Looking to redo a different new layout. Currently have  o scale Fastrack, but thinking of maybe switching over to Atlas.  Seems like fastrack takes up more room on layout and is louder.  I would like to do the biggest curve I can and have an upper level if possible.  I have working dimensions below, maybe not enough space to get a bigger curve ? Any Ideas ?  T.Y.001

My initial impression is you don't have much room for larger curves. A couple of things. Yes, FasTrack is noisy. And given the track size, (036/048/060/072) you end up with 6" track spacing. That can be tightened-up.

 As an example, the following is an initial track plan for our club's new modular layout. The proposed outer track was 060. The dimension for the nominal benchwork width is 72". In an effort to make more room for scenery, the outer loop was subsequently eliminated. The two remaining inner loops are 048/036.

If you have room to change your lower right dimension to 6' and the carry the 6' dimension on the left all the way across to the right, you can easily step-up to 060. If this layout is in a corner, I'd plan for access hatches.

Here's a basic perimeter run using O54 curves in the upper corners, O45 on the left and O27 on the right.

What are the limitations dictating the table size? As it is you're going to have reach issues to the back unless you add access hatches (assuming left, right and back sides are against walls).

The 3x6' section on the lower right; is that locked or can that change? As Dave correctly illustrated, you're stuck with 027 in that area. That could put a major cramp on things.

Were it mine, I'd be looking at a folded double dog bone layout. Something on the order of this....Loops

Throw some elevation into the equation and you can cross on over top of the other.

The right side which is 10' long and 3 ' wide I could extend the 3' section some more outward.  how much room would I need ?  Maybe to 6'  I was trying to give my self some working room but if I need to I could do the 6' Since I will need sidings and I have 2 bridges to use.  I tried to do this with the Scarm site but it was limited since I don't have paid version.  Thanks for the help.  Would this be the Atlas track ? 

Here's something else to consider. Back curves are Atlas O54 and others are Atlas O45. Since you said the left side is open and I reduced the width of the top, access should be within reason all the way around. FWIW, you can do this in the trial version of SCARM, you just have to break it into sections and work on them separately.
