Our lowest priced complete train horn kit, the Black Outlaw 228, is not a train horn kit to be underestimated. We built this kit for the value shopper; that said, we didn’t over look any of the features that make our horn kits the best on the market. This horn kit features a fast filling 150 PSI air system, a loud Outlaw train horn, and all the fitting and wiring accessories you’ll need.
