Wolo Philly Express Pro Truck Train Horn delivers the powerful sound of a train air horn with a heavy-duty high-pressure air system. If you want people to hear you before they see you, this is the truck train horn to look into.

The four trumpets and mounting base are constructed of all metal, triple chrome plated Built into the horn's base is a heavy-duty, chrome plated 12/24-volt electric solenoid valve. The high-pressure air system consists of a heavy-duty compact compressor and a 2.5-liter steel air storage tank. The air system has a built-in pressure switch that will maintain 110 psi of air pressure in the storage tank. All moving parts of the compressor are manufactured to strict standards. The compressor's motor is carefully balanced, and the mounting bracket has heavy rubber bushings which virtually eliminates vibration. Air hose fittings are made of quality brass to ensure a leak free installation. Comes complete with all necessary mounting hardware, 10 ft. of 1/4.in. O.D. nylon high-pressure hose, and 20 ft. coiled filler hose with quality brass fittings.

Designed smaller to fit into engine compartments that are unable to accommodate a full size train horn. If you're in the market for a smaller train horn for your truck, but still want to make some serious noise, the Wolo Philly Express Pro truck train horn is the system for you.
