Fred makes some good points: if you can't reach it, it's going to get tiresome really quickly. Another thing that I notice is that you have several curves that look to be under 18" radius. For HO, this is generally considered to be the minimum, and also something to be avoided if possible. With the amount of room that you have available, I'd be looking at 30" minimum. Your track plan reminds me of what we used to call "spaghetti bowl" trackplans: cram as much track as possible into the space available, and to heck with realism, operation as opposed to just running trains, and simplicity. And there's nothing wrong with just "running trains", if that's what appeals to you, but you could have more fun with less track.
With the area that you have available, you could have an around-the-room layout with 30" minimum radii, continuous running if you wanted it, easy access to all parts of the layout, and a layout with the potential to hold your interest for years. Your trackplans remind me of that Family Circus cartoon, where a dotted line shows the path taken by the kid to go to the house next door - your train will be wandering around on a long (and torturous) trip for no apparent reason. You've left no room for sidings, industry, or scenery. In the Weathering Forum, you talk about buying a layout that has most of the trackwork done, because you don't like doing trackwork, but you do like doing scenery. No wonder you don't like doing trackwork!


:-D And your plans will leave little room for scenery, unless you plan on building lots of tunnels.

Take a look at Fred's link, and check out the
Trackplanning Forum here, too.
And please don't misconstrue my comments: there are lots of us here that can assist you in making a layout that you'll truly enjoy, both in the building and the operation. Start by getting some more information that will help you to decide what you really want and then go from there.
