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.

Even though it should be big enough, it only puts out enough smoke for N scale... My attempt at scale humor.  Unfortunately you are correct. Actually, that's a great way to describe it. It's replacement, an MTH unit, just arrived today in the mail. Haven't hooked it up yet, but I expect a much better outcome.

Updated 1/23/2022:
Sometimes with reflection comes clarity (not always). I have been wrestling with some aspects of the Weirton Steel Open Hearth mill. In particular, I have been debating changing its size (it’s gotten both bigger and smaller) over the past 2 weeks. The building will have at least 3 smoke units and they need to be reachable for service. Tracks inside and near the structure also have to be accessible in case of derailments or other problems. And I wasn’t comfortable with the placement of some auxiliary structures.
Here's the "before" track plan.
And here's the "after" track plan. 
So after much thinking, here are the changes and decisions: - The Open Hearth has changed from 60” in length to 52” long. Mill width has gone from 36” to 38”, with the 2 extra inches going to the “Lean-To” portion that houses the smoke stacks, electronic circuitry, and power supply.
- The entire mill will sit on a single piece of 5/8” plywood. This will make it easier to transport.
- The number of smoke stacks has increased from 3 to 4. Two are dummies.
- The size of each furnace in the interior has gone from 20” to 11”. There will be 4 (Nos. 14, 13, 12, and 11) versus 2.
- The section of the main roof between furnaces 14 and 13 will be removable (for service).
- The entire front of the building and the protruding Cinder Yard will be one piece and removable so that visitors can see into both sides (Pouring Floor and Charging Floor) of the building.
- The number of sidings entering the building will be reduced from 2 to 1. That siding will remain along the northwest edge of the building and serve the Pouring Floor. This results in the elimination of Switch #14.
- The area in front of the mill will be cleared of all auxiliary structures, with the compressed air tank structure moving to the front of the neighboring Strip Steel building. The area in front will become a large access hatch disguised by something (probably a parking lot or truck staging area for the Strip Steel).
- The Strip Steel will become a bit less wide. The building will be used to disguise a large access opening underneath it. This will allow me to reach the side of the Open Hearth and service all smoke units.
- The Strip Steel spur track will be moved down towards the southeast edge of the building. That means moving Switch #18 further east (towards the backdrop).
More when I know it.

You certainly plan well, George. I am so impressed with your detail. Pays off during construction.

Thank you. Measure once, cut twice!? No, wait...LOL

Updated 1/27/2022: No photos, but some progress to report. - Got the repaired power supply back and it's functioning correctly. It drove both MTH smoke units and the Seuthe unit adequately. Amazing what the proper output voltage will do, isn't it?
- I am in the process of revamping my giant Plastruct order (Hint: It ain't getting smaller
 ). None of the stuff I want is available through the shop's regular distribution channels, so they will have to order direct.
- Temperature was -10F this morning. Good to be inside working on a hobby.
- All 9 of the main roof trusses are finished. Hooray!!!! That's 9 x 38 = 342 pieces assembled.
- I'm doing a little research and then will start (maybe) on the OH's Cinder Yard extension (3 half roof trusses).
More when I know it.

Sounds like progress George.

Looks like you solved the power problem, George. Good for you.
-17 yesterday morning. Now that's cold.

Adam, Brian, Joe - thanks for weighing in.
Yeah, the roof trusses were a major milestone. They were difficult and finicky and the jig wasn't as robust as I'd hoped, but we're done with those. I am trying to determine if an extension to the building existed in the era I am modeling. If so, I will build 3 more half-trusses for it. In the meantime, I am moving ahead to the construction of the 4 open hearth furnaces themselves.

Updated 2/3/2022: It wasn't very glamorous or photogenic, but I spent a lot of the day with a calculator, fraction to decimal conversion table, and my Visio program creating 3 view of an open hearth furnace - top, front (charging side), and rear (pouring side). Along with accurate dimensions, I have found some Plastruct "shortcuts" to creating various prototypical appearances. Tomorrow, I hope to start building the first of the furnace fronts & tops. We'll see how that goes, learn from the experience, and then see if we can't apply those lessons to the next 3.

Good luck George. This is not a beginner or even an intermediate level project.

Updated 2/10/2022: - Work continues on the open hearth - sides for all 4 furnaces have now been cut. I hope to cut the pouring floor sides (backs) and regenerative (checker) furnace sides later today.
- The glue sticks I tried for mating brick paper to styrene failed to hold. Per the recommendation of www.thistothat.com, I tried some 3M No. 77 spray adhesive, which appears to be working. The paper was produced by the Evans Design software program Brickyard 3. You just select the proper scale, type of brick or stone, and print to your inkjet.
- Speaking of Evans Design, I had a little design session on the phone with them yesterday. In addition to the oven lights, I ordered several other circuits for various mill animations.
- Over on an O scale yard sale site, I picked up 18 sets (8 each) of rather obscure or old Plastruct theater seats. They look a lot like waiting room seats. That's good, because they are going to serve that purpose for all my 1:48 passengers waiting at the Steubenville PRR station.

They are terrific folks to work with. I use them all of the time. Got a project ready for Dave & Shelly as well.
