Hi Bob, I've been using DCC for several years now. I love the freedom from block wiring. It's not so much the wiring I disliked but the requirement of throwing switches to keep the throttle controlling a given train as it progressed around the layout. Now, DCC is capable of doing much more, and it will no doubt grow even more capable. However, other than adding sound as my budget allows, I don't use the other functions. I have no desire to throw turnouts from my throttle. I would like to add signalling (time to wire those blocks again!) but frankly am not up to it at this time. I am lacking in computer knowledge and the desire to obtain it, you would think (correctly) that my DCC knowledge would be similarly constrained. Signalling (Digitrax, as far as I know the others don't offer it yet) requires computer interface, unless a friend appears who wants to guide me it won't be happening for a long while. But...
The talk you hear about DCC being complex is false. In its basic form, controlling locos, it is very easy! Installing decoders in some of the older locos can be a challange. I've hard wired many, in Athearn, Life Like P2k (older without sockets) Stewart, etc, none were a problem as long as you have basic soldering skills. Often, figuring out how to get the shell off is the hardest part! Most of the new locos (I'm talking HO) have sockets now so installation takes a couple minutes. Programming? If I can do it anyone can. Again, I don't use extra lighting functions like strobes or ditch lights, I understand these are sometimes confusing to program. Probably most people would have less trouble than I with that. The reason DCC is perceived as difficult, I think, is that it offers so much more above the basic functions I use.
The only advise I can offer is in regard to reverse blocks. Use the reverse modules from Tonys (
www.ttx-dcc.com) they work great! I had no luck with the MRC ones, I have a couple laying around if anyone wants them. They worked unreliably and not at all with steam locos. I believe that is because the lead axle on a steam loco is insulated on one side and the design of the MRC unit must require a current flow. Diesels would operate it, tho sometimes with a short delay. Using Tony's, you can not even see a light flicker when the gaps are crossed. Digitrax makes a reverse module, I haven't bought one so can't comment on it from first hand experience, but having read comments on the Yahoo list, it's not for me! I like it simple, thank you.
Concerning brands, I would think they all are good, I'm happy with my Digitrax, a friend has NCE, it seems fine too. I've heard bad things about MRC and early Atlas units. Programming limitations. BTW, the Atlas decoder equipped locos are great.
I hope some of this is helpful. I'd be glad to answer any questions you have about the basics but others will have to help beyond that.
Have fun, its great!
