***** 5 Chime Horn?

Hey guys, I stumbled across this video on Youtube, and was curious about the 2nd horn. Apparently it is a ***** 5 Chime (not sure why the website puts ***** every time I try to say the name of the manufacturer of this horn)? I really love the sound. Are there any railroads currently using this horn?

He custom tuned those horns to sound like a Nathan Airchime. You could buy an actual Nathan Airchime for less money than those. Then you would have yourself an actual trainhorn.

This website censors it because the company that builds those horns designed and built the horns that are now called the Hornblasters Shockers and for some reason, Hornblasters doesn’t want anyone knowing that. It’s a beautiful sounding horn though.
