Power Plant Modules

Metrolina Model Railroaders are currently working hard on a new double-size Power Plant Module which consist of 2 8′ long modules. Visitors to the North Carolina Transportation Museum during the summer of 2024 can view the ongoing construction of the Power Plant modules as we continue to build them.

Progress of Work

  • 2024-07-25: Rick informs Henry that more plaster cloth has arrived.
  • 2024-07-22: Information, History, and Updates posted on the MMRR website about the Power Plant Modules.
    • Henry emails responses to Joe and Bradley.
  • 2024-07-20: Scenery work session #2 at the NCTM.
    • Gordy and Henry put down the foundations of a highway across the back of the 2 Power Plant Modules.
    • A combination of different types of Styrofoam were applied to the top of the plywood.
    • In some places, brown paper, newspaper, and paper towels were used as filler and underlying ground / road formations.
    • Woodland Scenics Plastercloth was applied to the right-side module (as viewed from the back) with the Turnouts Control Panel (TCP) on it to form the roadway and portions of a mountain near the control panel.
    • The removable Styrofoam Mountain used to conceal the wires and the back of the control panel was covered with plastercloth on the inside to give it more strength and rigidity.
    • View: Henry’s MMRR Power Plant Modules Google Photos Album. (Note: This album will have the lates photos and videos that I take, and they will appear within this album much sooner than they appear elsewhere on this page.)
    • Input via emails from Joe and Bradley regarding suggestions for scenery and power plant building.
      • Bradley:
        • I would point out that there should be a step up transformer located against the wall of the power plant. They take 3 phase power from the generator bus and step the voltage up to the transmission voltage. Something like a 14kv to either 38kv or even 138kv depending on the system being served. 
        • Then wires leading to the yard with a set of disconnects then breakers then attached to the yard bus.  
        • Prior to the 1950s the step-up transformer would not be one 3 phase unit but 3 single phase transformers. 
        • You should also have a reverse circuit at much lower load capability for plant auxiliaries. Picture the previous step-up transformer circuit but with 3 smaller breakers and transformers. 
      • Joe:
        • Just a reminder we do have some sub stations that can be used for this. I did send Rick some items for boiler rooms and the control room along with instructions for the turbine/condenser installation.
    • Rick brings the Power Plant Building, a previously assembled Substation, 2 new boxes of substation kits, a small fenced-in set of power equipment, the package of used Powerlines, more Styrofoam, and Hydrocal to the NCTM to be used on the new Power Plant Modules.
    • Henry emails proposed vision of scenery for the 2 Power Plant Modules:
      • I have more work to do on the scenery sections of the Power Plant.
      • I cannot remember if we have a power-station / substation kit already.  If we do, it would be nice to have that available if someone can bring it.
      • If the club doesn’t have a substation, I would suggest that we buy 2 of the HO scale Walthers Northern Light & Power Substation kits and use the platform from just 1 of the kits but put the majority of all the equipment from both kits on that 1 platform.  I suggest this because looking at the Duke Energy plant via Google Maps they have a lot of electric equipment in their station at the plant.  It is crammed full of stuff.  I don’t feel that the model is dense enough with equipment.  The part # is: 933-3025 (currently $37.98/each at Walthers.com).
      • Rick said he would bring the Walther’s High-Voltage Transmission Tower packages that I believe I purchased for the club in Asheville earlier this year.  I don’t remember for certain if what I bought was the Walther’s kit as I think we received it without the original box.  Regardless, I can use whatever we have.
      • I asked Rick to bring the Power Plant as well.
      • Alan brought his Rotary Dumper 2 weeks ago, and we sort of have a plan as to where it will be located.  Unless he has already started on it, the dumper needs to be constructed.
      • We need some more denser Styrofoam, like 1/4″ and 1/2″ blue board (actually green)/ construction grade house insulation.  We could use at least 2′ x 1′ of this.
      • I am constructing a mountain face over the removable top that covers the turnout control panel (TCP)
      • I am going to used plastercloth to form the ground and cliff areas of the mountain.
      • If the club has some rock molds, we could use those as well, along with some compound to make the molds.
      • I was going to sketch a hand drawing of what I have planned and share it with you. However, that did not happen. Instead, I have created a digitized representation of the track plan on the Power Plant Modules and marked it up with the intended scenery plan.
      • I reviewed the materials and information provided by Joe which primarily focuses on the building and its interior.
      • I added to that, the ideas that Alan and I discussed 2 weeks ago as well as my suggestions / proposed overall vision of the entire module. [See photo below:]
      • If any club members have additional input, suggestions, or dislikes of anything I proposed, please let me know your thoughts.
  • 2024-07-12: Joe reminds the club via email of the research he previously conducted on the Power Plant module before purchasing and constructing the basic floor structure. (He also provided the next 2 documents shown below:)
    • I included an updated file with the Power Plant drill guide which has a format for the plant with data that should be helpful.
    • I also included the CMR Turbine assembly instructions which tells how to build the 4 turbines and other items.
    • I recently found a box with hardware and a floor with a condensing tank I have that will be needed. The condensing unit will sit below the 2nd floor and establishes the height of that floor. The tabs on the bottom will have to be removed for a flat fit to the base.

  • 2024-07-06: Scenery work session #1 at the NCTM.
    • The removable Styrofoam Mountain is constructed.
    • Walls and a base are carved out of Styrofoam and placed around the Turnouts Control Panel (TCP) on the right-side module (as viewed from the back inside the layout),
    • The removable Styrofoam Mountain is fitted and contoured to fit between the walls and around the TCP to hide the wiring and internal circuitry of the TCP. The fit is good with minimal seams between the walls and mountain.
    • A Powerline Swath is established to rise out the far right-hand side of the right module.
    • The mountain is steep and will have some sharp front-facing clifts.
    • No pictures were taken of the progress of the module on this day (by Henry). [Other club members may have some photos to share.]
    • Alan brought a Walther’s Rotary Dumper kit. He and Henry collaborate on forming ideas for where to place major aspects of the scene, the rotary dumper, and how to intergrate it all together.
    • Plans are made to extend the frontmost track siding on the left-hand module to allow this siding to go through the rotary dumper and have additional storage track for coal cars not being dumped inside the dumper. This plan is the most efficient we could come up with without making changes to track placements on the other module.
    • Alan will build the rotary dumper kit and bring it back when it is ready to be placed on the module.
    • Henry will build a Styrofoam platform to hold the extended track sections and allow the platform to be cut into to house the underground elements of the rotary kit.

Research Materials, Photos, and Videos

The images and materials below were examined to get a better understanding of how a Power Plant looks and operates. The location of natural resources and other objects around a plant and other aspects were all taken into consideration to formulate the proposed vision of scenery for the Power Plant Modules. They also provide information on Rotary Dumpers and the cars that can be dumped by a rotary dumper.

The Power Plant modules were first begun in 2014 (?Needs actual year). During the summer of 2022, we began coming up with some ideas on how to lighten the 2 8′ modules. We cut out a lot of plywood that made the modules tremendously lighter. Now we are using a lot of lightweight materials to build-up and add scenery.

Quite some time ago, Joe did a lot of research on Power Plants. He also constructed the framework for the Power Plant itself. He has purchased most of the components and model pieces that will be used inside and outside of the Power Plant. Additionally, he has headed up the installation of the electronics and wiring of the track pieces and control panel.

Other members have worked diligently on the modules as well. Some, doing the cutting, drilling, and screwing. Track was laid by several members at different times. Joe Todd (JT) airbrushed the tracks to give them a rustic late 1950’s used appearance.

Henry and Alan have come up with a scenic plan and Gordie has helped out a lot to get us started working on the scenery. Mike is the club’s most reliable tree maker and will be planting his special custom-made trees before the summer is over. Bradley has provided us with his Power Plant management input as to the correct type of transformers that should be in the building and the right equipment outside the building leading up to the substation. Rick’s tools and model building experience is invaluable as he crafts the exterior to the Power Plant.

Lots of members are busy testing the modules during train running sessions on the weekends that we operate the layout.

There are many contributions that I have not mentioned yet. More details to come accompanied by photos and videos of the work in progress as well as some shots over the years (hopefully).

We tried to get Duke Energy to grant us an inside tour of one of their nearby steam powered electric generating plants. However, even though we were told this might happen, it hasn’t happened in the past 8 years. So, we are moving forward without their direct influence.
