Need some Bachmann DCC wiring help. I have 5 powered rerailers throughout my layout,  my plan was to attach my control board to the first rerailer on one side and then go from the other side of the rerailer to the next one and so on. When I first hook up my main feed it is fine but when I connect the next rerailer the Bachmann controller blinks fast indicating something is not right. Any help would be appreciated. I assumed the out side of the rerailer was to carry power elsewhere, is that incorrect?

I am getting ready to start my HO layout but I am having trouble finding a layout I like. I have a 4x12 table, I am not looking for anything crazy, something I can build some nice scenery around. Looking to have two trains run simultaneously if wanted. I just acquired a lot of easy track with 14 switches, a bunch of straights and turns so I have options. Anyone have any good ideas or plans they wish to share?
