http://www.modeltrainclub.org/club.html Why Some Model Railroaders Prefer DCC operation over DC train operation and vice versa. For those starting out in the model railroad hobby a DCC system is usually the best option for a new model railway layout, because it is way the model train hobby is moving. However, that's not to say there isn't still a place for DC operation in model railways. And, if you have been using DC for many years then you might not be interested in changing over and learning a new DCC system for your model railroad layout. Although in saying that, if as a model railroader, you can understand the various workings of DC, then a DCC system will be a breeze to get your head around. At the end of the day each model train system has different features and advantages over the other. So, if you are into model trains or just like watching model railroads then watch this video to learn more about DCC and model trains.
