Question about block wiring and eventually using command control

Actually wiring for DCS is very similar to our old cab control with the center off toggles creating blocks  and the ability to select a or b handle on our trusty KWs for each block.

Forget about the toggles  but the blocks created with cab control work well for dcs.  

It wouldn't` take much to go from conventional cab control blocks  to command dcs with Just a few minor wiring changes.

TMCC is even easier with one wire from the command base to an outside rail.

  To cover all the bases fast, the signals need to be delivered to all blocks. Achieving the suggested "star or homerun wiring" may require changes. Those two wiring terms are your next "homework assignment"  

Thanks, all, for the responses. I remembered that Lionel used the common rail, so isn't affected by the isolated blocks, and with DCS it was relatively easy to use pre done isolated blocks with DCS (obviously, the toggle switches would not be used except if I wanted to have a block unpowered). I also remember someone saying at a demo I saw of DCS that having isolated blocks and feeding the dcs signal to each block would allow for a stronger signal, and that if you fed multiple DCS control wires on track not isolated you could get 'signal bleed' that could cause problems (or something like that), so isolating sections made sense. Anyway, before I get to the wiring (still a ways away), I plan on doing a lot of reading up, getting Barry's DCS book and finding something good on legacy as well. 

Barry's book describes it well. I followed as closely as I could and everything works great. I later added Legacy by tying the four common outputs on the TIU together and connecting the Legacy signal at the TIU. I don't have a huge layout like some folks do though, only 6'x16', but there are plans for expansion to at least double that and add a second level. That is if I ever get to it...I thought I would be done with the expansion by now, have not even decided on a track plan so far. 

I don't remember if it's in Barry's book (might be), but if you use track that has the outside rails separate then wither tie them together or make sure you use the same one throughout the layout. Many say to use both which is probably the best way, but I only used one because I wanted to add signaling and other things using isolated rails.
