FALLEN FLAG?
Topic: Ramblings

Several months have elapsed since the previous Journal entry. Those months have seen the closing of Augusta Station and my personal transition to a new life. It is still unknown if the Missouri Kansas and Pacific layout will make a similar transition. Augusta Station was both a model railroading project and a business venture. As a modeling project it was something of a success. Unfortunately, the business venture was not successful and the owners of the business were left with no choice but to end the business venture. Some contacts have been made which might allow the MK&P layout to become a small part of another business venture in another location with other owners. It is an uncertain future, however, and the layout as so many others may become nothing more than another load for a trash dumpster. So it may be time to reflect a little on what was learned during this modeling endeavor.
One thing demonstrated by the MK&P layout was not a new discovery, but a confirmation of my belief that N scale is not just for small spaces. In fact, N scale really comes into it's own in larger spaces. In a large space N scale can create sweeping scenic vistas which any other scale would be hard pressed to equal. Development of the layout did not progress to a stage where we could test the degree of detail which can be achieved in N scale. I have seen other layouts which do demonstrate that detailing is possible in N scale to a much higher degree than most persons might suppose. However that may be, the real strength of N scale will always reside in the ability to create big scenes be they magnificent mountain vistas or imposing industrial locations. If scenery is a strong interest for you, I can not think of any scale in which you would be happier.

Before starting this project I had read about building layouts using foam board insulation and also about bench work built with steel studs. I had no experience building with these products nor even seen them first hand. That may have been something of an advantage, however. There were few preconceived notions of how things were to be done. This left a lot of room for experimentation. I am now convinced I would never use any other method to build a layout. Two inch foam insulation mounted on top of an open grid of steel studs and topped off with Woodland Scenics foam risers is the easiest, least complicated, and quickest way of building I have seen. These materials have the further benefit of being uneffected by enviromental conditions of humidity and temperature.
A third thing learned, there is no better use of three inches of layout space than fluorescent lighting of your sky backdrop. This too was something I had seen written about but never witnessed first hand. No photograph can adequately show the profound effect up-lighting has when experienced in person. The flat blue wall behind the layout becomes a glowing, translucent sky. No need to worry about tricky painting techniques to achieve that graduated color from light blue at the horizon to the deep blue of the sky overhead. Just lay a string of T-8 fluorescent fixtures along the base of your sky backdrop. Then hide the fixtures behind scenery which now will be enhanced by a realistic sky. This single technique may do more than any other to lend believability to your scenery.
There were many small discoveries during the past six years. The condiment dispenser which I thought might be a good tool for gluing down ballast proved to be much better for spreading the dry ballast. Another style of condiment dispenser was successful as a glue applicator. A few discoveries were less than happy. Instant Water proved unsatisfactory as did the black tarry Instant Roadbed. Although we returned for a time to traditional cork, Vinyl-bed (a recycled foam vinyl product) was our final choice for roadbed. And mounting turnout machines on 1/4 inch plywood wasn't a good idea either. But unsatisfactory results are merely a provocation to to look for a more satisfactory method. Using .060 styrene was a much better way to mount turnouts and turnout motors on a foam based layout. Small lessons such as these taught a larger lesson. Progress may come at the expense of prior failures. Discoveries are never made by persons doing what people have always done. When on the cutting edge there is always the danger of some blood being shed. But with proper attention wounds will heal.
I think willingness to innovate typified much of what went into building the MK&P. Perhaps most of the innovations related to the bench work construction. While foam insulation has been seen in layout building for some time using it as a structural material is relatively recent. The transfer of steel studs from the building trades to model railroading is even newer. Because such applications are new, there are few examples and exactly how to utilize these materials has not been fully explored. Hence, there are plenty of opportunities to be creative.
Without previous experience in this type of construction, it took me awhile to understand how best to exploit these materials. Perhaps I am a little slow, but it took a bit of time to recognize some of the principles required by construction of this sort . The open grid of steel studs topped with two inch extruded foam insulation defines the lowest level for any track or scenic features. Plan ahead, you do not want to intrude upon that bottom two inches of foam with gullies or streambeds. Woodland Scenics foam risers and inclines raise the track above that level. To gain elevation most foam construction which I have seen stacks foam sheets like layers of a cake. While this technique is satisfactory for small changes in elevation, it will quickly consume large quantities of foam for major changes in elevation. I discovered a more efficient use of material was to build boxes of foam which can be stacked on top of each other to any desired height. I lost count of how many sheets of foam insulation came into the building. (Certainly more than enough to build a good sized home.) Almost nothing went out. Scraps find their way into later construction so there is almost no waste of materials.One thing which has always bothered me about building bench work it plywood is the tremendous piles of scrap wood it seems to generate.
An even more efficient use of materials is to adapt the technique frequently used for plywood bench work construction. In areas where there are no structures which need flat surfaces for support it is possible to use foam pylons (called"risers" in plywood parlance) to support a base for the track. This gives a good deal of flexibility for creating very rugged scenery. Cutting the foam sheets may seem to lead to the same wasted trimming as seen when cutting plywood. However, the foam scraps are very useful for constructing scenery. As seen in this photo, foam scraps can be used as struts to support the wire form over which plaster hardshell is to be laid. Foam scraps can be assembled in all sorts of arrangements to provide scenery forms. Foam insulation board is very versatile. It easily can be cut or shaped with a saw, knife, hot wire, hot knife, or Shurform tool. It is quickly held in place with a hot glue gun. No drills or screws required. 
We did make one major change in our construction method. We began with building individual tables supported with 2x2 legs. The tables were then joined together with sheet metal screws. While this worked it did have some problems. It was difficult to keep the joints between tables level. Flat and level bench work is essential for the best track laying. Even though derailments did not emerge as a problem I was not comfortable with this situation. The last segment of bench work was supported on continuous beams. This eliminated any problem maintaining a smooth transitions between sections of the steel grid. The beams in this case were a modified box beam. However, for any future construction we would have switched to "I" beams similar to those used for floor joists in home building. While the box beams worked well enough constructing them was too complicated.
In this bench work photo you will notice the bench work stands away from the wall. The resulting two foot wide aisle, accessible via a duckunder, accomplished two things. First was to provide access from both sides of the five foot wide bench. The second was to give access to hidden staging tracks to be located under the tall mountain ridge. Also note the ledge attached to the wall. A triple track continuation of the mainline would later be mounted on this four inch wide ledge to function as a hidden return route for trains. If you examine the previous photo of the pink foam, you can see an open box exists beneath the upper level of track roadway. This is the box where a hidden staging yard of fifteen tracks will be laid out.
Perhaps the last lesson learned was about track cleaning. With a layout as large as the MK&P there is a lot of track to keep clean. Track in the presence of on going construction and many visitors add to the track maintenance issues. Bright Boys, track cleaning cars, alcohol, paste polishes, and any number of track cleaning solutions were employed. It wasn't until the last couple months of operation, however, that I came upon the suggestion of mineral spirits as a cleaning treatment.
I made a trip the the paint department of the local Lowe's homebuilding store. With some denim scrap as a cleaning pad, I went to work with this new cleaning solution. I followed up with a quick pass of a Bright Boy to burnish the rails. The mineral spirits, just as other solvents and cleaners I had used. was effective at removing gunk from the rails. The real surprise was how long the cleaning lasted. I was able to run for weeks without repeating the task. I had discovered some time ago that running trains every day extended the time before cleaning needed to be done again. Likewise, I discovered that after not running trains for a couple days I almost always had to clean the rails again before I could run trains successfully. Not so after using the mineral spirits. With the curtailed schedule of operations which preceded the final closing of Augusta Station, there were extended periods during which trains were not run. It was a pleasant surprise to find that I did not need to clean track before resuming operations. I do not know but I suspect "mineral spirits" are a blend of mineral oil and alcohol or some similar solvent. Cleaning with mineral spirits leaves behind the slightest of oil film on the rails. I am supposing that this creates some sort of protection for the metal rails and perhaps improves electric conductivity. However it works it does work well as a track cleaner.
It has been a great six years creating the Missouri Kansas and Pacific layout. My only regret is that it could not continue. But life moves on. Right now my model railroading is in a forced hiatus. I am living in one of those infamous 10x12 spaces, a dorm room which I share with a roommate. Although he is a pleasant fellow he is not a model railroader. I have no idea how I could accomodate a paint booth or even a mini table saw into this space. It has been very difficult to manage even a computer and a printer. So, for the time being at least, I have returned to an earlier condition of armchair modeling.
But if at some future date I have an opportunity to build another layout, even if it were only a 10x12 space, how would I build it? I would definitely build my bench work with steel studs and rigid extruded foam insulation resting on "I" beams. Woodland Scenics foam risers and inclines would provide the base for my track. The track would be laid on Vinyl-bed roadbed. The track would be Micro Engineering code 55 weathered rail. I would use Atlas rail joiners, turnouts, and switch machines. I would continue to assemble the turnouts on .060" styrene. Notice a pattern here? Yes, I would build my new layout pretty much with the same materials and techniques we developed over the six years building the MK&P. I would hope to avoid any of the design mistakes which were made along the way. And there were a few, but by in large I was happy with the layout we built.
My move to Arizona has opened a part of railroading of which I previously had little or no awareness. The railroads which historically existed around the former copper mining town of Jerome would make fascinating model subjects. And the BNSF raceway across northern Arizona offers plenty of action with nearly non-stop container trains. Add in some manifest freights, Amtrak, and a couple tourist railroads and there is more than enough to keep a railfan happy. In fact I see one of those tourist railroads every day. And while I am no longer on the leading edge of model railroading, I am on living on the edge of something pretty big. You see, I am now living in Grand Canyon National Park and working in the El Tovar Hotel made famous by Fred Harvey and the Santa Fe Railroad.
