Nathan Airchime K5LLA-R1L
This is an airhorn used on North American Locomotives. These horns are mostly seen on BNSF, UP, NS, CSX, and CP. Most are used on new EMD SD70ACe and SD70M-2 locomotives. As you may realize, I have already flipped the 1L bell for the correct bell configuration. This is a newer 3rd generation K5LLA as seen/heard on EMD’s newer fleet locomotives.
