If for no other reason, the horn can alert those folks to get to safety. either to alert people when they enter the tunnel(like MOW, or trespassers) or in some cases, to be friendly at kids(or railfans) at the tunnel entrance.

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.
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.
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.

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.
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.
Passenger cars, or coaches, vary in their internal fittings: In standard-gauge railway cars, seating is usually configured into ranges from three to five seats across the width of the car, with an aisle in between (resulting in arrangements of 2+1, 2+2 or 3+2 seats) or at the side.
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.
Train Horn RequirementsTrain horns must be sounded in a standardized pattern of 2 long, 1 short, and 1 long blasts. The pattern must be repeated or prolonged until the lead locomotive or lead cab car occupies the grade crossing. The rule does not stipulate the durations of long and short blasts.
