This Christmas, I built an N-scale layout on a 4'x4'x3/4" plywood sheet. It's a sort of a folded-over figure 8, using the Atlas pier set to get the proper elevation for the crossover. So I have (sort of) two concentric circles of track, with plenty of space in the center for my Christmas tree. I added some mountains and tunnels made from ordinary storm window screen material and some plaster cloth, and wired some little bulbs inside the tunnels, and the finished product is pretty impressive, given the relatively small effort and cost.
I never had much interest in model trains before, and I took on the project mostly to impress my four (going-on-five) year old daughter. I'd hoped that she might get involved in the construction phase a little with me - maybe glue on some lichens and smear some paint on the scenery - but I apparently over-estimated the fine motor skills of five year olds, and that didn't exactly work out. But we had some fun anyway.
Now, of course, I'm full of ideas for next year's layout. I'd like to keep the 4x4 footprint, with the tree in the center. But I'd like to run two trains and I'd like to assemble my next layout with flex track, instead of soldering together all those little 5" pieces. I'll also probably implement the tunnel lights in sockets, instead of hard-wiring those little grain-of-wheat bulbs, so that they're more easily replaced when they burn out.
I have some questions, and I suspect you are the guys to ask :)
I got a dozen pieces of Atlas code 80 flex track, and I've been putzing around with the stuff. I notice that one rail sort of "floats" on the ties, while the other appears to be "captive." Is there a right way to use this feature? Should I be planning to have the floating rail on the inside side of a turn or the outside? Should I plan to solder floaters to floaters and captives to captives or should I stagger them? Or does this not matter at all?
Also, I'd like to implement multiple elevations with the 2" foam board material I've seen used in a Model Railroad magazine. I've never seen or worked with the stuff before, but it's implied that it's a common building material, and I assume I can get it at a builder's supply. Is there any specific type or grade of this material that's the "right" stuff? How would I attach something such as the Atlas bridge piers to this material? Will it take a nail, or should I plan on using adhesives? Is it paintable? Will it deform very easily if I solder too near to it?
TIA!
