I may ballast the three track pieces, but it isn't required for judging and I fear gluing up the works.
When I started planning for the handlaid track requirement a year ago I was pretty nervous. I had never done it before and I figured it would be really difficult unless I used the FastTracks tools (which, to my mind, seemed like cheating). But, some excellent articles in Model Railroader and Garden Railways magazines walked me through the hard parts. Since I built them in G scale, I didn't have access to commercial NMRA gauges so I made my own. I wish someone would offer them in laser-cut acrylic or perhaps metal, but because of the loose tolerances all over the place in large scale it is probably too late to get industry conformance to anything.
I am glad the NMRA MMR program pushed me to develop these new skills. I think it was pretty fun to cut and glue down the ties, stain them, spike down the rail with real spikes, and then run a train over it. I made it myself! There is an immense amount of satisfaction in saying that. And, I am now even closer to finishing up my Civil merit badge requirements too, which is pretty exciting.
