Here is the redesign I did on the Tyco Layout expander plan to eliminate its shortcomings like S curves, and the single crossover between the two loops. The track pieces are Atlas Code 83, but code 100 could be substituted. This is mainly because the plan uses 1/3 sections of 22" radius track in several places, which is not available in Code 100.
Track
500, H0 Atlas Code 83, Flex 36". 1 (Minimum number of units: 1)
510, H0 Atlas Code 83, Straight 9". (bulk) 18
512, H0 Atlas Code 83, Curve radius 18", angle 30º (bulk) 35
518, H0 Atlas Code 83, Buffer/Bumper 1.26". 3
521, H0 Atlas Code 83, Straight 6". 4
522, H0 Atlas Code 83, Straight 3". 4
524-1¼, H0 Atlas Code 83, Straight 1.25". 1
524-1½, H0 Atlas Code 83, Straight 1.5". 2
524-2, H0 Atlas Code 83, Straight 2". 1
524-2½, H0 Atlas Code 83, Straight 2.5". 1
534, H0 Atlas Code 83, Curve radius 18", angle 10º 5
537, H0 Atlas Code 83, Curve radius 22", angle 7.5º 2
561, H0 Atlas Code 83, #4. Left turnout 9". (custom) 5
562, H0 Atlas Code 83, #4. Right turnout 9". (custom) 4

Very clever reworking. Exactly like you say, it
eliminates several problem areas that really
doomed the original.

Nice! Maybe for a future 4x8 HO-scale layout I may build (4x8 if I'm cramped on space, that is), I'll try doing that, but with Bachmann nickel-silver E-Z Track. I mean, sure, it's Code 100, but it's easy to keep aligned, and it comes in #4 turnouts. But there aren't any 1/3 sections of 22" radius track, but it's not too hard to cut the track into such lengths and bond them with duct tape or something, similar to on my current layout when I'd have a TYCO Prestomatic accessory (9" Atlas Code-100 straight track on the ramp) or a TYCO operating railroad crossing connected to the E-Z Track by such means.
For building such a layout, I would also use DCC, eliminating the needs of all those gaps and blocking. (Heck, the original TYCO Layout Expander System plan built without any gaps or blocking definitely makes for a great first-time DCC layout!)

I'm not sure this layout could be built on a 4x8 with EZ track. The geometry of the switches is totally different and EZ track takes up alot more space than Atlas. Take your layout for example. Had you used Atlas track, you'd have your tracks much closer together like the real railroads. I'm not saying you couldn't do it. But you'd need to widen the table by about 6 inches of so.
