Wolo, the first company to offer ABS plastic train horns to the public has finally solved the problem of wanting a brawny sounding horn without taking up a ton of space: the Express Pro Train Horn. A universal flat rack design makes installation easier than almost any horn system on the market, and allows you to separate each of the three Black trumpets from the mounting base – perfect for trucks and SUVs with limited mounting space.

Your Wolo Express Pro Train Horn includes a rugged Steel mounting base, which is finished in a Black powder coat. This base along with the 4 heavy-duty rubber bushings virtually eliminate road vibrations, even on the bumpiest of off-road excursions. Your included compressor features a heavy-duty 12V motor which has been factory balanced for absolute precision. A pressure switch, manual water drain, pressure gauge, and pressure relief valve are all fully integrated.

Each kit contains everything you’ll need for a complete and professional installation. That includes an on-board air-system capable of producing the high pressure needed to blast out a blaring sound. An extended length Stainless Steel high pressure hose connects your compressor to the included 2.5 gallon storage tank. Mounting hardware, high quality brass fittings, and 10' of flexible high-pressure hose are also included. Backed by a 3-Month Warranty.
