I used to service the locomotives at a Norfolk Southern yard.
I have been pretty up close and personal with a lot of the horns.
Compared to what these aftermarket companies are passing off as "train horns", the real thing is HUGE.
The air pipe plumbed into them is also HUGE.
I have known them to "POP" the brake-button on a big truck when sounded any more than a short blast.
And YES, they can make the concrete vibrate.
I wish there were a railroad track across the back-side of my property; I love to hear them go rushing through the night.
