What I mean by aDC common rail system is this: one rail is connected to the ground and connected throughout the layout. The other rail may be switched between + and-, depending on the direction desired. All separation into blocks (except reverse loops and wyes) is made in the non ground rail, which is called the control rail. That much I know.
How does this work? My concept of "ground" is and always has been somewhat hazy, except for vegetable gardens. Presumably, a system that delivers DC to locomotives and AC to action cars etc could also be termed a common rail system, but that is not what I am asking about.
