Update 6: The First Train Horn has arrived!
I received the first of seven Nathan Air Chime train horns !
The Nathan Air Chime company, the oldest and most respected of all train horn companies has offered me a loan of seven horns for the Distance Music project.
This K1L horn is made of thick cast and machined aluminum: very rugged! It has a 1/2in NPT main inlet port on the bottom of the manifold. This horn is the largest – a C4 261Hz. At 100 psi and 50 cubic feet per minute flow, this horn will produce a sound louder than a jet engine. Extremely efficient – EXTREMELY DANGEROUS.
