The Wichita Train Whistle Sings was created in 1968.

I think its the quad city djs or the 69boyz

Santa Catalina sings about 26 miles.

If you miss the train I'm on...you'll hear the whistle blow a hundred miles

Yes. 'Train whistle' is a compound noun, which means that both 'train' and 'whistle' are nouns individually but here they work together. The word 'train' is applied to 'whistle' in the place of an adjective, that is, a word that describes the type of whistle.

But have you ever heard a wolf whistle?

Many compound nouns eventually run together, like handbook or cupboard, and maybe one day, wolfwhistle.
