Hi, I am trying to decide what beginner DCC system I want to invest in. I know nothing about the world of DCC but I have it narrowed down to either the Digitrax Zephyr or the NCE Power Cab system. My HO layout is going to be 2 ft wide and built around the perimeter of my 12 x 12 room. I want to have a system that can handle 3 trains at a time and be able to run at least 2 cabs for my son and I. Can you give me some insight as to what would work best for me? I don't quite understand the comparison specs of each system. I do plan to expand my layout beyond my 12 x 12 room in the future, but not now. Any information will be helpful. Thanks, Mark
A couple of things I think you should consider before buying:
- are you going to be happy with a fixed power pack form factor such as Zephyr, given that your layout goes around the room behind you? If you truly want walk-around control, then I recommend you price out your end-state solution with both NCE and Digitrax (and perhaps MRC, as well). That way, your first purchase should be the 1st step towards that end state, with little wastage along the way.
- in thinking about your end state requirements - you state running 3 trains with 2 cabs. Is your layout truly set up for running 1 train unattended while the 2 of you focus on running the remaining 2 trains? Or, do you really need/want 3 cabs down the road? If there's only going to be the 2 of you, will you really run a 3rd train? Going to 3 cabs with NCE means you need a Smart Booster to handle the extra cab.
- but digging a little further - walk-around means portable throttles that plug into plates mounted on the layout, usually in the fascia. Is that acceptable, or do you really want wireless throttles?
If using walk-around control, the Zephyr isn't really functional as a throttle, but it does work well as a command station and booster with the throttles plugging in to the Loconet bus. So you would need a Zephyr and 2-3 throttles, plus 4-6 plug-in plates. Present Digitrax wireless requires you to plug in to change, acquire, or dispatch locomotives so some plates would still be needed even with wireless. Eventually, Digitrax will release a duplex radio system that should do away with the need for plugging in.
In its base state, the NCE PowerCab cannot be unplugged - it shuts down the system as soon as you do. A Smart Booster is needed allow unplugging the PowerCab throttle, and permit the use of 4 throttles instead of 2. Of course, second and possibly third throttles, and the plug-in plates will be needed in the end state. Or go with the higher end NCE system from the beginning, which does not have the limitations of the PowerCab and/or Smart Booster. A wireless system is available from NCE should you prefer, and does not require plugging in (do away with the plates around the layout).
MRC's Prodigy Advance2 or Wireless has basically the same capabilities as the NCE PowerCab
without the expansion limitations. But it costs more to begin with, and the plug-in plates do, too.
Finally, both NCE and Digitrax offer reasonably priced computer interfaces that allow you to program your decoders using the excellent open source (free) JMRI/Decoder Pro software. Decoder Pro is by far the easiest way to set, record, and test CVs in your decoders. MRC offers (coming real soon!) a wireless computer interface (many more $$) with proprietary software instead of Decoder Pro. Since it hasn't arrived yet, nobody knows how good the MRC interface software is/isn't, nor whether it will work with all makes of decoders like Decoder Pro does. If the computer interface is important to you (and it does help significantly if you have more than 3-4 locomotives), then I would stay away from MRC.
By planning your end state ahead of time, you can get an idea of what total costs are for each system, and making sure you don't waste $$ on a dead end, growth-wise.
my thoughts, your choices
