Digital Command Control, or DCC, is a set of regulations defined as a Standards and Recommended Practices that the National Model Railroad Association, or NMRA, recommends. Systems using the DCC setup cannot be mingled with other types of systems. They’re easily identifiable by the DCC logo on the packaging or on the product. You can visit the DCC website to learn the exact standards and recommendations set forth and to better understand the importance of this product in the locomotive industry.
The dcc command station is sold with the station and a power supply. Sometimes it is made as a single unit; other times it is made into separate pieces. It may be handheld or a console type divide. The locomotive engine must have a decoder installed for the DCC to work. The decoder is a DCC receiver that must be placed on the locomotive layout and not inside. The DCC sends a packet of information over the rails that contains the data generated by the command station. Since each decoder has a unique address, it is easy for the command station to determine which locomotive has sent the information.
Decoders tell the locomotive a variety of information, such as to increase or decrease the speed, blow the horn, change directions, or other features available with the decoder. Some operators opt to use two decoders or more to ensure they get the right messages to the locomotive. There are a plethora of advantages offered when the DCC is used. This includes independent operation on more than one track, trains can travel at different speeds or in different directions, or they can run like the real thing! The secret is choosing the very best DCC that you can find in your price range, so take the time to choose wisely.
