A few suggestions

First it looks Like you have a good mix of industries and lots of switching opportunities. What is the theme and/era you are shooting for. It will help to determine car size to fit in the industries and help decided what changes need or could be made.

Second I think the tail on the left side is to short to serve the two good sized industries you have on the layout edge. 

Third I think that  the elevator would be better to be placed as a backdrop building in your yard area.

Last I think I would remove or move the brown building so it is not on a trailing point move.  These changes would allow you to have less bench work and less reaching over things. Also I feel it would make it more prototypical.

Removable track to the left?

Yes, the tail on the left does seem short for more than one car. You may not want to have a permanent structure extending any further.  Can you add a removable track on that end?  Perhaps a 2 or 3 foot board without scenery that can clip on and be stored when not in use?

Runarounds

Hi Calvin,

I wonder if you could kill several birds with one stone by consolidating the two runarounds on each end of the layout into one in the curve in the upper right corner.  That could give you more yard and/or industry capacity on the right end and more headroom for your switchback on the left.  If you were to move the grain elevator behind the yard as Greg suggested and put the elevator spur along the backdrop where your main is now, you could angle the yard and main toward the front for better access, allowing space between them and the new elevator spur for grain bins and the elevator.

In the breaks between tearing

In the breaks between tearing down my big layout, I have put a bit of time into brainstorming a better version of the plan in my OP.  Now that the room is cleared out I noticed that there is a large protrusion in the corner.  It is either a large beam or pipe embedded in the wall.  Unfortunately, it reduces my available room to 7'X7'.  I decided to contain the plan to a single industry, a paper mill.  Joe, your idea to put the runaround in the corner helped save a lot of room, thank you.  My main goal in this redesign was the get rid of the tail that stuck out.  I wanted to keep this to two modules that will fit in my Tahoe in case I wanted to drag it to the local show. 

Looks great

That looks great Calvin.  I love the single industry theme.  Will this layout be something you can integrate into your new primary layout as you rebuild?

Will the yard, or maybe the runaround, act as your connection to the outside world?  Perhaps with inbound cars left there by a road train (staged there by hand) for distribution during your op session, and then the outbounds left there at the end of the session for the next road train to retrieve?

By the way, I really like your choice of the BAR as a prototype.  Looking over your roster on your blog the other day, it looks like we've got a lot in common there.

Boiler

Only suggestion would be to make the Boiler an Implied industry, have the the conveyors go to the edge of hte layout or to the backdrop where the structure could be modeled as a building flat or picture.

You could then extend the three tracks at the bottom of the layout to the edge and use it as an arrival departure yard.

Here is an idea

What software was used

@Calvin and Greg, what software are you guys using? Looks like rather simple (which I like). I have 3rd Planit and cant stand the learning curve with it. Especially for a small layout.

I use Anyrail

I am using Anyrail's free version, which has worked out fine since i am not building very large layouts. I think it limits you to 50 pieces, that could be and 50 items you select, track, buildings, scenery, etc. If I was doing nay more in depth designs or large layouts I would probably go ahead and buy the full version.

The track library is very very extensive, but it does not have much for structures or other shapes. This has been fine with me as I usually don't build buildings using the instructions anyway.

I have the full version of

I have the full version of AnyRail5.  It allows you to download objects, such as structures, that other users have drawn up and submitted.  It really fleshes out the object libraries that you have to work with.  The free version is really great though, it's nice when a company will let you use trial software indefinitely instead of just for a few weeks or even days.
