2015 Progress 1

Southside Industrial District in shadowbox relief.

When 2015 started, I had three major goals to achieve for my HO industrial switching layout.

  • Create a shadow box (or proscenium) arch valence for the front of the layout benchwork
  • Convert an old Athearn diesel switcher to battery powered radio control
  • Build a cardstock model of the UK Underground station at Morden

I am pleased to say I made major progress on two, while considering the proscenium arch completed. Scroll down through the blog to see construction articles. More on the London Underground coming in 2016!

Morden Station on the Northern Line of the UK Underground

While the bulk of Morden station is complete, I’d say the entire diorama is maybe 40% complete. I still have detailing to do like street markings, figures and general clutter. I’m also going add a couple of levels below grade to show some underground passenger service.

Rather ambitious, but I hope to get it done with a little help from my friends.

The Du Pont Washington Works is a major shipper on the Southside Industrial District. Rich Erwin explains how he made it.

The Du Pont Washington Works plant anchors the East end of my HO switching layout, the Southside Industrial District. The facility is actually a collection of buildings with three spurs for rail traffic. Track #4 receives shipments of various chemicals in tanker cars and the odd load of coal in hoppers. Track #5 is for receiving other raw material and equipment in boxcars, flats, and gondolas. Track #6 is for shipping plastic pellets in covered hoppers.


I used a mock up process to determine the size, color and placement of the main elements of the chemical plant. After mocking up, it was time to create the main warehouse building near the front of the layout. After seeing the mock ups, I had decided that the gray building was just too large and would go with some the size of the blue building I had tried out. I also liked the color, so blue it was. The modern warehouse would be modelled to represent corrugated aluminum, so prevelent in today’s industrial parks.

Blue warehouse #6 anchors the scene, while building #4 can be seen in the background. The other two buildings are still mockups at this point.

Du Pont warehouse number 6 is constructed from a foam core shell. I really love working with foam core because it is light, strong, easy to work with and cheap. I basically made a box with not top or bottom out of the stuff. In the past I had used white Elmer’s glue, but on this one I used a glue gun and liked the results. I temporarily pin the walls I am joining with whatever is handy. Track nails work well. Then I run a bead from the glue gun on the inside corner join. The “glue” in a glue gun is basically heated up silicon. When it cools, it hardens and acts like an adhesive. It will cool and set faster (a couple of minutes) than white glue (several hours or overnight), so I quite like the glue gun. A coat of a bright, medium-hue blue finished the core of the structure.

Du Pont warehouse #6 was scratch built using corrugated sheet styrene over a foam core shell.

I had planned the location of windows and doors on the front, and cut those out in advance. Once the box was assembled, I glued Evergreen corrugated siding to the sides of the front and long side facing the layout front. The other two sides would be hidden from view, so I did not add siding to them. The company I currently work for has a couple of similar buildings. I looked at them every day when I went to and from work to get the feel. They are really plain and reflect their function-over-form design priorities. Many are just large boxes of corrugated aluminum, which is what I wanted to model. I didn’t worry about too many details as far as the structure goes. The side and back walls have no windows or doors. The glazing and casting for the front entrance of the building came from my scrap box. The roof is card stock cut to fit with vents from Pikestuff.

All in all, I would say the building cost me about $10.00. The one thing that I find difficult in scratchbuilding is cutting the walls to the proper size. I just cannot cut as accurate by hand as a commercial casting. One alternative to scratch building this warehouse would be to bash some Pikestuff kits. What you spend in money you’ll save in time because you wont’ have to cut all the pieces to a custome size, though you’ll still need to do some work.

I finished off the area by adding piping made from a sprue from a previous kit. I got something that looked about the right size and painted it bright yellow. Yellow and blue are primary colors and by placing the pipe in front of the blue warehouse wall, the pipe stands out. I got a couple of brake wheels from old cheap railway cars, painted one white and one red and placed them above what appeared to be valves. I’m not exactly sure what the pipe does, but I think it looks pretty good.

A Little Help From My Friends

Next it was on to the background building that sits against the backdrop by track number 4. This spur forms a wedge with the layout edge, and models the lead to the storage of chemical cars (and the occasional coal hopper) to the complex. The administration building acts as a view block and this gives the impression that the tankers are going somewhere “over there” or “back there” which helps make the layout seem larger. The background building would represent the end of some type of manufacturing.

The red manufacturing building will go in the empty space to the left of the repurposed tank car.

To get the right feel and size for this building, I also used mockups. After the warehouse #6 was in place, I quickly made three different buildings for this area – 2 paper, and another corrugated warehouse type building set on a concrete skirting about 10 feet high. Then I took to the internet and asked for opinions and comments on what I had done so far.

Some early trial runs at sizing the background factory.

Early trial runs at sizing and fitting factory #4.

The cardstock buildings were photo realistic with nice detail, but they just didn’t feel right for this location. The area is wedge shaped and I wanted something with a sawtooth to fill the space. The paper buildings were also smaller and just didn’t produce the mass I was looking for. By building my own, I could make it any size and fit the space better.

Agian, I made a shell of foam core and glued corrugated styrene sheet over it. I raised the sheet about 1 1/2 inches up from the bottom to make a simulated concrete skirting. This I painted an ivory beige color. The rest of the building was painted a bright red (another primary color) to offset the blue warehouse. More spues were painted silver and used as piping.

I created vents for the sides of both buildings of various sizes by rotating the corrugated sheet 90 degrees and gluing that on a slightly larger plain styrene base. These were then painted silver or gray and glued over the corrugated siding of the walls.

I removed the chemical storage tanks at the back by building #4 because of a lack of space. I wanted any extra space to go to the background structure. This decision was also a result of the mock ups. I did find space for an old railway tank car turned into a storage tank. In due time this will be weathered so the Shell logotype is not so obvious. A photo of a chemical plant in the corner completes the scene and adds to the illusion of the complex extending beyond the edge of the layout.

The final two structures are still in mockup form. The administration or business bulding is a Swift meat packing plant from (now) Alpine models painted gray. The sandstone receiving building is poster board glued over corrugated cardboard. These help me determine the size, color, and placement of the final structures which will have a better level of modelling and detailing.

The white tanks at the front of the complex are for storage of outbound plastic pellets. In reality, a manufacturer of pellets would most certainly have many more tanks for loading covered hoppers, but I have modelled two. The tanks are made from plastic contact solution containers. They are glued together and joined them at the top with a walkway. Handrails and other details will be added later.

The pellet containers can be moved from their current positon to the “concrete” pad for an alternate arrangement. The concrete is poured plaster stained with an indian ink wash. This was originally the place for the gray building, but the mock up excercise showed this was a little cramped. I liked the broad view of a couple of colorful covered hoppers parked up against the deep blue of the warehouse. I can move the pellet tanks over to the concrete pad on a whim to give the complex a little different feel.


Signs are everywhere in the real world. Take a look around and see how many signs or advertisements you come across in you day to day lives. It’s like we humans wouldn’t be able to do anything without a sign to tell us what to do.

When I look at some of the urban modeling that inspires me, I find that the scenes have a lot of signs. The Southside Industrial District should be no different. Signage not only adds to realism, but can also help set the locale and era of a layout as well as literally spell out which industries are which or the function of certain elements that compose a scene.

For the chemical complex, I used the Du Pont logo to tie the buildings together and define the boundaries of the facility. Smaller signs are scattered throughout the scene and are typical of an industrial area. They identify buildings, convey general saftey information and identify places that might be dangerous.

Details, Details

Detailing comes next. I view detailing a model railroad the way a painter might consider a work of art in oils. I like to add details by applying them to a section in layers. A layer is completed before moving on. The layers are considered right from the beginning of building the pike through to the end. Actually it seems I never finish a scene, but keep tweaking it, changing, and making updates just as happens to any locale in real life. Here are what I consider to be the distict layers, in order from the first to the last:
1) benchwork and subroadbead (tabletop of plywood or foam)
2) roadbed, track, ballast, “classic” ground cover
3) backdrop including painted or photo scenes (my preference)
4) buildings, both foreground and background, city streets, small structures
5) detailing – signs, people, clutter, vehicles, etc.
6) weathering buildings, rolling stock,
7) more detailing

Right now on the Southside, I am working on layers 4 and 5, depending on the location within the layout.

I find details add a level of completion to a scene, as well as bring it to life. There can be just a few small additions that can totally make or change the feel of a scene.

Woodland Scenics ground cover did a lot to tie the scene together. I added clumps around structures – the abondonded tanker car, the chain link fence, the guard house. I used the finest grade between the rails on track #4 to get just a touch of grass growing on the lightly used spur. Yes, urban areas do have trees and I placed a couple next to building number 4 to help with the transition to the background. I could probably add another, taller tree here as well. I placed another tree near the guard shed.

Figures give life to the scene.

The lights are from Model Power and are place in sections of styrene tubing to lengthen them. I also placed one behind the guard house. A few vehicles and scale figures of people going about their work bring some life to the scene.

An etched brass chain link fence by Micro Engineering defines the edge of the Du Pont property. I bent the barbed wire to about 45 degrees with pliers and painted both sides with a dusting of red oxide primer. There was only enough fencing to span one half of the three places where the track enters the fence. The rest of these gates will need to be added later.

The main entrance to the facility contains a guard house, grade crossing, drop gate, and signage. The access road was built up to rail height using Sculptamold. I painted it with brown acrylic and then sanded it once completely set so freight cars could pass on the rails unobstructed.

I created the grade crossing by using half- height ties from Campbell Scale Models, circa 1979. First I “stained” them by rubbing on a brown acrylic paint with a rag. A couple of coats and wiping to get the effect I wanted. Then I glued them onto a piece of styrene of the correct size. This was then glued between the rails before ballasting. The guard house was a gift and originated as a European yard office from a shipping container. A Bachmann automated crossing gate was removed from its pre-fab base and added to the scene.

Moving On

The next natural steps will be to update the two remaining structures, weathering, and adding details. Track #5 still needs paving between the rails and the pavement could use some painted markings like lanes and edging. Tank piping and hand rails on the pellet tanks will need to be added. Pipes and more pipes, as well as general clutter. Finally, a few more signs will convey the importance of safety in the area and welcome guests to the Du Pont Washington Works plant.

 Base scenery work has been completed on the Dupont footprint using a variety of media. The immediate foreground uses pre-mixed joint compound to build up a base for the materials processing building. The compound was applied in layers up to rail height.

The area ended up being too dark and blended in with the building sitting atop it. No color was added to the top layer and it came out white. I gave a couple of washes of india ink to tone it down and bring out the detail.

Between the rails I wanted to simulate a black top area that trucks would use getting to and from the warehouse towards the back of the layout. I stacked two layers of 1/4″ card stock used for matting artwork. The first layer comes even with the top of the HO ties. The second is cut to fit and is just under the railhead. A layer of black poster board from Walmart tops the concoction. No painting is needed. Between the rails, I lay one layer of mat board is overlayed with a layer of .004 inch styrene cut to fit. This gives more clearance than the pavement on the outer rails and allows for more room for couplers and stock rolling over the area.

I like the styrene because it is a bit more robust and can be shaved and sanded for flange clearance. The styrene is affixed over the mat board using CA.The surface of the black top invariably gets scratched and bumped in the process of completing the scene. No problem. I patch using Sharpies and acrylic paints. The colors don’t exactly match, but that’s the look we want. Same thing happens on the prototype. Patches happen at different times and end up being different colors because of materials and fading.

More areas added

More areas added

The edges of the parking lot are blended down to base plywood level using Sculptamold. An access road from the Third Street was also built up using Sculptamold. I painted the Sculptamold using earth colored acrylics and used standard scenery techniques to top with ground foam and gravel as appropriate. A little ground foam in down the center of the road implies a low traffic area. Dirt and ground foam were added to blend into the previous scenery and track ballasted with a sand / dirt mix from my driveway.

Next come the buildings.

After a hiatus to put our house on the market (didn’t sell, staying where we are), I started on my chemical complex last night.

It is going to be a Dupont plastics processing plant, making plastic raw materials for other manufacturing firms. I’ve chosen to name the complex after that Dupont Washington Works that is located near my hometown of Parkersburg, WV. I won’t model the prototype directly, but a generic chemical plant that generates rail traffic.

The complex will consist of 6 structure groups – a large manufacturing building, a smaller materials processing plant, a shipping warehouse, a set of plastic pellet bin towers, a set of liquid chemical storage tanks, and an off-line office building closer to the urban district. See the diagram.

The complex will be fed by 3 tracks. The variety of in and out materials will provide the opportunity for different types of rail traffic. Loads will come in on covered hoppers (plastic pellets), tank cars (liquid chemicals), and box cars (various machinery, manufacturing and packing materials). A few hoppers of coal will be unloaded each week to generate heat and electricity for the manufacturing process. Loads out include chemical waste (tankers) and finished product (box car). Products will also be shipped by truck, which will be modelled by the warehouse.

Though the complex is active, I still want the look and feel of a space that has seen better days. There will be plenty of aged and derelict buildings. I’ve taken some inspiration (and backdrop scenes) from the Detroit Packard building, though it is a bit extreme. Lots of piping, tubes, and clutter will add interest to the scene. Most of the buildings will be scratchbuilt or kitbashed. The materials processing plant is an old Swift meat packing plant from Apline models that I build about 30 years ago. I’ve repainted it gray to simulate a concrete building. The main manufacturing will be scratchbuilt cardstock and the warehouse will be a Pikestuff warehouse modified to fit the space. Various pieces yet to be determined will represent tanks and the office building will be a Smalltown Vicky’s Fashions. Some sort of fencing and guard gate will finish off the complex.

I’ve started the paved area the under the materials processing by putting down drywall joint compound. I added black acrylic paint and spread out with a spatula. It is a little thick and hard to get smooth. I’ll try sanding once it is totally dry. Also, it shrinks a bit upon setting, causing cracks which is actually a nice effect. The tough part is controlling the amount of shrinkage, especially around the rail ties. I may have to add another layer or retouch before I’m happy.

The rest of the paved areas will be a combination of cardstock and styrene, which work successfully on the paving of Third Street. I’ll start that after I finish with the joint compound. I’ll also add ground cover, a dirt access road and details.
