Found my old train whistle from childhood in the attic today, I decided to toy with it a bit, and I finally discovered how it works (having lost track of it when I first got into music theory). Four chambers, each tuned to a different pitch, creating a chord when blown into.
In this case? C-Eb-Gb-Bb, a C half-diminished-seventh chord.
And I figured out that both in toy form and in real life, they’re conditioned to produce a chord, and freight trains in particular often produced dissonant chords, a useful side effect for convincing people who might be on or near the tracks to move the hell out of the way.
