Steve when you fold that up does it become a Swan?
I don't know. My brain freezes every time I look at it. No wonder acoustic engineers have an odd look in their eyes. :P

Why does this whistle have a valve to let off air?? Any one know?
because it also served as an emergency air dump
I've heard from some old heads from my days at the railroad that a good conductor or brakeman could actually use the whistle to bleed off 2-3 psi of air from the train line, thus causing the attentive engineer to realize what was going one. I was also told that a minimum set (7 psi reduction in trainline) could be done with the caboose whistle. How many times did the conductor dump the trainline before he realized and learned how much he could bleed off? Who knows... :P

Hello Again
I finally made a video featuring my caboose whistle. I don’t know why it sounds so “airy”? on the video. In person it does have a hiss to it but it is alot louder and clearer.
Here is the link.
