1NATHAN K5HA 540

The Nathan AirChime K5HA 540 Train Horn Kit is designed for the loudest and fastest blast. It combines authentic Nathan AirChime K5HA train horns with a fast-filling onboard air system. These die-cast aluminum horns with stainless steel diaphragms are built for durability and have been used in US Locomotives since the 1970s. The K5HA horns feature a T-shaped manifold, distinguishing them from the K5LA. The kit includes the HornAir 540 Onboard Air System, featuring a Viair 400C Air Compressor, which provides 5 seconds of continuous blast time from its 5-gallon tank and can recharge from 110 to 150 PSI in about 90 seconds. All necessary hardware and instructions are included.
