I would!!

My HO shelf layout is only 12 x 1 1/2, and a 20 x 20 layout would be a dream. I started MRR a few years ago with N, but after a year, I switched to HO. N was to small for me. When I looked at my layout, I always felt like sitting in an aeroplane and looking down from great height. A second reason – I love scratch building and and it is nearly impossible to do right to scale in N. Most parts are so small, you can’t handle them anymore. It is true that you have to limit yourself when you model HO, but you have to know what is important to you. I never regretted having switched.
OK - here is yur challnege. I am designiong a narro gauge.railroad modeled on an actual area from 1890 to early 1900. Within a circle only 40 miles in diameter you have the folloqwing:
1. Coal mines
2. Gold mines
3. Oil wells
4. Cattle ranching
5. Two towns
6. A small settlement at midpoint (depot, hotel, track crew house and siding + spur
Gold reduction plants (2)
7. One rover with at least two branches
8. A creek with over 20 bridges
9. Extremely steep and rugged mountain gorge (ho,e to creek) with 2 tunnels which connects town #1 with town #2
That is my minimum list. Tell me what you would scrap to make it fit reasonably. Remember that 400 sq. ft. is not the amount of space available for modeling, but the otal space of the layout from side to side minus aisles. My initial projection has the layout running around the walls with an aisle in the middle that branches like a slingshot with top squared off. I'm basing my plan on point to point with switching operatins at origin, terminus (The gold camp and mines, and the midpoint. BTW - at this period in history, there were no turntables used by anyone, just wyes. Basically, one each is needed at origin, terminus and midpoint, and the midpoint is located in a narror steep-walled canyon filled with other stuff as well.
I love to model buildings too, but in HO a decent building has a large footprint. A reduction mill, for example, has a huge footprint.
BTW - anyone else with advice above and beyond the usual "selective compression" is more than wlcome to jump in. I'm not a big fan of "selective compression" because the West, particualry the regions served by mountain narrow gauge railroads, reacts poorly to being compressed. For example, in a mountain narrow gauge point-to point, there can be no other rail lines crossing passing except for the ever-pesent passing sidings.
Anyway, that's my dilemna. When I first conceived it, the space seem very generous to me, too, but after struggling with XTrcCad and looking at the space required for a simple wye in HOn3, I regretfully realized that it wasn't nearly as roomy as it looked.
