Train Horn FAQ

Yes. The kit includes BS135 Battleship horn, air tank, 1NM compressor, wireless remote, hoses and fittings, wiring, and all installation hardware. This installation features upgrades with a 5-gallon tank and dual 1NM compressors for enhanced performance.

With the 5-gallon tank, you get approximately 10-12 seconds of continuous honk time. Dual 1NM compressors provide lightning-fast recovery between blasts, ensuring quick refill times for frequent use.

The system operates at 150 PSI maximum working pressure and restarts at 110 PSI. The dual 1NM compressors feature 100% duty cycle at 100 PSI and 1.75 CFM flow rate at 0 PSI each, providing rapid recovery times with the upgraded configuration.

The BS135 Battleship horn is constructed from cast aluminum, providing excellent durability and weather resistance. The horn measures 42" length, 20" width, and 20" height, weighing 45 pounds, and delivers a deep, powerful tone that demands respect.

Dual 1NM compressors provide faster recovery times and higher reliability compared to a single compressor. With both compressors working together, the system refills the 5-gallon tank much quicker, allowing for more frequent blasts without waiting for long refill periods.
