Hi all.  i am trying to plan ahead here so i don't have the items I need to wire to check specs for myself.  Hopefully your insight and advice can help me out.  Here is my situation:

I like the lighted MP bumpers. I guess I just like shiny things, like most men.  But these things are powered off the rails and common sense tells me that I will need all my juice from my Zephyr for my locomotives. I thought about putting insulating joiners on these bumpers and wiring them separately. At present, I ran 3 wires under my bench work. Two for the rails and one for accessories.  But these bumpers would need two wires (one for each rail) so I would need to run a second accessories wire.  Should I go this route? I  also plan on have MP lighted structures and some lighted billboards, traffic lights, signals, etc.  Do all these accessories require two wires to illuminate, or just one? And, since the bumpers run off the rails, they require DC power right? Do those other accessories require AC? Because that would be another issue...and more wires.   Thanks.

Two wires

All of your accessories will require two wires.  You want to keep your track power isolated from all other electrical "stuff".  Remember that your track feeds are supplying both power and digital command signals via the tracks to your locomotives.  You want to keep that signal as clean as possible.

Now as far as your MP bumper, my suggestion would be to disconnect the light from the track and run two new separate power feeds.  Further, get rid of the incandescent bulb, which creates heat and will not last long, with an LED.  For around $2.00, every place you use an incandescent an LED with the proper dropping resistor can be inserted.  The LED will outlive you and create no heat.  Take it from a graduate of the "school of hard electrical knocks".  The first incandescent bulb that fails on your layout (typically the first time its powered) will be the one that is the farthest away in the tightest location..........
