Sporting a Viair 400C Air Compressor, our Nathan AirChime K5 540 Train Horn Kit is the fastest filling system we have to date, able to refill from 110-145 PSI in only 1 minute and 40 seconds!

OUTSTANDING

Had a smaller horn setup which pales compared to this setup. Old compressor corroded and developed a leak that could not be fixed. Good excuse to get this outstanding kit. Added a few extra parts like a remote valve switch for the tank drain and a few extra elbows, but all in all a very good complete kit. Mounted the tank and compressor in a tool box in the bed for wx protection. It definitely gets peoples attention, especially distracted or rude drivers. Have had a few trains return a blast or two, LOL.
