Thats a great interpretation of the plan. It would be very tempting to make it shorter or narrower in N scale but somehow you've built a micro layout with more country than rail. There is something in all of us that usually means we lay rail parallel to the edge of the benchwork. I think slewing the tracks at an angle and a bit of unoccupied real estate makes the layout appear generous. The original Piano line was littered with detail, but for my money a grain elevator as the focal point, bland scenery, and restrained detailing would keep the look. Looking forward to the rest of the build.
Yep, a layout with too much track simply isn't my taste. I always thought the Piano Line was the more "generous" design anyway.
I do plan to go all out with detail, but like you, I have a limited budget. I already spent April's allowance on N scale freight cars and a new locomotive. So now I have to save for a couple months and get track, static grass, styrene, a couple more Woodland Scenics Learning kits (great for small layouts, BTW) and, of course, all the details I can muster. For right now though, my main focus will e getting track, roadbed, and wiring the layout so I have something to run.
