Who actually picks the tone and decible level of the horns used? The Gov't? the RR"s themselves?, The Manufacturers?
Back in the stone age, the whistle of a steam engine had an almost enchanting affect.
The first generation diesels (F-7's etc) with their "buzzer" sounding horns were not overbearing, either.
Even the second generation diesels, with their 'muted trombone' sound was not as piercing as todays modern horns.
Seems as though a lot of effort has gone into finding an intonation
that is as irritating as possible, probably to make them more
noticeable, but by same token more contemptible.
Just curious if the Gov't specifies that rigidly, or if the various RR's have their own standards.
One of the locals here on the NS has a unit with not all of it's chimes working, the shrill, highpitched end is missing.
And while it is slightly off key as a result, it actually is a more
pleasant horn to have around, sounds almost like when those old
blues trumpeters would hold a bowl over their horns for that hollow
sound. Easy on the ears.
I laugh to myself everytime I hear them go by.
