The K5LA is a five-chime airhorn that was invented by the Nathan Company in the 1990s for Amtrak. Amtrak wanted a horn that would give its trains a more cheerful sound than the P5 did. This recording came from a SoundTraxx Tsunami2 sample. This file fits any EMD F40PH.
Version 2: Replaced bell recording with a better one, lowered the build number to ensure backwards-compatability.
