I'm a big rail fan.
I got to see the Union Pacific 4-8-8-4 "Big Boy" steam locomotive in person a few years ago.
I'm thinking the sound of the steam whistle on that beast would command respect among the unwashed masses.
Got to see a CT in person in Atlanta, GA today.
Yes it is far more impressive in person.
From where the camera was when she hit the button, I think it sounds like my louder Fiamm “ freeway blaster” horns that I use in my cars. I don’t see a problem.
If the horns are 48 volts, you may have limited options to replace them for a while.
