Description

This kit features the Nathan AirChime K5HA train horns, known for their loudness and authenticity, made from die-cast aluminum and stainless steel diaphragms. The K5HA horns are sought after for their T-shaped manifold. The kit includes the HornAir 540 Onboard Air System with a 5-gallon tank and a Viair 400C Air Compressor, which recharges from 110 to 150 PSI in about 1.5 minutes, providing 5 seconds of continuous blast time. All necessary hardware and instructions are included.
