Refurbished AirChime K5 Train Horn

These beastly sets of horns are the pride of the railroad. Almost every freight train in the USA boasts one on top of its locomotive. The sound is iconic; if you’ve heard a train barelling down its tracks blowing its horn along the way, then you’ve heard these in action.

Now these horns in question are the exact same, but have been used and returned by another horn fanatic such as yourself. They’re still insanely loud and one of the best deals on our website!

All used Nathan horns have been returned to us by our customers and have been inspected. They are bead blasted if they are excessively dirty and tested at 120 PSI. THESE ARE NOT PERFECT HORNS. We make sure they are in working condition, but any wear and tear from use will still be present.
