THE UNDISPUTED KING OF TRAIN HORNS

The most common question we get asked is, “What are your loudest horns?”  Well, here they are! The same horn used on most American locomotives for decades, the Nathan AirChime K5LA train horn. While there are many kinds of train horns, the Nathan AirChime K5LA is the golden standard that other train horns attempt to duplicate. With its massive size and intimidating tone, the Nathan AirChime K5LA proves that if you want a train horn, there really is no substitution for the Godfather of Train Horns. With its lower profile straight manifold, the LA style is the best choice for installs where you are limited on space vertically, but have plenty of room horizontally. 

As America's most popular train horn since the 1980s, the AirChime K5LA train horn is best known for its unusually upbeat and thunderous tone. Sought after for its looks as well as its sound, the Nathan AirChime K5LA is constructed with five large die-cast aluminum bells with stainless steel diaphragms, mounted on their famous low profile bracket. The AirChime K5LA train horn is built tough enough to withstand years of wear and tear from rain, snow, and sun for years. Put through hours of machine time until the tone is perfected, you don’t get higher quality than these horns. In a sea of pretenders, make sure you get the real deal.
