Hello Everyone

What is the difference between AF's  Electronic Air-Chime Horn, Air-Chime whistle,  Nathan Air-Chime Whistle?

Thanks

I beleive that these names are all pretty much descriptive of the same device, which is a buzzer tuned to "simulate" an air horn.  All operate on the same principle; an oscillator in the control device sends a 600 cycle signal through the track which is picked up by a speaker in the engine tender or diesel locomotive body.  The only differences revolve around the control mechanism by which the signal is generated.  The earliest models built in 1950 operated on 110 volts and employed an electronic vacume tube.  The later models used a mechanical vibrator instead and ran on 15 volt accessory power.  The parts inside the locomotives were pretty much the same with both controllers.

Most of the latr whistles/horns used a push button control producing a single sound, mid 50's steam whistles had a sliding control that produced a variable sound, which was better sounding.

Thanks, now I understand, did not realize the early ones needed 110volts
