I guess it depends on what one considers running locomotives at once. I am a firm believer in having one control for each train rolling on the layout at any given time. What they are talking about is getting one train moving with the controller and then switching channels to another locomotive and getting it rolling, etc. One then has to switch back and forth. In this regard all the DCC systems are the same, but it is also why one can add additional throttles.
I don't know if what you learned about the NCE power cab means it can have only two more throttles or if it just means it can only switch between three. My NCE is the PRO cab. I have not yet encountered any sort of limit with it. I've been at sessions where we have had over 24 trains plus running simultaneously.
As for the Bachmann vs Atlas sets I have no first hand experience with either. I have always trusted Atlas (45+ years now) in both HO and N scales. Bachmann in the last two decades has really stepped up their game especially with the Spectrum units. So I would be torn. Two loco's and a starter DCC system is pretty tempting. On the other hand while their EZ-track is easy and nickel silver it is NOT cheap and not nearly as flexible as normal Atlas track. If the Atlas set comes with Atlas "TruTrack" I find that even less flexible. Straight Atlas track without the built on roadbed still wins the sectional track contest every time. Don't know if this babbling is helping or not. I would not be afraid of the Bachmann set as I would have 20 years ago.
No this is good stuff. I am, after reading the replies, seriously just considering buying flextrack and piecing my system together instead of buying a starter set.
However, the wife said no to spending large amounts, so I have about $100 to get started until February (high spending limits on my birthday). I own 2 DC locos (to my knowledge lol).
If I were to, say, buy a DCC Compatible Power Pack in addition to the atlas flex track and terminal tracks, etc. what does that look like when I do buy the DCC system? The Bachmann power pack says DCC compatible, I have absolutely no idea what that means, and cannot find anywhere on the internet that explains it.
I don't mind learning to solder and stuff or even hooking up complicated electrical systems, that part is very alluring to me when thinking about building my set.
I guess my real question is: If I buy my system in parts, and start with that DC power pack (compatible with DCC), how hard will it be to upgrade to DCC in February?
