    Hi to all that may read this. DCC the good the bad the ugly ! Maybe, but folks we are now well and truly into the digital world, and there’s no going back.
    Let me enlighten you into a little story that happened about fourteen years ago. I belonged to a camera club when one of the female members bought one of the first digital camera’s, and showed the rest of us how to put the photo’s onto her tiny screened computer.
    Too complicated, It’ll never take off, bloody rubbish, you cant beat proper film, etc etc, were some of the comments from the members, but a couple of fore sighted members including myself said IT WILL CATCH ON, and my word were we right.
    Today there is very little film cameras now, they are almost all digital, and model railways will go the same way. How much cheaper photography is today, now that you don’t have to buy film and have it expensively processed. Like photography Go DIGITAL, go DCC in the end you wont regret it.

    Digital Photography? My first digital camera ate batteries for breakfast every day practically. Photo-processing of film is still only 1/2 that of digital when you include the cost of printing on an inkjet printer! My Nikon FM2 is 100% manual and I have used it for more than 30 years and I still use it frequently! As for DCC, I attended an NMRA convention in Sacramento a few years back and I did take a tour of three model railroads all of whom had recently converted to DCC. Every single layout had to be shutdown during their operating session due to the fact that some trains were ready to run into each other and for other reasons!! Why is this so? Simple. DCC provides a means of controlling the pass transistor that is located in the locomotive. However, it does not provide a means of reliably controlling two locomotives that run off of the same power supply in the same power block. The reason is due to impedance matching! That is to say, even identical locomotives running at different speeds and loads will not have the same speed versus voltage behavior. When two such locomotives operate in the same power block the impedance mismatch between these two locomotives will make simultaneous control of two different locomotives by DCC next to impossible!! So practical DCC operation limits one locomotive per power block and the other locomotives in the same power block must stand at idle to avoid this problem. The other way to work around this issue is to use boosters which are essentially DCC compatible power supplies for different power blocks. Now the cost advantage and operational advantage of DCC starts to vanish compared to pure DC operation. In addition, the need for a dispatcher to control the passing of a train from one power block to another becomes just as important as for pure DC operation. Wiring Advantage for DCC over pure DC? The use of power mosfets and diodes can make pure DC wiring much simpler than legacy DC wiring. Lastly, while DCC is digital after a fashion, the DCC signalling methodology is very crude and inflexible. If changes in the DCC coding are made, one must change out all of the DCC components as well including the DCC sequencer and decoders in each locomotive!! I have about 100 locomotives that I have collected over the years and not one runs by DCC yet! I am contemplating a hybrid pure DC and some sort of digital control that is far better than current DCC technology!

    I really enjoyed your series, DCC The Good, The Bad and the Ugly. I am fairly new to DCC and I purchased the Digitrax Zepher DCS 50 some years ago. It has been what I have been using for testing decoders and changing loco addresses but I don’t see me going much beyond the Zepher with Digitrax equipment as their high end larger systems seem to be problematic based on following the comments in Yahoo Group Digitrax Form over the last few months. There is great help there from very experienced users. I just recently purchased a NCE Power Cab and I am really impressed with the ease of use and after watching your series I am convinced that NCE will be the system for my layouts. I have plans for a small shelf layout in N Scale, a switching layout in On30 and a more functional and larger layout in HO. I also enjoy your on line magazine and look forward to down loading it each month. I store them on an SD card so I can enjoy them on the computer or my tablet. Keep up the great work with your publication.
