Train Whistles

I don't know whether this should be classified as a musical instrument or not.
I suppose it is as musical as a "slapstick." No, I don't mean a style of physical humor.
A slapstick is a percussion instrument that imitates the sound of a whip being cracked.

This wooden device is designed to imitate the sound of the whistle on an actual train.
It has a pretty cool sound to it, but of course you can't play any tunes on it.
Notice it has the stamped image of a train on the side, as a clue to what it does.
You simply blow into the round hole at the end, and the other openings do the rest.

Duluth Trading Company specializes in clothing, not musical instruments or noisemakers.
However, for a fee, you can have your own logo printed on train whistles to use as advertisements.

I bought this one in the great town of Skagway, Alaska, population 1,000.
It's one of the few places in southeast Alaska you can drive to in a car.
But it's more famous for its rail line, making this a fitting souvenir.
This whistle doesn't sound very good, partly because it has only two "lips."

The above four-note train whistles play the following notes, lowest to highest:
B-flat / C / E-flat / G
So, for you music theory students, a third-inversion C minor seventh chord.
In guitar chords, that would be designated "Cm/Bb".
But then, it's hard to make a guitar sound like a train.
I tried it.
