6x18 layout overhaul ideas

That's already a nice layout!  What you could do, without ripping up too much of what's already there, would be to make the upper track two big reversing loops.  It's not a big change but it will serve to reverse the consist every other run, at both ends, and will make it more visually interesting.  I know there are ways to tweak power output on a grade so conventional engings maintain speed but I have never gotten into that, and I think it might be more than you are really looking to get into.

What else would you like to do?  I'm seeing a military theme, I think I would go with a troop transport set and maybe play that up - picking up enlisted men in small town america, traveling to a military base, factories producing airplane parts, maybe even put in a harbor with part of an aircraft carrier. 

I am getting ready to start over with my layout as well, and all I can tell you is that in many ways, less is more.  I tried to cram in too much, this time I am adding an elevated level but doing more with scenery rather than accessories. 

Here is a link to my post on a 6x18 design that I am pretty close to running with.  I am trying to accomplish a longer “main” by using multiple levels.  Maybe this will give you some other ideas.

I understand your desire for longer runs. I'm contemplating revamping my planned expansion to double the working length.

I have 2 loops, and I'm thinking I'll connect them and cross one to the other in back via grades and a tunnel. This will let the train go around the entire layout twice before ending up at the start point.

Drawback: Only one direction of travel for all trains on the layout unless I turn them all around at once.

Possible fix, 4 loops of track paired and crossing... Eats lots of space tho.

This makes adding loading areas for your freight and passengers harder.

I do agree with Rich, It's far more interesting to me with reasons for the trains to run.
