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.
