Design notes on bases for dioramas and micro-layouts

Base for Moon Mail Madness diorama after Cell-U-Clay had hardened.

I thought I’d spend a little time writing down my thoughts on how bases for dioramas and micro-layouts should be designed; well, maybe I should back off a bit and say these notes are about how I like to design bases. I think about this topic from time-to-time and it popped into my mind again after participating in the recent scale model show held here so I figured maybe this was a good time to put some notes together. I don’t claim any originality or universality here. No doubt many modellers have gone down this road too and touched on many of the same ideas. I can’t say that these notes apply to all situations; your mileage may vary :-)

I used the models to sketch on a big sheet of paper how each would be positioned on the base.

Ok, let’s move on to the first topic. These notes aren’t in any particular order, just what pops into my head as I write.

The arrangement went through several iterations; this one is close to the final

Inspiration: MacRae, Smith, Bennett, Adams, + ...

To me a diorama isn’t just a few objects or figures set on a base to show off a model in a more favourable light as implied by the show’s flyer, which noted that for their purposes we’re looking at a diorama when the following condition is met: “As soon as ANY [JDL: All caps theirs] objects are added to the bases other than the model, it will be classed as a “diorama””. To me a diorama, in the context of scale model work, isn’t simply a collection of objects, but is a model display that tells a story. The story is the primary feature and the models support the telling. A few objects or figures on a base accompanying a model isn’t a diorama, it’s simply a way of displaying a model to best advantage.

From time-to-time eye level views were assessed as the arrangement was iterated.

I’m much inspired by the dioramas of Bruce MacRae, especially his Wine Tasters diorama, as well as the scenes constructed by Michael Paul Smith, Amy Bennett, and Kim Adams. 

Now the work of Smith and Bennett aren’t dioramas in the sense that scale modellers use. Smith created what could be considered temporary scenes for purposes of photographing them, and the temporary scenes Bennett builds are for creating paintings from. However, the key here is they both use models to create scenes that tell stories. 

The objects Kim Adams makes are closer to that of classic model making diorama-ists, but the content of his work is very different. His stories are often ones of exploration into alternative possibilities of our physical world, not just highly detailed reflections of it.

But, the connecting thread running through the work of all four artists is that the centre of interest in their dioramas isn’t one or two particularly well detailed models, but stories. 

Scraps of foam sheet to be used to make the base.

In the model railroading world, E. L. Moore is my main influence. Not everything he built centred on a story, but a lot did. Over the last few years I've been impressed by the layouts shown in the French magazine Voie Libre. Ok, yes, this has an air of shameless self-promotion since a few photos of the Loonar Module appeared there in 2023 in a micro-layout feature, but in my defence I submitted photos there for a couple of reasons. I was impressed by the small layouts they'd written about over the previous 3 or 4 years, and I had never seen a layout set in a Canadian scene by an actual Canadian in their pages! I wanted to fix that injustice :-) The rest is history :-)

I quite enjoy all the layouts Voie Libre has featured, but I especially like the work of Bernard Junk and Detlev Horn, notably their layout called The Island.

Continental Modeller is also a good place to see innovative layouts. And, yes, yes, more shameless self-promotion, the Centennial Experimental Farm layout appeared in its pages this year. 

All I'm saying is that there's a lot of interesting work going on in the wide world of model railroad layouts

Shape: Base Shape Helps Story

The footprints of many dioramas and small layouts are simple geometric shapes: squares, rectangles, circles, and ovals. This is quite understandable as these are readily obtainable in the form of pieces of wood, picture frames, display plaques, and so on. I’ve come to think though that the footprint should help tell the diorama’s story.

Sometimes foam sheets were glued together to make suitably sized pieces

I didn’t really understand this when I built the Loonar Module. I used 2’ x 2’ by 1” thick insulating foam sheets for the base because they were easy to buy at the local home renovation store. But, I wound up building a round island on a square lake! It turned out ok, but if there’s a next time the base’s footprint will reflect the story since water isn’t square :-)

Later, when I was building the Centennial Experimental Farm layout I could have just gone ahead with a rectangular footprint for the base, but I thought it more appropriate for the base to be rectangular at the Carling road end since the road was all straight edges, and rounded at the streetcar return loop at the farm end. There it matched the graceful loop of the track, and didn’t present dead corners to be filled in as it would if this end was also square. So, curved lines at the natural end, and straight edges at the urban end.

A layer ready for cutting out with a hand saw and knife.

The Mt. Lowe layout is where I’ve really started to apply the ’base shape helps story’ principle. Mt. Lowe had several scenes that I wanted to capture, but they had to be somewhat separated from each other. The trefoil seemed to help realize that desire with its three prominent lobes, each providing a separate scenic area. Thinking about the trefoil’s scenic potential a bit more I realized its footprint actually allows for 7 scenes: the 3 lobes, the 3 concavities connecting the lobes, and the aerial view, which in this case is a mountain top observatory.

Lots of scraps and foam dust after cutting out the pieces.

With the Moon Mail Madness diorama I took the principle further. As you can see in this post’s photos I designed the base’s shape as I used the models to sketch out the story; both developed at the same time. And what is the story? It’s a slice of life in the lunar postal service: two lunar postal workers meet at a crossroads and one takes a photo of the other as he begins to remove letters from a mailbox :-) I thought the base’s footprint should match the shape of the road intersection to emphasize the crossing. Also, why make the base square or rectangular and have to deal with dead space that needs filling? The only external limit on the footprint was the show’s specified requirement that all dioramas had to fit in a 2’ x 2’ area, not be a 2’ x 2’ area, which was no problem fulfilling.  

White glue holds the stack together. A rasp and sanding blocks used to form the final shape.

Presence: A Subtle Call to Look

Over the years I’ve come to like thick bases for dioramas and small layouts. 

A lot of dioramas and small layouts I’ve seen present the viewer with a decent top side model and scene set on a thin, platter-like base. Sort of like a meal that has been put on a dinner plate. Some might say, well it’s the modelling that’s of interest and not what it’s sitting on, much like it’s the meal that’s important and not the plate below.

An anti-slip mat was cut and glued to the bottom of the base.

To me though a diorama or layout is a complete, integrated object; a type of three-dimensional sculpture. A diorama doesn’t consist of a good part (the model work) that is to be enjoyed and an irrelevant support part (the base) that is to be ignored. The base’s footprint helps to tell the story, and its height helps to command you to look at that story by establishing the diorama or layout’s physical presence amongst all other objects that vie for a viewer’s attention.

This is another idea that at first I didn’t fully appreciate. The Loonar Module’s base is 3 foam sheets thick because I wanted it to be quite rigid and strong. Mission accomplished. However, looking at the result over weeks and months I felt the thick base gave the layout a solid look that I quite liked. It seemed like the island actually was rooted in something, not just sitting on something.

Anti-slip mat trimmed to fit the bottom of the base.

On the Centennial Experimental Farm I deliberately made the base height about the same as what I thought the tallest tree would be. It seemed odd to me to have big, tall trees (completely to scale regarding height and canopy volume) sticking out of a base no thicker than a pizza box. It didn’t seem balanced. It didn’t seem substantial.

However, like the Loonar Module’s base, I painted it black because I didn’t want the base to draw attention to itself. Its job was simply to say “here’s a story” and bring it to a viewer’s attention, not be the story. The base is to be the strong silent type component in this object we call a diorama: it provides structural support, it’s footprint provides narrative support, it’s height makes a call for attention and visually balances the models, but it tries to do all this in a subtle manner, not calling unnecessary attention to itself. 

The mailbox rise is glued to the base. Note commercial vac-formed crater to the right.

Moon Mail Madness violates the subtly principle a little with the inclusion of the postcard. I thought it would help the overall story, and it tries to be subtle while doing so. Sometimes on layouts that are structured like framed paintings instead of sculptural objects you’ll see a lot of labels, stickers, photos, warnings, awards, and other ephemera attached to the surround. That’s all too loud and distracting for me. The layout needs to speak for itself. Likewise, dioramas need to speak for themselves. They shouldn’t need any supporting documentation or ephemera hanging around trying to divert attention.

Materials: Sheet Foam

I use foam sheets for my bases because they are lightweight, strong when laminated, easy to cut and shape, and low cost. I learned a hard lesson when I built the portable Lost Ocean Line layout from wood. It became too heavy to be very portable by me alone. Other materials can certainly be used. Foam sheets aren’t some magic one-size-fits-all solution, but I’d say put the wood back in the rack if it isn’t completely necessary. If you’re using wood for decorative reasons, that’s a different story.

Spare Moonscope wheel was used to roll in tracks.

On the Loonar Module I sided the base with sheet styrene to give it a smooth finish. I’ve subsequently learned that isn’t completely necessary. Smoothing the foam sides and then painting them with an artist’s quality acrylic will produce a decent finished surface. Although foam sides may seem a bit rough and soft after shaping and smoothing, the acrylic paint acts as a binder to solidify the surface as well as provide colour. Think of the paint job as applying a surface binder that just so happens to have a colour, which is black in my case. 

After 2 weeks of curing, cheap acrylic paints were used to colour the surface

Eye Level: An unresolved problem

I’ve always thought that the conventional way scale models (plastic models, train layouts, doll houses, every category really) are shown and displayed is odd. I think the best way to view them is at eye level because, usually, that’s how we encounter their real life counterparts. Yet, models are usually displayed so that the most common viewing angle is from above. I understand the practical reasons for this, but it doesn’t do justice to the models and the work of their makers. By setting out models on tables of conventional height only small children get the best views :-) 

Maybe conventional tables augmented with some sort of leg extensions would do the trick for model shows. Combined with showing dioramas or layouts with thick bases, this might almost solve the eye level viewing problem. Or maybe not. If you’re a long time reader here I’ve tried some experiments to fix this issue over the years, but haven’t been satisfied yet with the results. 

Ready for adding the models.

These aren't likely my final thoughts on the subject. They simply capture a few aspects of my current thinking. 

Oh, and before I run off for coffee, Sheperd Paine's book How to build Dioramas is always good to consult. Maybe I'll dive in again while coffee's brewing.

Awaiting the show.

Experimental Farm layout in January 2025 issue of Continental Modeller magazine

News Flash from the 30Squares Shameless Self-Promotion Department: The Experimental Farm layout appears in the January 2025 issue of Continental Modeller magazine! Six scintillating pages illustrated with 18 glorious, never seen before colour photographs! Just in time for Christmas: makes an excellent stocking stuffer for mom, dad, hubby, wifey, the kids, and that hard to buy for uncle! On sale now wherever fine model railway magazines are sold! Don't delay, get yours today!

Oh, no, I've worn out the ! key!

But seriously, I'm very happy that the editor at Continental Modeller published the story. Back in the 1970s when I was model railway obsessed I would often make the long hike from our house to the W H Smith in Scarborough Town Centre to peruse, and sometimes buy, English model railway magazines. That's how on one such mission I became familiar with Vivien Thompson's work in an issue of Model Railway Constructor.

To the best of my knowledge W H Smith hasn't had any stores in Canada, well, at least here in Ontario, for a very long time. But, my English cousin who lives in Solihull tells me there's one near his house and they stock Continental Modeller. It's quite satisfying to me that my first full length article has been published in an English model railway magazine and is for sale at Smith's. It's one of those 'circle of life' things :-)

MCM-7: A New Layout Genre?

Soon after taking pictures of the Le Grand DEFI dioramas on the family room coffee table I realized several of my layouts have been inadvertently sized to fit that piece of furniture. Maybe there's a new genre of layout in there somewhere?  

The 3 Le Grand DEFI dioramas

Ever since I stumbled across Bill Baron's mid-century modern coffee table layout proposal in the June 1966 issue of Model Railroader I've had thoughts of small, portable, and convivial family room layouts rattling around in my brain. I haven't explicitly set out to design one, but in a few cases it has worked out that way.

The Centennial Experimental Farm, aka the LOL III

The Micro-Layout category has an upper footprint limit of 3 to 4 square feet. My coffee table measures approximately 50" x 20", providing an area of a little under 7 sq. ft. for a layout. That's considerably bigger than the Micro-Layout maximum. 

Havelock Yard

Hence, maybe there's a new category in there for layouts that fit on a Mid-Century Modern coffee table of 7 sq. ft. or less: MCM-7 :-) And no overhanging, that's cheating :-)

Speaking of coffee, the family room is near the coffee machine and that's where I'm headed.

Replanting a mighty tree

Vicki's tree after planting in January

Back in January I finished and planted the large tree for the front of the Centennial Experimental Farm layout.

The 'prototype' tree outside Vicki's 

Paul noted the tree seemed too large and the bifurcation was too high off the ground. At the time I was obsessed with how big the tree was, so I didn't do anything. But, the comment kept rattling around in the back of my mind. 

As I was working on the Mt. Lowe layout I moved the Centennial Farm layout to a corner of the workshop to give me some extra elbow room. The farm was never out of sight, and I could see that tree in all its extra tall glory every time I worked on the Mt. Lowe track.

Drilling a deeper and wider hole for the tree

That constant visual reminder - nagging? :-) - convinced me that once I got the Mt. Lowe track functioning I'd reposition the tree.

And so I did. 

This change seems to have made a big difference in my opinion of the layout. It looks more balanced. Yeah, I still need to work on my technique for shaping and colouring bark; however, the overall scene is better.

Design Notes on Sight Lines: Roads, Paths, Sidewalks, and Track

Main street on LOL II, aka the 'Way Out Layout'

Photographing the Red Car Barn revived my thinking about an organizing principle I like a model railroad to have: lines I can sight down. Along with buildings one can see into and through, I consider interesting sight lines essential. I like to have a sun roof in a car too, but that's another story :-)

These lines can be provided by roads, paths, sidewalks, and of course track. It was on the LOL that I first played with lines, mainly through the addition of roads and sidewalks to connect the different parts of the layout. I'd look at various areas and think, could someone walk or drive or cycle there, or if they took the train or streetcar, how would they get around when they got off? I made physical changes in answer to those questions.

I think when I had developed the layout to a certain point sight lines became obscure, and that was a contributing factor to me taking the LOL apart. Looking back, when I added a shelf extension for the World's Biggest Bookstore I inadvertently changed a long, open view of the main street into a canyon that was harder to look into. Some interesting pictures resulted, but in the end it was limiting.

Ocean Alley

The follow up to the LOL, the never finished Alta Vista TC, was a sight lines disappointment. I didn't learn from bad sight lines created on the LOL. I built a main road on the Alta Vista TC for the streetcars walled in on both sides by buildings. I focused too much on having open real estate for buildings, and not enough on looking at them and the streetcars once everything was in place. I'd have to look over the back sides of the buildings to watch the streetcars. Eventually it seemed to me that as well as being far too big for my workshop, it didn't have enough possible views, and was going to become a boring exercise in making buildings simply to fill in open spaces along the main drag. The main drag was a going to be a drag.

So, on LOL II, the main street (still unnamed) is built up on just one side so I can get as many long views, or sideways panoramas, as I can dream up. There're no buildings 'on the other side' blocking my view. The one way street, Ocean Alley (name still up in the air), is a quasi-canyon: buildings on one side and a broken edge of trees, buildings, rocks, and small buildings on the other, but there's a long, so far interesting sight line.

Then there's the sight line from the parking / unloading track that starts at Ocean Alley and sticks into the pad where the urban buildings are located.

And there's the view down the track that runs along the edge of the beach. You can also see the parking / unloading track that intersects Ocean Alley that I previously mentioned.

The last long sight line runs along the dirt path that starts around the Red Car Barn, snakes past the surf shop, beachside cottages and the Ocean View Hotel, and ends at the Barbecue off in the distance  

The bird's eye view shows dense packed buildings in the urban area. From above it's certainly not realistic, but there is method to my madness.

A few months ago I was cleaning up the workshop and moving things around. I collected up all the little buildings I could see and randomly set them on the layout just to get them out of harm's way. All of the Toronto buildings went upstairs and were placed on a shelf.

After I'd done a bit of tidying up I glanced over at the layout and rather liked the jumble of structures. It had that packed in feel I was looking for. Organizationally it was wrong, but it felt right.

The next day I started to slide the models around, looking for sight lines and opening walkways to the sidewalk along Ocean Alley. This created a number of secondary and shorter sight lines out to the ocean. I also found many of the buildings were in need of minor repairs, so maintenance was done along with urban planning. 

Planning a downtown Toronto micro layout

I also realized that my Toronto buildings were going to need their own little layout to properly capture the feeling I wanted to get across with them - that's something else I wasn't able to accomplish with the Alta Vista TC. 

While in an urban planning mood I did a bit of fiddling with those buildings too to see if a micro-layout would suffice. It turned out a layout a little larger than micro sized might work, but development of that is for another time.

I'm not done fiddling with the LOL II's organization, but I feel it's heading in the right direction. Maybe it always will be just heading somewhere and never really arriving. That's ok as long as it keeps heading to interesting configurations. 

I know this isn't model railroading. It's just me creating a layout based on what I like and want to look at. It's just playing around.

Getting back to the LOL II, this is one of the secondary walkways that connects main street to Ocean Alley. At the entry is the Towers discount store on the left and the Chapters on the right. You can see one of the tall beach spotlights off in the distance.

There are 4 of these secondary sight lines branching off the main street.

I made sure the little Centennial Experimental Farm, LOL III, layout also had a main sight line: the pedestrian gravel path that runs the entire length of the layout from the street .....

... to the apex of the turn around loop. The visual implication is that the path crosses the road and leads to the farm's other facilities.

There's also a secondary sight line along the gravel path that is used to lead the cows from an off site barn to the pasture on the layout. It crosses a road and the streetcar has to stop at the crossing.

So the paths lead the eye into the layout and are used to imply there's a surrounding world of which this is a piece.

 

Establishing sight lines on the Loonar Module was tricky, and I wasn't completely successful. I think it's because the layout is basically a circle.

In this case I tried to establish two leading into the centre of the island. One runs from the end of the dock and up the concrete steps to the shed at the top...

... and the other extends from the end of the causeway, across the circular test track, and up the gravel road to the parking spot.

I think in this case the visual interest is created by the 4 separate scenes - which blend into each other as one walks around the layout - carved out by the tall trees, which create an effective visual barrier. The Toronto layout will also use tall elements - skyscrapers instead of trees - to separate scenes.

EVRR's valley beyond the long dividing trestle

I'm not sure if E. L. Moore's Elizabeth Valley RR had any distinctive or signature sight lines. It doesn't look like it did. Maybe along the trestle that divided the layout in two?

I think what it was famous for was it's level of completion. Being a rather small layout at 4'x6' it was a good showcase of what a model railroader of modest means could achieve. The level of detail and finish that went into the layout was impressive, even by today's standards.

If it did have dramatic sight lines they would be difficult to photograph as it's my understanding that E. L. Moore used a Graflex press camera. Even a 35 mm SLR would be difficult to maneuver in and amongst the layout's features for dramatic perspective photos. The N-scale tribute layout and a digital camera might uncover some interesting views.
