No, it’s not done. Just mocking it up for fitment. 
Enjoy!

Adding Guard Rails to the Helix
As you may or may not know, I have a helix to connect the upper and lower decks of my Georgetown Branch layout. I built the helix ages ago, back in 2003 for my previous layout. It was designed to fit below a set of stairs and as such is relatively tight, with 19.5″ radius curves and a 2.9% grade. (yikes!) Thankfully I mostly run small B+B locomotives! One thing that is lacking is any sort of protection for the trains as they traverse the helix from falling off the edge and cascading to the floor. I thought about cardboard or mat board strips but decided against them as I didn’t like the idea that they would crease or break if I had to reach in to re-rail a train. I have been kicking this idea around for ages and recently had the idea of using polypropylene folders. These are the flexible-yet-stiff plastic folders you find in a lot of school binders. When I was cleaning out a supply cabinet, I found a stash of old folders from my son’s grade school days. Perfect. So I got around to testing this out.
I first remove the inner folder piece (seen in the photo above as a lighter green) and then set the edge of the folder against a sheet of glass and lay my steel ruler down atop it. I then score until the sheet is cut through.
Next, lay the strips on the side of the roadbed, keeping it parallel to the bottom, and use a staple gun to fasten to the plywood.
Some of the staples will not go in all the way and I tapped them in with a hammer. Occasionally I would miss and have to remove the staple with a screwdriver and try again. I really like the way this is turning out.
Constructing a Paint Rack from MDF
I was gifted some shelving my Grandfather had built for his house on Cape Cod many years ago. It once sat in the laundry room and held baby food jars full of nuts and bolts as well as small jars of oil and other knick-knacks. When the house was being closed up, I had asked for it since I knew it would make a wonderful paint storage rack and currently I was just using a few odd cardboard boxes. Well, over the years I have outgrown that little set of shelves and finally decided to construct some new ones, this time using MDF.
This project took about a half day, as it took a good bit of ripping and fitting to get everything right. The back and shelves themselves are 1/4″ MDF and the sides are 3/4″ MDF. I used a dado blade set to cut grooves in the sides for shelves and to recess the back panel. In retrospect, I could have recessed it a bit more and could have fit the shelves a bit tighter, but it all worked out just fine in the end. The back was glued and tacked on with nails. Shelves are glued in place. I hand painted it two coats of semi-gloss white, some paint I had leftover in the garage. The fact that the paint is a bit “tacky” means the paint jars don’t slide around on the shelves. The whole thing sits on a rail that’s screwed to the wall, with L-brackets up top screwed into the studs. I modeled it after the shelves my Grandfather built with shelves set to accommodate the various paint bottles I have collected. Overall, I think it’s just right for what I need and it turned out well.
Workbench Update: 9/4/22 Rock Creek Trestle
The last several weeks proved to be some of the busiest for me at work and as such progress has slowed. Today, however, I tackled another milestone – completing all of the assembly for the trestle structure itself. I tacked on the final bracing, stringers and girts to complete the lower section. Here’s a few photos of what it’s looking like:
This means that the to-do list is getting shorter and shorter. Here are a few highlights of what’s left:
- NBW castings on the side-facing stringers and beams. This will take a good amount of time as I will have to drill and install each one. Much like what I did on the bents, but a bit fewer. I’m not going to install NBW castings on the inner facing beams due to the difficulty in placing them in such tight spaces.
- Attach a brace to the bottom of the middle two bents. This will serve as support when the model is turned upright.
- Build a sort of cradle to hold the bridge when upright.
- Remove bridge from base and flip upright onto cradle/steps.
- Build two emergency platforms on the top side.
- Install the two beams that run atop the deck parallel to the track, install NBW castings.
- Install bracing/walkways that run along top of bents.
- Weather and install on layout.
- Build and install bracing around lower center bents and cribbing for the ends.
- Drink a cold beer.
Workbench Update: 7/17/22 Rock Creek Trestle
Exactly one month since my last update and I’ve made some great progress on the Rock Creek trestle model that I’d like to share.
On Friday I built a sled/jig thing to facilitate installing the bents perpendicular and square. More on this in a moment. First up, I needed to flip the top of the bridge over, as it was mounted with track side up. I then took the opportunity to extend the lines that indicated where the bents would be installed, as this would guide my sled/jig later. I also measured where I wanted the straight edge to be and installed it with double-sided tape.
Next it was time to install the center deck girder section (which I had previously built, painted, weathered and installed ties and tie plates). I prepared some 5-min epoxy and lightly brushed it to the back side of the rails. I carefully positioned the bridge in place and weighed it down while the glue dried.
I then completed the blocking around the deck girder.
The sled/jig allowed for me to install the bents perpendicular and square to the base. This took a bit of finagling to get set up properly but made the job go fast once the system was in place.
Halfway there!
And here we are with the completed bents. It’s looking pretty good!
If you flip over the photo you can sort of get a feel for what the completed model will look like.
Ok – that’s all for now. I’m very pleased with how this is coming along and up next I’ll be installing all of the stringers and girts to get this over the finish line! Stay tuned…
E.C. Keys Coal & Fuel Oil Trestle Model Project

(NOTE: UPDATED DRAWING TO v2 BELOW 7/3/2022) Just about a hundred yards west of Georgetown Junction was the Enos C. Keys & Sons company that sold building materials, aggregates, merchandise, coal and fuel oil from 1889 until 1978 when it finally went out of business. On the North side of the Georgetown Branch track, a turnout branched off and climbed up a steep embankment and sat atop a high retaining wall where it served a warehouse for building materials. Aggregates would be unloaded over the side of the retaining wall via chutes, down into large sorting bins below. On the south side of the GB tracks, a turnout diverged, rose slightly, and then out on a coal trestle that was approximately 227′ long (based on aerial images). This trestle also served as an unloading platform for fuel oil. In the very far northwest corner of the property, at the intersection of Brookville Rd & Stewart Av was the scale house, which was torn down recently. In a strange twist of fate, a fellow GB-served industry, T.W. Perry, is now occupying the E.C. Keys space atop the retaining wall. The lower area where the coal dock was is now a long warehouse building. Much of this will likely (or already has) change once the Purple Line construction is completed.

For my model railroad, I am modeling the coal trestle, retaining wall and siding, and the long lumber warehouse.
I decided to spend some time studying the site and develop a plan for my model of the trestle.
Using the scale tools available on the Historic Aerials site I was able to get basic measurements of the trestle. Approximately 227′ long, 15′ wide, bents (bins) about 15′ apart. This was enough to get me going, along with other details in the coal yard that I could observe. I now needed to figure out what sort of prototype to go after. Of course, without a photo I have no idea what the design of this trestle was derived from, but a good starting place was with the B&O Standard Plans book. I happened to have one that covers such things:
This fantastic reference book is available through the B&ORRHS Company Store, now in digital format. I highly recommend it! After some mocking up on my model railroad I realized that I wouldn’t be able to model a whole 227′ trestle and needed to reduce the size. I settled on a nice 135′ which will allow three 40′ cars, two less than the prototype would have held. This would work nicely for my small layout and even at this small size would still be a formidable structure. (I sure am building a lot of trestles on this layout… sheesh. I’ve got about four more to go, but that’s for another day!)
So, using Adobe Illustrator, the B&O plans and some photos I found online of similar structures & models, here is what I came up with:
So the image is quite wide – click for a larger view. I hope this gives you an idea of the design I’m after. I tried to stick as close as possible to the B&O design, but added a few modifications that I felt were necessary. One was the inclusion of additional supports for the walkway, a wider walkway, along with a railing. I also made some slight height adjustments but stayed within the requirements laid out in the B&O plan. All in all, I think it’s a good representation of the trestle and will make a very nice model. If you’d like a copy of the vector file, it’s below as a PDF for your own personal use. (NOTE: UPDATED to V2 7/3/2022)
The E.C. Keys facility will be a key scene on my layout. It’s a fascinating area to switch and this coal trestle will be a centerpiece of the small industrial area. Now to finish the Rock Creek trestle so I can get on with building this!
Workbench Update: Rock Creek Trestle Status
I know, I know, the trestle has been moving forward at the speed of slow. It’s been a while since I made an update so I figured I’d put a stake in the ground and share where I’m at.
Last Tuesday during my train club “Bench Time” I finished the last of the 20 trestle bents. Yesterday evening I touched up any of the unstained ends of wood that I missed and installed a few NBW castings that I missed. They are done! I consider this a big milestone. On to the next step.
I spent some time cleaning up the trestle deck and clearing space for assembly. My plan here is to build a sort of sled with a flat vertical face to lay the trestle bents against for installation. I will keep it square by mounting a straight edge along one side that the sled can slide against. More on this in a future post.
Finally, I laid the side view schematic out on some 2″ foam core and began to cut the various stringers, girts and braces that will go on the trestle sides. I need to cut, sort, prep and arrange all of these pieces before I can begin to install the trestle bents to the top deck. I have this weekend off so I think I will try to make more progress.
The project is coming along nicely. The last several months have been busy and as such this fun project has been going slowly. I have mainly assembled trestle bents during train club Zoom meetings. One or two a night, every week or so. I’ve also been working on a few other projects. I’m good at starting projects; bad at finishing them. Can you tell?
What’s On The Workbench
It’s a rainy, wet, dreary day here in Maryland; AKA perfect model railroad weather. Decided to put a kit together today so I’m digging into this old Branchline 50′ B&O M-61 boxcar kit. 
Edit: and, done:
New Video: How I Install NBW Castings on my Rock Creek Trestle Model
I put together a short video on how I am installing Nut-Bolt-Washer (NBW) castings on my model of the Rock Creek Trestle. Hope you enjoy it!
Quick Update: Layout Visit Projects, and More
I know I haven’t posted in a while but as the Spring approaches, things are getting busy around here. Work has been nuts. HPDE season is upon us and I’ve got my first event at Summit Point with the Audi Club this coming weekend. Track prep time! Here’s the update:
Layout progress has been focused on cleaning up, organizing and working on the Rock Creek trestle, as well as devoting a large amount of time to working out the operations scheme in JMRI Operations Pro, with lots of help from Kelly R. The cleaning and organization tasks were accelerated by a visit from Ken & Bill from Spring Mills Depot. Ken and I chatted at the Springfield show and decided to get together to see each others’ layouts and share progress and lessons learned. It’s been very motivational seeing what Ken is doing and having them visit my layout to talk about my own process and future goals. I’ve got lots of good energy to move forward with.
Coupled with the layout visitors, I have also been selling a lot of extra stuff on eBay. Over the last year or so I’ve really culled a lot of rolling stock and material from my collection. Much of it was sold at the GSMTS Timonium show, but much of it has been sold via eBay. As I clean and dig through my things, I find more and more to list for sale which really helps motivate me to continue to refine my focus and standards for the layout. Also, the sales help pay for the layout materials and new freight cars that I come across. Here’s a photo of the layout from a month or so ago:
JMRI progress has been a real roller coaster. Yesterday morning, in a fit of frustration, I was ready to swear off the program (both literally and figuratively) after running up against a string of constant, baffling errors. Kelly talked me off the ledge and offered to help rebuild and refine my layout concept in the software. I’ve realized that JMRI is going to be the best solution for what I want to do with the operations scheme on my layout; it offers pretty much all that I want, even though I have a long way to go before I get to my goal. I do have a document which outlines all of my “givens & druthers” as well as rules, specs and other details about my scheme. This will be published later for anyone who’s interested. Also, if anyone wants to talk Operations or JMRI, please reach out! I’m neck-deep.
A byproduct of the layout visitors and the JMRI work I’ve been doing was that I put together manifests for four trains that I refer to as the “Bethesda Turn”, since Bethesda is as far as the track currently goes on my layout. After the visit, I ran these four trains as I intend to run most of my trains, and it was fantastic. Yeah, not all the switch machines are in place, and some of the frogs aren’t wired, but the overall feeling of what it will be like to operate the layout was there, and it was really cool. A taste of things to come.
I find that in this hobby it’s important to have active projects in different areas of the hobby to keep things interesting. Last month when I got tired of installing DCC decoders and building trestle bents I switched over to building a freight car kit. The one I chose from my shelf-o-unbuilt-kits was an old Intermountain PS-1 50′ Double Door Box Car lettered for Southern Pacific #650159, kit #40607-10, with a 1955 build date; just inside my era. I found this kit on the shelf at the Annapolis area LHS, Star Hobby, for a had-to-have-it price of $10. Side note: I-M seems to be taking reservations for a re-release of this kit right now!
I hadn’t put together a challenging kit like this in many years and I had a blast. I upgraded it with a Kadee Apex running board, some Tichy end grabs and Tangent ASF A-3 wheel sets. (The prototype apparently had Symington-Gould A-3 trucks, but I haven’t found a manufacturer for those in HO.) The kit didn’t come with instructions, but thankfully I found some on the I-M website. It’s really nice they put the instruction manuals up on their site!
Car weights came in the form of wheel weights I collect off the ground at track day events, which I glued to the interior floor with Liquid Nails. The body was badly warped at the top and required careful attention to straighten when gluing to the roof. The doors were also ever-so-slightly warped but once in place looked fine. All in all, a neat car. I don’t have many 50′ cars so this one will look nice delivering lumber to Galliher Lumber in Georgetown.
Lastly, a word about the NMRA Achievement Program (AP). Over the winter I was inspired to begin participation in the various AP areas. A few of the folks in my club are diving in and working toward their MMR so I figured I’d join the journey. So far, not a whole lot of movement on my end. I’ve started organizing and reading through the materials but that’s about it for now. I just haven’t been making this a priority, as I’ve had other things going on requiring attention. However, I have been taking photos of some of my projects in preparation for writing up articles. I will definitely post links here once that materializes. For now, I’ll keep planning and aligning my modeling efforts with the various AP certification qualifications. I think of it like merit badges for adult model railroaders. I’m enjoying the challenge!
Like I said, this is just a quick, off the top of my head update. I am hoping to be able to post more, but with work being so busy and other things vying for my time, I do what I can when I can. Be well and keep in touch!
