The Ridgway Roundhouse
April 2, 2025
The Ridgway turntable and future location of the roundhouse are right inside the door as you enter or leave the layout room. The turntable was installed more than a year ago and the drive was installed back in July of last year (Construction Update #36). As a result, the thought occurred to me that the roundhouse might be a nice addition to the list of ongoing projects.
My original plan was to purchase a Banta kit and modify it to fit the space; a bad plan. Ultimately I decided against sacrificing a $350 kit for in order to build an questionable, at best, representation of the prototype. Instead I decided to scratch build the model, to fit the available space, from styrene, strip wood and laser cut brick sheets from Monster Model Works (for the visible exterior walls). For the interior, my "stash" included a package of brick wall paper texture sheets from Paper Creek Model Works.
The first step was to draw a floor plan. Due to my limited space I initially planned on reducing the depth of the stalls from 72 to 65 scale feet. While shorter than the prototype, the 65 feet would still accommodate a K-27. Unfortunately, the resulting doorways were only 10 scale feet wide instead of the required 12 feet. Since there wasn't room to move the roundhouse further away from the turntable, the only other option was to increase the angle of the radiating tracks and rework the two turntable lead tracks. Again, there wasn't really room to make those changes. Ultimately I decided to reduce the length of stalls by another 6 scale feet which allowed me to move the roundhouse further away from the turntable and accommodate the 12 scale foot wide roundhouse doors. With the exception of the K-27's all my other RGS power will squeeze within the shortened stalls.
The Plan
I decided to start with the framing. There are plans for the Ridgway roundhouse in the RGS Story, Volume I. I took a picture of the plans and loaded the resulting images into Photoshop. Then, using the "Transform" tool, adjustments were made to fit my space. This is probably about as close to the prototype as the model will ever get!

Since I needed more than one section of framing, I decided to build a fixture out of styrene so they would all be exactly the same. Several subtle changes were made during this process. to include a minor adjustment to the length of stalls to add a little more depth. The components were cut using the fixture. They were then removed for staining, allowed to dry and placed back in fixture for gluing.
Here is the framing.

The cores for the side walls were cut from .030" styrene. The Monster Model Works "Old Bricks" will be laminated to the outside of the walls, Paper Creek "Brick Wall" will be used for the insides.
The Paper Creek brick was attached with double sided tape. Since the roof trusses would probably sit directly on top of the bricks side walls/pillasters, the timber roofs supports next to the wall may or may not be correct. The windows came from my "left overs". Since I only had one package of windows, windows weren't used on the side wall facing the backdrop
The Cut Between Placerville & Wilson
April 9, 2025
While waiting for the Monster Model Works laser cut brick sheets, I did some work on "new" rock face between Placerville and Wilson. The pink foam rock face was given a coat of earth colored flat acrylic exterior house paint and allowed to dry. Several earth tones and black were then sprayed on to the rock. The sprays were made by mixing acrylic paint pigments, water and alcohol.
The end result.

The "Old Brick Sheet" materials arrived! If you haven't built one of the Monster Model Works structure kits or tried out their laser cut building materials you should. The texture is amazing and it is very easy to work with. Also received engine house stack set from Grandt Line (ebay).

The inside of the left wall.
The inside of the right side wall. Since this wall and the back wall will be facing the backdrop and can't be seen, the pilaster was left off one end (left).
The far side of the back wall. This wall will end up being about 5 inches away from the backdrop.

With the roundhouse walls ready to finish, several tests were run to figure out how to model the brick walls. I started by sealing the laser cut material with Tamiya TS80 Flat. Then three mortar colors were applied left to right; Ceramcoat Light Ivory and Quaker Gray and Folk Art Linen. The mortar colors were allowed to cure overnight and another coat of flat was applied. I decided to use the Quaker Gray on the model.
The wall was given a generous application of Quaker Gray in order to make sure all the recessed mortar lines were covered followed by another coat of Tamiya flat. A
sponge, with very little paint, was then used to dab on the brick
colors; Americana Heritage Brick, Mississippi Mud, Napa Red, Soft Black,
Folk Art Bark Brown and Raw Sienna and Ceramcoat Barn Red.
There is no need to clean or replace the sponge during this process. I generally worked light to dark and used a sheet of paper to remove about 95% of the paint before I started dabbing it on.
The finished wall. The lintels were cut to size, painted and glued to the wall with Aleen's Tacky Glue.
The Sn3 Symposium
April 22-26, 2024
Work on the roundhouse got interrupted by the Sn3 Symposium in Salt Lake Center. The annual event was hosted by Chairman Doug Jolley and Co-Chairmen Gil Bennet and Mark Evans. They did a fantastic job! I attended with a group of modelers from here in the Pacific Northwest and I think I can speak for all of them in that we can't wait until next year when the Symposium will take place in Denver.
The Symposium included clinics, layout tours, op sessions, vendors, model contests, a swap meet, and plenty of time to meet up with old friends. There were about 130 attendees. The high point for me was operating on Doug Jolley's fabulous Sn3 3rd Division layout. Here is a picture of the coal train I was assigned to operate. It just happened to be powered by one of my favorite narrow gauge locomotives, a C-21. And I actually made it across the division without being written up by the superintendent.
There were about 12 layouts open for the Symposium. Unfortunately, I didn't get to see all of them. One I did get to see was Steve Blodgett's HO standard gauge Bear River Railroad. You don't seem many 1880's era layouts but this one is pretty special. Steve's layout features beautiful scenery, fabulous scratch built structures and smooth running period locomotives.
When it came to the vendor sale and swap meet there were only two things on my want list. I have been in the market for a P-B-L RGS 4-6-0 #22 or #25 for some time. Unfortunately I didn't find one. I did, on the other hand, bid and win a Sn3 P-B-L brass CONOCO tank on ebay while I was at the Symposium.
We also took a trip down to Promontory Point while we were there. While the visitors center was closed and the locomotives were shut down on the day were were there, we did get a short tour of the engine house which was very interesting.
