I've been looking into the possibility of using block detection and signals on my layout, and am wondering what would be the best system to work with. I have MRC's Prodigy Express, which I am very happy with, but I do realize it's limitations, particularly in relation to not part of Digitrax's proprietary LocoNet system. Initially I thought I would not be able to use Digitrax at all, beyond the locomotive decoders, but I've stumbled across some information that seems to call that into question. Namely, that Digitrax block detection can actually work with both DC and DCC systems. If that stands to reason, then the block detection units could work with a Non-LocoNet DCC system, as long as I am not wanting to manually control signals from my throttle. That's actually fine by me. Has anybody else done something like this? What would be involved?
