19 X 12 space need ideas

They say a picture is worth 1000 words. If you can draw out the room with the door/window locations, snap a photo and upload it, it makes things easier to figure out.

An O80 circle has a 7'8" diameter, no?.  In a 12' X 19' space you are going to have to go around the walls with a duck under or lift bridge.  To do any loops back on themselves you can use O60 max.  Also incorporating 4- 4' bridges requires a bit of space between curvatures of the track.  That's a good sized space, but you are putting Large sized elements into the equation.  I would start with 2 mainline loops around the area, then plug in your other desires. 

A good idea is to draw out your space on 1/4" graph paper. 1/4" = 1' on the graph paper? 1" = 4' in O scale.  Same deal.  Draw out a 12' X 19' rectangle and see what you can fit in there using 7'8" diameter curves.  Being realistic, you are very limited.

Yes space is always at a premium with O gauge.  Curves eat real estate fast, That said if you want an island layout that's up to you.  Might be able to fit 090 and stiil have  several feet to walk around. If its Atlas track your 4 " center rail to center rail. Reach is  an issue so you would need access hatches. You can do differing levels or all on the same level. One with 090 curves one with 080 or 072, or go smaller, 072 and 054. Or go around the walls and put a peninsula of your longer 19' run in the middle with a Yard or engine service area.

William, that should be 6'-8".

Here's a plan that could be adapted:

and another:

yet another:

All of these could be modified/expanded to fit in a 12x19 space, depending on where the doors/windows are.

No problem Bro!  I've had a run-in or 2 with numbers not being what I thought too

It's usually AFTER I spend the $$$ that I find out I had a slight miscalculation
