Nathan AirChime K3LA 540, Train Horn Kit

The Nathan K3 AirChime is a real diesel locomotive horn. Designed in the 1950s, this is the definitive loud air blast that you've heard as the train barrels down the track. This horn is just about indestructible; die cast out of solid aluminum and powered by heavy duty stainless steel internals. This kit contains everything you need to install it on any vehicle. An extremely loud train horn that is still in use on real locomotive engines, a five gallon air reservoir to supply lots of air, a Viair 400C compressor pushing 2.54CFM to ensure fast fill rates, and all fittings and accessories needed to ensure stable and long term use!
