Summer Challenge 2026

Not the most exciting title, I know, but I'm working on it.  

The most recent Walthers Flyer included this year's National Model Railroad Build Off contest details.  As usual, there's a freelance diorama category.  In this category the modeler builds a large diorama that can feature any subject, in any scale, as long as it isn't part of an existing layout and fits the 2'x4' size limit.

I have no intention of entering this year and yet, the idea still appeals to me.  When I entered in 2022 and 2023 I really enjoyed the four months of focused work that resulted in a finished scene, from soup to nuts.  It puts pay to the tired trope that a layout is never finished!  When I entered in 2022 I knew we'd be moving soon and the layout work would be put on hold indefinitely.  Before then I had been building real momentum working on the layout which I have yet to recapture since.  It is time to get that back and make significant layout progress again.

So here's the plan.  

I'm going to complete approximately 8 contiguous square feet of my layout instead of creating a diorama for the NMRBO.  From June 1st to the October 1st deadline I'm going to build all the scenery, structures, trackwork and details in that area.  This is the same time period entrants in the contest will be following.  Here's the area outlined in red with salient features added:

The red zone includes structures, sidewalks, street track and an orange grove

If you've been following the blog recently you may notice that the Ensminger Building is already (nearly) complete - this would disqualify me from the Walthers contest were I using it on a standalone diorama.  Note also that the area isn't a rectangle.  This delineation makes the most sense for the content of the space while loosely keeping to the 8 square foot area.

I'm going to start with the street and sidewalks, including the streetcar track since it is part and parcel of the roadway.  The sidewalks need to go in before the structures, though I can work on the buildings at any time and probably will.  In previous challenges I've kept two or three work stations full, shifting from one to the other as necessary.

Here's the caveat: if I don't complete the area fully, that's fine.  I'd rather err on the side of quality and produce a result I'm pleased with than rush something just for the sake of an arbitrary timeline.  However, I accept that "letting the perfect stand in the way of the good" doesn't help and is a trap I've fallen into before.  An imperfect model completed will always bring more satisfaction than a perfect model delayed indefinitely.  That's a significant aspect of this challenge I take to heart.

If you can think up a better name for what I'm doing than "Summer Challenge 2026" please comment below.  Also, if you've got 8 square feet of layout that needs completing and would like to join in, let me know.  I'll be sharing my progress here on the blog and on Instagram.  Before that, however, I've got to complete a couple overdue projects and clear off the workbench.  Thanks for reading.

Diorama Design and Composition

I'm not a professional artist with training or any formal education in the subject, but I know what I like.  That is to say, I have an idea of what a scene could be or might be before I begin building it, and I learn whether or not I like that idea as I build the scene.  As various elements like buildings or major land forms or trees are brought to the space the idea might shift and change.  That was certainly the case with my Walthers National Model Railroad Build Off 2022 diorama.

At first I wasn't even going to enter the contest simply because I was already building a railroad and had a good head of steam and didn't want to lose momentum on that project.  But when I figured I could build a diorama using elements that would find a home on the railroad, and potentially win a little cash to fund the hobby, well, it wasn't hard to commit to the endeavor.  So I set about I making a few sketches of a scene that might easily incorporate models I knew I'd want on the railroad that I already had on hand.  I chose the structures based on how long it might take to build them the way I like them considering the four month time frame of the contest.

Once the structures were selected I could consider their arrangement.  I've always liked intersections and streets, especially the way they relate to the structures alongside them and the way they fit into or shape the natural setting.  Add a railroad to the mix and it gets really interesting.  In this case I decided to keep the freight railroad element to a minimum - a spur for the mill - while giving more emphasis to the horse-drawn street railway, a unique element less commonly modeled.  I considered running streets and tracks parallel to the diorama edges at first, but migrated toward an offset angled configuration to allow more room to develop the grounds of each structure and set it in its context.

The "quadrants" of the scene, defined by the major streets, are not evenly balanced yet the structures and scenic elements give them appropriate weight.  The large Purina building occupies a smaller area than the two smaller structures diagonally opposite.  Think of a beam scale, how the smaller weight slides along a long bar to balance the heavy weight on the other side.

Elements like the farm field, the orange grove, the family garden behind the cottage or the Florida scrub habitat could all be modeled in part along the diorama edge and the angled orientation would give the impression they continued on beyond the edge of the diorama.  A parallel orientation might give the idea that the field or grove ended at the edge.  We assume the streets continue even when perpendicular or parallel to the edge because that's a more commonly seen trope on many model railroads.  Still, I believe even they benefit from the angled treatment.   

Structure roof-lines were also considered in the composition of the scene.  Strong parallel lines like rails running down the brick street give the eye a path to follow.  Other elements interrupt that flow while some reinforce it.  Roof lines can do either or both.  Natural elements like the orange grove can be parallel to the street and reinforce the motion while creating rhythm.  The dirt road breaks the rhythm and lets the eye jump across the street to a different area.  The billboard is set at an angle to the road and is the only man-made element oriented that way; the rest are parallel or perpendicular to each other.

 

Note the color, texture, and the way the elements interact with the edge.  We know that driveway keeps going and turns toward the back porch.  So too the lawn and garden continue.  The strong roof lines direct the eye through the scene and the colors of the house both reflect the tans and reds of the scenery.

Color was a major element considered in the composition.  The bold patterns and patriotic colors of the Purina Mill really stand out against the greens and browns of the landscape.  So too the white billboard.  Across the street, however, the colors are more subdued.  Yes, the fruit stand is garish, but the yellow, orange and green are echoes of the orange grove.  The colors for the Queen Anne style cottage were chosen from actual home colors used in the period.  The maroon and tan on the cottage echo the brick street and sandy soil.

Perhaps the most important color on the diorama was the street itself.  I chose a dark brick color with blue tones to simulate the over-fired bricks used on streets in Florida from that period.  The tan earth of the sandy dirt roads and driveways contrasts with the brick, as does the bright green grass.  I found several photos showing the sand blown onto the road and wanted to highlight this effect.  The other major color consideration was the foliage, from the faded lime green of the palm fronds to the deep dark green of the orange trees and every shade in between.  Florida is a green, lush place, and the foliage needed to reflect that vibrancy.

 

From the muted dark green of the Oak behind the cottage to the vibrant bright spring green of the lawn, I hoped to capture some of Florida's lush and diverse foliage, both in color and texture.  Look closely and you'll spot the Azalea in bloom.  Liriope lines the front path.

  

The final element I considered in the composition was the placement of figures and mini-scenes.  That topic will get a post of its own.  Thanks for reading and feel free to comment or ask questions.  I hope these ideas help you create interesting scene compositions on your dioramas or model railroads.

Lessons Learned

In this post I'll share a few lessons I learned from building a diorama for the Walthers National Model Railroad Build Off contest.  While building a diorama may seem like a simple, straight forward thing to do, it really challenged me to think differently.  The process also made me realize a few things about myself and my approach to the hobby; beliefs I had held but never clarified into solid ideas. 

This is a BIG image if you'll click on it, then open the picture in a new tab for the full size.

First off, this diorama taught me that I could fully scenic a 2'x4' space in only four months, from ground cover to scratchbuilt trees, four feet of brick street, two feet of hand-laid track, three craftsman structure kits, a kitbashed structure, a Jordan vehicle, a kitbashed streetcar and numerous figures, all hand painted.  My current model railroad is only 4'x6' - that's just three times the area of the diorama.  Plus, the Purina Mill, Strickland's store, streetcar, billboard and orange grove all have spots already marked out on the railroad once I decommission this diorama.  If I were to work at half the pace I did to get this diorama done, I could have the Pine Branch Park railroad scenicked in two years or less, to a very high standard of detail and realism.*

Four feet wide

In this contest the focus was strictly on two parameters as defined by the rules; creativity and skill.  I set out to tell a story about a place in central Florida in 1914.  My model railroad has a similar goal, but is set in the late 1920s and includes operating trains as part of the storytelling.  Both use creativity and skill, but the diorama is a more limited setting.  Instead of operating the trains to provide action that tells the story, the setting itself has to do that task.

Why is this man sleeping behind this sign?  Some stories raise questions.

In truth our models, apart from the ones that move, all face the same challenge; how to imply action without motion.  While building my horse-drawn streetcar I realized one possible reason for why more folks don't model this mode of transport; it can't be made to move realistically.  A powered streetcar pushing a lifeless horse down the street would look odd, yes?  Some modelers don't like to use figures that are in an "action" pose, as if time is frozen, because it looks strange next to a train that does move.  On a diorama with no moving trains this matters less, if at all.

Is this a train?

Another challenge I faced was whether or not to use a backdrop.  Modules or home layouts often include a backdrop and the Walthers contest did not require one.  However, the contest submission form called for photos of the "front", "left" and "right" sides of the diorama.  Oh.  I hadn't considered front or back, left or right when planning the scenes.  It was a diorama to be viewed from any angle, and engaged with by the viewer from any direction.  This arrangement made it difficult for me to designate a "front" of the diorama. 

You can't see this from the front.

As someone with an "island" style railroad (see more about that here) I've always built structures with an eye to how they'll look when viewed from all sides.  On a layout where the views are controlled structures and other scenic elements can be built to take advantage of that, omitting back walls for example, or only detailing what will be seen.  On my diorama different views and vistas would open or close as the viewer moved around the scene.  This is how I had begun to imagine the elements on my layout so naturally it is how I placed these elements on the diorama and why all sides received some level of detail as appropriate for the scene.

Did my design choices hurt my chance of winning the contest?  Perhaps.  Most of the entries that made the final cut were pretty clearly arranged with a defined front and back, though not all.  What about the railroad elements?  None were required for the contest, technically, though a train did need to be shown in the final photos.  I think a horse-drawn streetcar is a train and though I had no freight car on my spur at the feed mill, one of the finalist entries showed no train at all.  And the era?  Or locale?  Perhaps.  Very few folks model Florida and nobody I've seen models Florida in the teens or twenties.  This is new territory in our hobby, and sometimes the familiar scene will win out over the unfamiliar.

Figure provided for scale. ;)

Would I do it differently if I were to enter again?  Maybe...or maybe not.  My design choices were deliberate even though I wasn't fully conscious of all the assumptions influencing my choices.  A viewer can't see it all from any one angle, just like real life.  It tells a story through the composition of elements and placement of details.  The setting is unique and hasn't really been explored before.  It demonstrates skill and creativity.  But most of all I'm happy with the diorama I built - it makes me smile whenever I look at it.

*Completing the current model railroad will likely take longer than two years.  As of this writing I'm still unpacking boxes and sorting my garage, and won't be doing any more work on the railroad in situ until I know the roof won't leak and rats won't be chewing the scenery.  I'll be following Bruce and Janet Chubb's example from their early modeling days, building models at the kitchen table until the train room is ready.

Sub-Roadbed for Streets, Ditches and More

I decided to use cork sheets for the base of the streets in Ocala Springs, aka Pine Branch Park.  The wider road uses 3/16" thick material while the narrower road uses 1/8".  Note the cork is cut wider than the road surface to include the sidewalks, shown here in their raw, gray resin state.  These are herringbone station platforms from Frenchman River which I will cut and modify as needed.

Speaking of station platforms, I will also be using a herringbone brick pattern there but this one is laser-cut material by RS Laser Kits.  The base under the station platform and parking area is 1/4" cork and will be slightly sanded and shaped before the area is scenicked more fully.  The plan for this and the streets in general is to use spackle, though that may change as I consider other options.  There's more to be done before that step.

That gouged-out mess in the second photo is going to be a drainage ditch.  Drainage is THE most important element of track laying on the prototype.  Here I used a Dremel with a cutter attachment to rout away the press-board sub-roadbed surface.  Once contoured and scenicked it will not be so ragged.  Pipes will be used at the track to convey the water away.  Not sure yet what kind of pipe I'll use.

I also painted the track using Espresso - not the coffee, the paint color by Rustoleum.  I like their UltraCover Paint + Primer.  It claims to cover wood, metal, plastic and more; ideal for track.  The finish should be 'Satin', but appears glossier than that to my eye.  That's okay, as it will be dulled down with further color applications.  Ties will be painted with various shades of brown and gray, then washed and dry-brushed, before rail and tie plates receive a coat of rust color and grime.  I may take one section all the way through ballasting to see how it looks.  We'll see.

Scenic Start

With the tombstone project out of the way until warmer weather arrives, I turned my attention back to the railroad.  The paper mache' clay I use for the stones is very similar to Sculptamold or Celluclay.  Not wanting to waste it, I decided to install the terrain along the creek.  The leftover clay is wrapped in two layers of plastic wrap in the first picture.  By this time it is a few weeks old, going on a month.  With the no-flour recipe I use there's very little to mold or turn sour.  Not sure how long it would stay workable but I didn't use it all on this project so I've wrapped up the rest and will check periodically to see how it looks.  Anyway, I used a block of floral foam as a substrate and applied the clay over that.  It takes a while to harden but I'm in no hurry.  Once it is good and dry I'll rout out the bottom of the creek a little deeper before applying additional texture.

Red + Yellow =

I need an orange grove in this spot.  Maybe, just maybe, one morning I'll come out to the garage and find it.  Magical plastic cross-pollination?  These days I think anything is possible.  Who knows?
