For the past 60 years, the air horn has virtually replaced the steam whistle on all locomotives. Things may be about to change! This is the first test of my new K5LA chime whistle on a locomotive. I designed it to duplicate the frequencies of a popul...ar air horn on air.

It uses no more CFM than any steam whistle of the same dimensions but uses a mere 35 PSI to achieve full output. This gives a severalfold increase in efficiency and when regulated, greatly increases the full power blowing time on a given size tank. It was built by Mike Daugherty of MD Whistles who arranged this test.
