>And I would like to consider return loops so does this feature use up address capacity?
As I understand it, these not inexpensive devices, are attached to the track power and detect the short when the train wheels bridge the gap on entering / leaving the return loop. Once the short is detected, they swap the polarity of the feed in the return loop which removes the short. All this in the blink of an eye, which maybe explains the cost.
>I may have a pool of chips which I can move around depending on which locos I want to have a DCC play with.
After Doug's review on the Hornby Britannia and other people's experience with the Hornby A3, I think your options are limited to:-
1) Permanent chipping these exceptional locomotives
2) Not buying them at all
3) Fitting an extension harness that goes back to the tender and having a socket in there which you drop something like the cable free Lenz Silver into - just lift the coal off, and hack out the insides of the tender while you're at it
4) Stick with DC.
5) Build a Z gauge layout in a brief case

>Signals - 1 address each (semaphore). DCC really doesn't handle MAS
I found Viessmann's catalogue for 2007/2008 (and that's not a typo) posted on lokshop last night. They are doing DCC versions of their German MAS. It would be interesting to know how they have "addressed" this problem. It wouldn't surprise me if it used function codes.

That's a very valuable experiment Doug.
It would be interesting to find out which other command stations change CV29 to "short" addressing when they program CV1. The fact that the Lenz does this makes sense, but is frustrating to those that want to make the best of both worlds.
One question: Did CV17 / CV18 retain the 7003 address?

MMaD, you've obviously got a lot more experience in the use of DCC than most of the rest of us and I assume are a contented Digitrax user. Are there any features that you feel are missing from your system or it does make "great coffee" and that's enough for you?

This is a sincere question with no ulterior motive.
