Reply to "2-Rail Power and Control for a Beginner"

2 rail generally uses variable DC voltage with polarity determining direction in conventional operation. For remote/command control, generally a fixed DC voltage is used with DCC. When going from 3 rail to 2, reverse loop/block wiring is also thrown into the mix (as opposite rails would meet up and short out). The above is true for just about all gauges.
