Hello once more everyone.

How complicated is your layout's rails program? How many DC controllers (blocks) are y'all planning to have?
In full general there needs to be no departure in the wiring regardless of whether y'all have DC or DCC.
Reversing loops will demand special attention in both cases, but that is all I would be concerned nigh.
The idea of using heavy grade wire because it's DCC is likewise a debatable point, the regular wire people accept been using for DC is generally adequate.
The other night at the NMRI we did some accidental experimentation and discovered that DC and DCC can co-exist together much amend than fifty-fifty our optimistic electric department thought.
Nosotros accidentally, (but with repeated success) ran DCC equipped locos from DC to DCC and vice versa with no problems for either arrangement and there was no short on either the DCC system or DC controller. Now admittedly nosotros practise the earthing thing a little different to nigh (we've done abroad with the runway mutual concept) and our DC and DCC controllers are floating (not commoned together) with respect to each other, simply in that location were no other fume and mirrors used...

Basically y'all need to take 2 bus wires that run around under your rails that carry the + and -. You then need to take feeder wires that go from the passenger vehicle wire to the track, therefore you need to drill holes through your benchwork. Doing it this style will provide the all-time electrical current.
Couple of tips in non getting dislocated
one. Always use ii different colours of wire, black and blood-red are commonly used, for the positive and negative
2. Remember of the two rail on your tracks as one being the positive wire and one being the negative wire so y'all won't get your rail feeders mixed upwardly. I drew a couple of diagrams with my layout and used ruby and black pen and this helped alot. This may be extremely helpful for reversing loops.
three. Always characterization your wiring and go along it tidy.
In regards to wiring blocks information technology depends on the size of your layout.
Only a note, I found that DC is alot of fun when yous wire upward your layout using blocks and makes you think a scrap more, if thats your thing. I personally on my layout don't run across the demand for DCC merely this is my layout.
To wire blocks you create a rail gap to isolate sections of rails from each other and then that they can exist controlled seperately. To create a rail gap just remove the rails joiners at a indicate and make certain the track are not touching. Information technology is all-time to exam these gaps before making ot permanent.
Hope this helps in some way

Note that all that scubs has said tin be done for both systems and as Aaron pointed out the wiring is about the same. Forget those ads you encounter for DCC that say you only need ii wires to do everything, on a simple oval of runway this may be true, simply a larger layout needs just almost the same corporeality of wiring with a few exceptions that a DC one would accept! 8)

Wire it for DC then when you want to modify, either cutting the output from your controller and supersede it with the DCC output, or meliorate still insert a DPDT relay or switch to allow instant and safe switching between the two systems. Annotation that you must switch both wires so that the two systems are isolated.
Nosotros accidentally, (but with repeated success) ran DCC equipped locos from DC to DCC and vice versa with no issues for either system and in that location was no short on either the DCC system or DC controller. Now admittedly we practice the earthing thing a picayune dissimilar to most (we've done abroad with the rail common concept) and our DC and DCC controllers are floating (not commoned together) with respect to each other, but there were no other fume and mirrors used...
Surprising what you can learn by accident, our piffling *test* only had a very small pause as the loco crossed the join while the bit did information technology's thinking just no other problems.

My personal opinion on the field of study - DCC wiring is easier and less complex than DC, requiring less time and less wire. Yes, you still need autobus wires around to each flake of track if you do it properly. However, savings are made when information technology comes to betoken motors and the similar. You can save a lot of wire past cutting out the spaghetti between the bespeak motors and the command panel. Truthful, it's more than expensive (I know, I've got most of my points decoderised) - but it saves a lot of time.
You too don't need equally many blocks - in DC you may need a lot of blocks and isolation points, particularly in yards, and all the associated switches etc. In DCC you only "demand" blocks for power districts etc, or for railroad train detection.
We accidentally, (but with repeated success) ran DCC equipped locos from DC to DCC and vice versa with no problems for either organization and there was no short on either the DCC organization or DC controller. Now absolutely nosotros do the earthing thing a little different to most (we've washed abroad with the track common concept) and our DC and DCC controllers are floating (not commoned together) with respect to each other, but at that place were no other smoke and mirrors used...
Seeing as "restriction on DC" features are becomming pretty much standard in DCC fries, running from one to the other doesn't appear besides fraught with danger. That said, it'due south a good thing to know. Mixing systems can come up in handy for the occasion that someone brings their not-chipped loco in. And occasionally I get irritated that before any of my trains tin can turn a bike I have to put a chip in 'em.
