Service is now running from the village sub-terra station to the mine.

The futuristic turbo train departs for the mines of Xenon on Rich Erwin’s sci-fi model railroad

I’m writing a mixed-bag status update today. I’ve painted and put in place, at least temporarily, the passenger line from the village to the mine. The configuration is a loop and the plan is to have a station at the mine (underground, hewn out of rock, etc.) to the “village” where miners live and the extracted minerals are processed and loaded for shipment.

Overview of The Mines of Xenon science fiction model railroad

 

The village station (approximately where the turbo train is in the picture above) will be a “sub-terra” (that is, subway) station, also within rock.  Available space will determine the size of the stations, but I’d like to have a pretty substantial one as in my practice diorama.

This is the steel track included in the Tyco Turbo Train set plus a couple of extra pieces I surprisingly found in my scrap box. The steel is used because the Turbo Train uses magnets to maintain contact with the track. I painted the passenger line white to set it off visually from the freight line. I’m also considering using the vertical spacers that come with the train set to make it appear more like an elevated passenger track. I think the contrast is nice, but I still have to paint the re-railer / power section which is a bit quirky.

I’m getting ready to do some body work on the diesel roster. I have a box full of shells (most of which are courtesy of Jack Hess of the “Colony 5” work in Railroad Model Craftsman) and I am quite enjoying stripping the paint off. Just soaking 2-3 days in 91% alcohol and scrub with a toothbrush. Jack had already started some work, and I continue to imagine what a heavily kitbashed alien engine might look like.

IMG_1049

Remember, the layout depicts the early hours after the AI mechs are attacking and the humans must scrounge for raw materials for protection. Think Mad Max style trains. The idea is that I will take the bodies of disparate engine styles and cram them together for something that is recognizable, yet foreign. This could be fun if I don’t stress and let the process come.

IMG_1048

A secondary technique is to leave the paint bubbled as a weathering effect. I’m looking forward to using this in the future, but for now I’m stripping everything off.

Next up is ballasting. Again I wanted something familiar, yet different. Typical model railroad ballast would be just too ordinary. I considered kitty litter or aquarium pebbles. A little research and I thought both those items would be too large for HO scale (but probably acceptable if nothing else could be found).

I’m pursuing using construction sand that I snagged from a friend. It comes from a big box store and I got about two pounds worth. I dried it out and the sample seemed to have a pinkish hue. I had in my mind something darker and more red. So I painted it. I simply dropped some of the same paint from the baseboard stage and mixed in a red party cup. Let that dry and voila!

IMG_1057

Dried construction sand on the left, painted sand on the right

 

The sand clumps slightly as it dries, which turns out is a nice effect. The grains themselves are a bit small for a ballast (although who knows what they use on Xenon 3!) so the larger clumps work out nicely.

I’m happy with the results and think I’m going to go with the painted sand. This turns out to be quite a versatile and cheap method. You don’t need very much paint and I guess acrylic would work as well as the latex house paint.

I ballasted two small sections of track – one with the original sand and one with the painted. I’ll have my little helper give the final verdict with a little input from dad.

IMG_1059

Finally I’d like to share a nice little find. I was looking for plastic containers to hold the diesel shell parts (window glazing, handrails, horns) while stripping paint. I went strolling down the aisles of my local grocery story and found some cheap lunch containers with sections. Neato and I think I’ll be using these again and again for various projects to come.

IMG_1058

So now it is on to installing a couple of bridges and securing the ballast and track.

Work has begun in earnest on filling the swamp. I had already coated the bottom with joint compound, sanded and painted it. Light green on the outside, blending to a black in the middle represent depth.

I had also fashioned a couple of industrial pipes from PVC and a prescription pill bottle and added toxic drainage. A how-to video by Wyloch can be see here: https://www.youtube.com/watch?v=S07hHjXgd60

Now it was time to add some detail to the area. I cut a dollar-store toy dinosaur in half for the “swamp monster” emerging from the pool of blech at the waterline. Paintbrush bristles and Noch static grass were glued in to represent whatever type of wild reed grows on Xenon 3. I also added part of toy dinosaur skeleton tail.

Next I poured the resin. About 20oz of both resin and hardener were enough to lay down a layer of about 1/4″ inch thick. I let it cure and harden at least 48 hours.

Next comes the magic. The resin dries incredibly clear. Every fault from the plaster and paint can be clearly seen.  The resin, as poured, needs some texture and color variation to get the light to play and bounce. This can be achieved by adding some acrylic paint to the resin pour, but it was too late for that now (note to self: add some color to the resin next time. Fluorescent or glow in the dark?)

20170802_201847

I remembered technique of making water of nothing but coats of Mod Podge by long time Model Railroader Magazine contributor Dave Frary. The effect is stunning and explained on Dave’s Youtube page here: https://www.youtube.com/watch?v=wnOE-qWhGVs

Even though the effect of building up the coast of Mod Podge is amazing, the bottom layer of paint also counts for a lot as well. Again, a lesson for the main layout, but now time to start laying down the layers. As the video states, blotching is key. Thicker layers are better, but tend to cause air bubbles, which destroy the effect.

This is a fun task where you can get a little help from your assistant. You can do at least 1 coat a day, two for the thinner ones.

20170802_201201

On the backside of the diorama, which is the underground sub station, I started placing in the various elements, The platform and bulkhead are basically finished. I tested coloring the ties white to differentiate the passenger line. I made some other pieces out of sci fi gaming textures from the Internet. I still need to add some details to get a grungy, sci-fi, post apocalyptic feel, as well as a futuristic train or locomotive, low level lighting, and passengers on the platform.

20170730_184309

Over on the main layout, it is time to start laying track. I have put in place the cornerstone pieces (basically the switches) which will key the placement of the rest of the track. There will 5 electrical blocks (standard DC block wiring), so I mocked in some curves and identified where the feeders will need to be.

20170802_201903

I drilled the holes and will start laying the track for real next week. Soon trains will be running on the Mines of Xenon!

 

20170723_214606

Lots of progress the last couple of days, mostly on the diorama. Subway station 8C is getting bulkheads, doors, a platform and track. The main bulkhead is corrugated cardboard with one paper side removed. Doors are sci-fi textures downloaded from the internet and glued to foam core. A few things left there to finish up.

The swamp is coming along, too. I touched up the bottom and believe the industrial piping to be done. I’m gathering scatter and junk to function as flotsam, and we’ll start gluing those down shortly.

20170723_210009

The base coat is down on the layout, and next I’ll spay on a few coats from rattle cans to give the terrain some texture. The test on the diorama seemed to come out well. Track laying is imminent.

20170723_210753

Last week, a tradesman came to the house for a service call. I moved the Southside Industrial District so he could access a utility space. While moving the layout, the legs became unstable, so I’ve spent the last week repairing and strengthening those. They’ve been on casters for several months now and I love that feature of the layout. But it has forced a slight digression from working on The Mines of Xenon 3.

Speaking of Xenon 3, I bit the bullet there, too. I wasn’t happy with the strength of the so called benchwork, so I built a proper frame from 1×4’s.

20170708_135602

I had laid all the track out with the final trackplan, so before starting, I marked the location of the track. Since any marks on the foam would be painted over, I keyed on the two main turnouts and outlined them in the foam by applying a little pressure with a pencil.

There was also a wee bit of warpage, so I flipped the layout and put weights on it for 48 hours or so, so it would lay flat.

20170708_141223

Instead of placing the layout (1″ extruded foam over 1/4″ plywood) directly on top of a completed frame, I turned the layout over and built the frame around it. This resulted in the top of the baseboard lying flush with the top of the frame. For the first time in building benchwork, I laid the cross members horizontal. This gives more surface area for the plywood to make contact (since I can’t practically nail through the foam) for gluing, as well as making space should I decide to add hardware for folding legs. The result is a strong and sturdy benchwork durable enough for leaning or the likes of an 8-year old.

Work continues on the diorama. I decided not to try and smooth out the layers into a standard hill formation that we see in model railroads. The resulting layers appear to accent the stratifications that would result in a mining operation. Well, on Xenon 3, anyway! I used SculptaMold to give some texture to the flat surfaces. I layered on ruddish colors of spray paint to give the final look.

20170702_185002

The bottom of the swamp has been painted, and some industrial pipes created to dump sludge from the mining operation into the pit. Various shades of green were used, with the color getting gradually darker towards the center. Next, I’ll glue some weeds and debris to the bottom before pouring over a resin.

20170708_140007

Work is also going on on the backside where the underground subway station is. I’m working on using corrugated cardboard for the bulkheads with doors and access made from printed texture glued to foam core. I’ll add some expanding squirt foam insulation for effect. There are lots of possibilities here.

The foam is painted on the main layout, and I have been acquiring the switches for the control panel little by little. Just a bit more base scenery, and hopefully, trains will be running soon!

 

20170705_180832Yes, OK, so it is Xenon 3, not Mars, but we are having a practice go at a making foreign world. I used the left over 2×4′ section to start making up a diorama that will resemble the final Mines of Xenon train layout.

I wanted to get some practice using the extruded foam (XPS), shaping it, painting it and working with it in general. Also wanted a trial run at the slime pit swamp. That will give us some training using the planned resin as a medium for making the swamp. We’ll work on the color scheme and scale.

20170702_185047

Eventually, on the diorama, we’ll also build an industrial building to scale and map out the mine structure, as well as textures for raw materials. But that is still to come.

On the main layout, I think I’ve decided on a track plan. I wanted lots of features, but when in doubt, keep it simple. The Tyco Turbo Train runs on (magnetic) steel track, but had some trouble traversing turnouts since it essentially a slot car mechanism. (Have I said it is lots of fun, though?). So I made a simple loop to go around the perimeter of the benchwork.

20170705_180711

The mining branch is another independent loop with a passing siding on one end through the mountain. That allows for an empties/loads operating sequence. There are also two spurs which lead to the barracks and freight depot. All curves are 18″, number 4 turnouts, code 100 rail, with 5 block sections.

I’m not happy with the support, so first thing is to shore that up with a benchwork frame made of 1×4″ dimensional lumber. We’ll do that in parallel as we continue to work on the diorama.

20170616_203500I’ve started gathering raw materials for what is now being called “Mines of Xenon”. Shopping is taking on a whole new dimension. I’m seeing things with all new eyes and it is so fun! Previously, I would look at toys and odd shaped containes with the view of how they could be used to augment a mill or factory model to make a model look more realistic. Now, robots, super heroes and spacecraft are all fair game for inclusion on the science fiction train terrain of the future.

20170615_220929

While poking around eBay, the first thing I found was Tyco Turbo Train from 1986. I snagged it for $25 – a steal compared to the $499 list price on Amazon. It is so cool. Then a visit to the dollar store and grocery store produced a robot, 2 dinosaurs and a couple of souped-up Hot Wheels.

20170616_203343

I’ve also discovered the world of Sci-Fi war gaming terrain. I’m busy searching for images on the internet and putting together an idea book of images and concepts.

sharp3070.us@om.org_20170624_095243_0001

My daughter and I have put a few pieces of snap track to determine the layout geometry and I believe I’ve come up with a final trackplan. The Tyco train runs on the old Tyco steel track, and has trouble with turnouts, so it is better to keep that loop separate and have two independent lines working. There will be an outer turbo passenger track (it goes really fast!) and the inner mining track with a passing siding under a mountain and a couple of industry spurs. This will be standard brass or nickle silver and electric switch machines. Standard “first ‘real’ layout” kind of stuff. We’ll go DC control with blocks that can be turned switched on or off.

I also snagged a Bachmann 44-ton switcher which has a nice size of a layout of this type – small wheel base with two electrified 4-wheel truck to keep contact. Of course at anytime we can add a battery powered radio control motive power with no changes to wiring.

20170623_190338

The idea book is coming together and I am spending many nights a week in the basement with my daughter as she helps and learns. I can imagine my time for the next few weeks will be divided between Google image search, eBay and the basement. So much fun!

Rich Erwin freshens up the Southside Industrial District and addresses some nagging scenery issues

 

So, after a house move and some space prep, the time had come to clean things up a bit. I wanted to fix a couple of dings as a result of the move, enhance and correct some benchwork, and  tackle a couple of nagging issues with the scenery (paved areas).

First the benchwork. I reassembled the layout on its base legs. Since the new space isn’t finished yet, I had a pretty good inkling that I would be moving the layout a fair amount while things got sorted out. I turned the layout over, being carful to damage as little of the scenery as possible. Then I added 1/4″ center post casters I picked up from a big box home construction store. Flipped the layout back over and we were ready to go. The locking casters made a big improvement and maybe my best move yet.

20170217_220604

The District in its new space with rolling casters and an upgraded backdrop

 

Next up was the backdrop. For whatever reason, the current backdrop had about 1/2″ gap down the center. I don’t know if I originally measured wrong or what, but it had been like that for 3 or 4 years. Now was the time to fix it. I got a new 8′ section of 1/4″ Masonite and cut it to fit. It was long enough for a single piece to span the length of the back of the layout. I attached 1×3″ bracing to the back with Gorilla glue and painted the smooth side the same sky blue as the side boards. I attached it with clamps and drilled holes to match the existing holes in the frame. One quarter inch bolts with washers and wing nuts secured the backdrop to the benchwork frame.

On the backdrop I use photos of real scenes to fill the space between buildings. I still had the original backdrop and reference photos, so I peeled the photos off the backdrop and re-affixed them to the new backdrop. Another step done.

Painting the backdrop

 

 

The sidewalks at the back of the layout needed attention, so that was my first modeling chore. It was pretty straightforward. I use .060″ styrene cut to fit for the raised sidewalks. and I scribed in expansion marks every 1 inch. I then added curbstones with a width of 1cm, rounded the corners at the intersections, and beveled for crosswalks and driveways. I follow that up with spray painting the sidewalkes with textured sandstone. I carved in some cracks and applied a dark wash for weathering (and to bring out the detail) which completes the work before I glue it in place.

On to the pavement issues. The paved areas consist of several materials. Most was either painted styrene or cardstock. At one point I used thin black card which was essentially black poster board without a sealed surface. This was mostly used in the Du Pont area. In an Georgia garage with no climate control, this thin and unsealed stock had warped in a few places, especially around the track rail. Also, on the west (left) side, there was no pavement under the track or up even with the railheads.

20161202_221104

Pavement redo with styrene at Du Pont

 

First on the list was the cardstock at Du Pont. I pulled the paper layer off, being careful to preserve the shape as a template for the new material. The bottom layer, even with the top of the ties, remained. I used a .030″ styrene stock and traced the piece of card on the styrene and cut to fit. I sprayed a base coat of black primer and then highlighted areas with gray to represent traffic patterns. I added some arrows and street markings with oil pastels and traffic templates (made for UK roads). Of the three sections, I replaced the two closest to the front of the layout and left the back section intact, as it is mostly hidden and in the best shape.

20170406_212809

Finished Du Pont section complete with road markings. Note the weathering indicating traffic patterns.

 

The paving on the west section was next. I did some research and wanted to try some differing techniques to see which provided better results. Three sections to process (plus between the rails), so for each I would try a different material. On the back section by Sylvan Foods, I used black foam core with the paper backing removed after soaking in water. The pieces were cut to fit and sanded. The resulting texture was a nice rough one, simulating a paved surface.

20170305_201644

Plaster used to fill in the space between spurs on the west end of the Southside Industrial District. Wax paper and painters’ tape protect the track work.

 

For the area between the tracks of National Transfer and Storage and Sylvan Foods, I took a page from the old-school plaster playbook. I needed 1/10 of an inch, plus the height of the ties, for code 100 track, so I applied in layers, let dry, sand, repeat. Finally I painted a coat of black/gray acryllic mix and added some chalk for weathering. This took a couple of weeks not necessarily would I call it messy, but I did feel that doing each layer was burdensome – having to repeat the cycle of wait and sand, wait and sand.

20170331_204430

Weights assure a good bond for the foam core paving onto the benchwork top

 

Finally back to foam core for the base under the National Transfer and Storage. I made it a little larger and shaped and sanded to fit the existing access road.

20170406_212628

The completed scene includes pavement made out of five different materials: card stock, foam core, styrene, craft foam, and plaster

 

So now these nagging little projects are done, I can get on to the next thing. We often forget that track is scenery, too, and with just this little bit of effort, the layout feels more complete, and has a more finished appearance. On to detailing the city!
