I put together an explanation in an email for a certain prolific a$$hat last night, and this morning realized it might be worth sharing with the class.
Here's the orientation image I put together for the next phase of construction. The info below references it.
Harley Davidson is in the corner under the shelf layout (in the bottom left of the drawing). It's backwards from reality, but it's the only way to get it in. I'm thinking two or three tracks to serve the plant. One for 50' boxcars, one for 60' cars. If a third will fit, that'll be for off-spots to wait until there's an actual spot for them.
It's the big plant in the center here:
http://binged.it/1j8Vh7fThe real Windsor Street yard is just to the south there.
Here's the flour mill:
http://binged.it/1j5EEh5. I'd like to capture the flavor of the place, but it doesn't have to be exact. Two tracks there would be good. One would probably be ok too.
The plastics plant is right around the bend:
http://binged.it/1j5GtKP If I can fit two of the Atlas pellet cars in there, I'll be happy. Space for three would be amazing.
Then, going around the loop, I'm thinking it'll be a 2% down grade, whatever I can use from the Woodland scenics riser things to get me just low enough so that the "lower level" is low enough that a trailer on a flat car is below ground level of the yard. I think I need to go 2". Maybe 1.75", so we might need to get creative by lengthening the grade beyond the curve. I'm ok with that, as long as the industrial areas are flat.
The Mt Wolf Paper Warehouse is here:
http://binged.it/1j5JvyJThe crossovers the way they're setup there is actually really important, because the whole point of this part of the layout is for a local to run up out of the yard, work the industries, then turn around and run back. The crossovers there allow that.
Then, there's a tiny stretch of single track, which is an intentional bottleneck, and things go into the "staging" yard. This staging is just three or four tracks, whatever we think we can fit in 5 or so inches in front of and below the existing layout. These shouldn't be hidden, since during an ops session, I'll be actively swapping trains in and out.
The other end of the staging tracks and how they wrap back around will get figured out in phase 3.
