DCC Decoders

DCC Decoders 

Take your model railroad layout to the next level with DCC decoders from Midwest Model Railroad. These devices translate commands from DCC (digital command control) controllers and throttles into special effects in your trains and landscape. While many manufacturers make locomotives with built-in decoders, you can also install them yourself for deeper customization of bells and whistles. You can also put decoders around your layout to create effects like building lights turning on or off, activating traffic lights, and raising or lowering crossing levers. We even have Bluetooth-enabled decoders for high-tech layouts. Midwest Model Railroad has both mobile/multifunction DCC decoders and accessory decoders for layout animations. Contact us if you have any questions.
