Union Pacific K5LLA Nathan Airchime Real Train Horn!

Ex Union Pacific K5LLA. This locomotive horn came off a retired SD70 Union Pacific train. By far the loudest K5LLA Iv had in the collection. This horn is running with the 1L reversed and gives it a very unique sound! As you can see in the video the UP grey paint has some very interesting wear. The Nathan Airchime logo on the horn is even wore down in several places. K5LLAs have bells 1L,1,2,3a,4a giving it a deeper more demanding tone than your standard K5LA. #unionpacific #unionpacificrailroad #k5lla
