I began playing with this design over the weekend, and thought you might enjoy looking it over.  The outside mainline is O72 minimum, the inside main is O60 minimum (O54).   The grade at the top of the plan transitions to Atlas-O at O54, with one curved O72/O54 turnout on the elevated trestle over the yard.   Room for a turntable!  Not much industry spurs yet (no buildings and etc).  There are two return loops - one elevated and the other around the turntable/yard.  

A work in progress.  2.5% grade (maybe 2.6% - see what the final design has), moderate, with a grade inside the tunnel on the left on the outside main.  6" elevation where the lines cross on the right, and the loop on the left is at 9".  O72 turnouts, except in the yard (O60) and the elevated O72/O54 Atlas.

The design uses one of the compact double cross-overs that I have been posting under different threads, I was curious to see what could be made of the idea.   The center-rail spacing on the double-track mains is 5.25", halfway between the 4.5" of Atlas-O, and the 6" of FasTrack (too wide for my eyes).

I really like this layout! Thanks for sharing. I just adapted this to a smaller version to make iteration #14 on a design I've been playing with for my office.  Compressing the layout horizontally really brought up the slope for me to get enough clearance over the two right hand tracks though, but that's to be expected. Wish I had the room to dedicate to something like this.

Thanks very much for your positive comments, gents!   I might do some more work on this when I have a chance.

Nick, I would be interested in your smaller version.   I was thinking about compressing this idea to O54, in perhaps 5.5' x 10'?

Hello Ken,

I am new to the Forum and the Hobby but have been following several of your layouts and really do appreciate your sharing these designs. I have not made a final decision as to where my layout will be so not sure of the exact size, but a 7 x 13 is do-able in either of my locations.

Thanks again and have a great day,

ThomasT

Have a great day,

My space is limited to a little less than 8' wide, by about 5' deep. The slope obviously had to increase, and it's about a 6% grade, doable by the engines I have.  Getting the clearance over the 2 tracks was tricky too, so the red section starts at a 1" elevation, but here's what I came up with.

Its a very tight layout and very busy as well, but I actually like this more than the design I had posted earlier in this forum.

Hello Webnerdnick,

Very nice looking layout with a lot of tracks in a limited space. Also really like the LONG double dead-end track at the bottom, I will have to work that in on mine.

What is your smallest curve?

Have a great day,

Smallest curve is O-36 (even with the flex), with the larger outside loop being O-45.  It's all Atlas O 3-rail. Credits to Ken for the layout design again. Wish I had an additional 2' of width, which would give more room for things, but, maybe someday that long dead-end will run to another room!

Hello everyone,

I just did a quick measurement of my possible 3 locations and I could have:

A) 8' x 9' the smallest

B) 7-1/2 x 17

C) 6-1/2 x 24 the longest

I would like to have a minimum curve of 0-72 so that every size Loco that I plan to buy would be able to operate anywhere on the track. That pretty much eliminates "A".

Have a great day,

ThomasT

@WebNerdNick try starting your grade a little sooner.  Try to get the “red” switch and track segment up to around 2.5”.  Then work your way up on the outside, and down on the inside as you progress clockwise around the oval.  This should ease your grade some.

Of course then the upper loop will have to be higher than 7.2” but you can keep climbing after you cross the mainline at the far right, so the max grade (which limits train performance) won’t get any steeper.   My $.02.

Creep, coast, and pull.  We're not talking about cold fusion here.
