What are the NMRAA DCC Standards and RPs?
The NMRA has been working with manufacturers for more than 4 years to develop the next generation of train control. One of the big advantages of this is compatibility across manufacturers. Put another way, some only buy LGB, but if you put a Aristo Craft locomotive on the track it will run as you are not tied to a single manufacturer. DCC offers the same for multi train control systems. The Standards and Recommended practices cover a whole range of features and the various manufacturers have selected the features they feel best meet their product line objectives and products. Thus, if you have a locomotive with the LGB multi-train control decoder inside, it can run on any DCC compatible system. Likewise, if you have a decoder that is DCC compatible it can be operated by the LGB multi-train control system.
