Wolo 838 Cannon Ball Express® 24-Volt 152 Decibels 307/347/440 Hz - Train Horns

The Wolo Model 838 Cannon Ball Express is an ultra-powerful train horn designed to give any 24-volt truck a true train horn sound. Constructed entirely of metal, it features three triple chrome-plated trumpets mounted on a durable painted steel base. This horn is engineered for those who demand a loud and commanding presence on the road.

The Cannon Ball Express requires an on-board air system for operation, with Wolo models 840, 858, and 860 recommended for optimal performance. The kit includes all necessary mounting hardware, a 10-foot length of 1/4-inch nylon high-pressure hose, and a heavy-duty 24-volt electric solenoid valve, ensuring a complete and hassle-free installation. Its robust construction and high decibel output make it a reliable choice for heavy-duty vehicles.
