hello everyone , this is probably a simple question so excuse me for my lack of smarts here , I'm running a small layout with a few lionchief plus engines that is fast expanding , mth rail king has a lot of engines I'm interested in as they fit the need of what I'm doing I would like to get mth dcs equipped , so my question is if I get the dcs remote and track interface unit and wire it into my layout what rail king engines are out of the box dcs ready , as in how can I distinguish them from conventional rail king engines when looking to buy , and are older engines upgrade able , can I get dcs chips for older conventional engines and convert them to run on my layout ? I know about ps1 2 and 3 now are those just sound boards on conventional engines or are all ps equipped engines dcs ready , any help filling in the blanks here would be awesome thanks all!!
