I am using the track I purchased in 1991. This is the fourth layout that I have build (building since you're never finished). All have been fairly large room size. I have had great success with Unitrack. All the moves and new layouts are with the same track I have had since 1991. I have only added track I needed to expand the new layout. And all have been completely different trackplans, but still can use the same track. The current layout is DCC and it operates wonderfully, was easy to wire, both track and turnouts. If you scenic it you can add realism to the "bullet-proof" operation.
Sounds interesting. If they just use an alloy as good as UniTrack it'll be great - no more cleaning. The smaller code seems like a good choice - more realistic, but no flange problems. However, the real test will be the turnouts. If they work as well and look as good as UniTrack, I'll be sold.
I think Unitrack is a great product (I have a loop that I use while my layout is under construction). But as for appearance I disagree with the idea that it can be made to look as good as others. This is probably an "eye of the beholder" thing. BTW, I've seen John Sing's layout. But the most important thing is whether you will be satisfied with it or not. Unfortunately most track choices come with trade-offs, and you must decide which trade-offs are most important to you, as you're the one that will have to live with them. As an example, I used to hand lay all my track in code 40 back in the 1970s. Then I got busy with family, career, etc and this hobby became mostly dormant until about 10 years ago. I'm still busy with my kids just about grown up, and I decided I don't have time to hand lay my track. So after evaluating the options (for me this meant buying samples of all the track options), I decided on Atlas Code 55 as it pleased my eye and meets NMRA standards (this appealed to me as the importance of having track standards became quite evident to me when I was hand laying my track). So again do what makes you happy - be it Peco C55, Peco C80, ME Code 70, Atlas C55, Atlas C80, Shinhara C70, or Kato Unitrack! (or any other options not mentioned).
To date, my layout has about 950 feet and 85 switches, all Atlas C55. But my test loop, and my soon to be designed "office layout" will be built with Uni-Trak. Why? Neither will be "permanent."
Jim - I have not made any progress on the design. Maybe this winter as the rest of the layout gets to a semi-sceniced with wired / control panel state. http://www.trainboard.com/railimages/data/1519/Tiered_Display_and_Casset_Side.JPG Is as far as I have gotten conceptually
