Updated 12/14/2021: Today I have been working on adding structural detail to the outer column assemblies. Here's my first effort along with a jig I designed for the task.
I have also been painting the Open Hearth's smokestacks. Here's one in the paint booth. The red circle indicates the hole for the smoke pipe (plastic tubing).
More when I know it.

George thanks for the update.
This is going to be an impressive building for sure

Very impressive details, George.

Very impressive details, George. Thank you. The devil and the genius (if any  ) are in the details.

Updated 12/18/2021:
All 10 column assemblies have received their cross-brace "lace-work" on both sides. I still have one outer column assembly waiting on gussets. It might be time to turn my attention back to finishing the roof trusses (for as long as I have parts). I'm waiting on some parts for that assembly as well.

Updated 12/23/2021: I find myself blocked on several projects for a lack of parts, so I thought I'd take the opportunity to do a sort of "round-up status" report. As usual, I am attacking (or at least dreaming) on many fronts. Currently in play: - Weirton Steel Open Hearth is under construction. I have a bunch of Plastruct on order and very little in hand. I am looking into the details of the oven construction and planning its dimensions. The smoke generator for the stacks is here and operational. I’ve completed the proof of concept with it and the ventilation system. The smokestacks and their lights are here; I still need the safety cages and ladders to proceed. Smokestacks are in the process of being painted. The Arduino and some of the components for controlling the mill’s operation are here. I am exploring the electrical connection of components and researching the programming of the simulation. This is a huge project.
- “H” line pole fixture has been completed. Eventually, you may read of this project in print. In the meantime, I am having it merit judged at the January NMRA division meeting (never done that before - don't know what to expect).
- Steubenville PRR Station: I just placed a large order for detail parts with Scale City Designs. One of the parts is the PRR umbrella style platform roof support. Some information from a Panhandle modeler friend revealed that the supports were 18' 8" apart. I am going to use a 20' separation between supports. Even so, my 65" (260 s') long platform will require 14 supports. By the way, the prototype platform was much longer. The windows for this building were 3D printed earlier this year. I hope to start this project in spring of next year.
- Highland & Superior: All 6 of the HO houses for this area behind and above the Steubenville station are complete. I still need to figure out the hillside, street, and tunnel next to the station before I get that going. But I want to start that early in 2022.
That's the score at the moment. More when I know it.

You've got a lot going on George. Good luck with these upcoming projects.
How does the NMRA feel about your layout being 3 rail rather than 2 rail? Will they be judging the fixture or the poles?

Now that's what I like, a modeler with a detailed plan. Good luck with these projects, George.

I really haven't encountered much grief about the layout being 3 rail. At least, not to my face. I have been asked why I chose 3-rail. My answer includes: - I really don't see the middle rail any more. It doesn't bother me. And anyone who focuses on the trains and the layout ceases to see, too.
- I like the electrical simplicity of 3-rail; no polarity reversals or complex electrical gymnastics at the turnouts.
- The oversized wheel flanges and couplers lead to improved reliability. That is extremely important to me. I hate the idea of pushing trains with my hand.
- Reduced cost vs. 2-rail O scale. My 3-rail steam locomotives have cost anywhere from $200-600. The equivalent 2-rail versions would be $800-2500.
I expect the fixture to be judged. It's considered a structure. What's next to it is irrelevant.

Updated 1/6/2022: Finally got myself off the dime to start working on the Open Hearth roof trusses again. Turns out I needed to adjust the jig first. The positions of the uprights were a bit off. I am using some Plastruct rectangular rods for guidance; they are glued to the cardboard.
In this photo I've glued the gussets to the main roof diagonal supports.
Previously, I had been working on the oven itself. In this photo you can see the Seuthe smoke unit (anemic!) and the 2 mini-fans designed to push smoke out the Charging doors. The view is towards the front of the oven. I've since ordered an MTH smoke unit for this mission.
More when I know it.

That must be the N scale smoke unit??  |

That must be the N scale smoke unit?? Uh, no. Why do you ask?
It's a Seuthe No. 7 that is designed to fit inside O gauge smoke stacks or in a building. It runs on 11-16 Volts (AC or DC).
And unfortunately, it's not up to the task. I'm going to try an MTH smoke unit in its place. This is the effect I'm trying to achieve.

The smoke, now that's going to be quite an accomplishment.

Seriously, thank you. I hope so. Pulling it off is going to be a challenge.

Even though it should be big enough, it only puts out enough smoke for N scale... My attempt at scale humor.
