Change of plan...?
I was cruising Youtube and found this.

for some reason, RBR's micro layout serving just the grain elevator intrigued me. It's a yard of track, a runaround, and a high-profile structure all in one.
But his is only 60" long. I have given myself 96" to work with...
So here is RBR's original 18"x60" switcher simply expanded to fill 18"x96"

The first revision. Things adjusted around, but largely the same. It seemed like a waste of room to have 8' just to serve a grain elevator, so I added a flour/sugar mill.

the only problem is that RBR's current expansion of his layout extends the spur for the grain elevator and gives the elevator it's own lead/siding. My above plan permanently captures the spur. I had the idea of using a GE 25-tonner owned by the elevator, but why have a dedicated locomotive for such a small task. And my intent is to design this layout to be switched by a SD38 without aid. (10" for the loco and 8" per grain hopper is the standard I'm using.)
So I come up with this, one which I'm fairly happy with.

The runaround, instead of holding two cars, holds four. The right lead is enough for the loco and two cars, the left runaround lead holds one car with the loco. The grain elevator will probably lose it's shed, or shrink to a sub roof. So there are four customers; the elevator, the mill, and the team track which usually holds one LPG tanker for an offsite dealer too small to have it's own tank (but a sufficient list of customers to justify rail service) and a spot for random traffic as well. I imagine the mill putting out bagged flour and sugar as this is current-day, I refuse to pay $30 a pop for Atlas pressuraides, and I need a source of boxcar traffic to balance out the grain hoppers.
The only thing that worries me...RBR posted a picture of his wiring diagram for that Shinohara 3-way...

Nah, if I can 'properly' retrofit a two-speed E-fan into my RX7 that turnout shouldn't be hard.
