Her Majesty.
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.
Most likely, it's just a coincidence. Before radio communication, locomotive engineers used a dozen or so signals to communicate their intentions. With so many signals, all using short and long horn sounds, nearly all of them match up with some letters in Morse code.
