Used to get a steam engine come up the valley here on it's way up to Syracuse for running tours up into the Adirondacks. I agree with William, I'll that a steam whistle over a diesel horn any day. A truly beautiful sound.
The trail owner died a few years ago and the line has been abandoned. Now, the closest I get to hearing anything like it is exhaust whistles on some of my customer's cars.
These pix are of a four reed (chime) type that were more common. There are bigger units, but they are rare because they need a lot of exhaust volume from something with a big motor, like a big Locomobile, or Stutz, to work. Not as loud as a steam train whistle, but the bigger ones can still be loud enough to have people very perplexed about just what is coming around that bend in the road.
Or, have you jump a foot in the air if they let loose with one of those big whistles while your near the car !
I sure do miss that steam engine though. That's one coal stove I'd love to shovel coal for just for a ride !!!
