Foam...
OK, I have read all the stuff about enclosing it if used for insulation, don't want to discuss that further.
Here is my question: Down here where structures are mostly cement block or tilt-up walls, there are TONS of "artchitectual" foam prioducts used. These make a boring cement building have character, inside and out, by adding formed foam pieces to make the building look interesting.
Columns, headers, textured wall surfaces, things that look like ornamental masonry, and so on can all be made of foam.
These foam products are not inside walls or fire protected. They get glued in place and painted.
I think 50% of the interior and 25% of the exterior of the local Shriner's Temple is made of foam.

Living the dream.
I've had zero issues with both Tortoises and servos running through foam. Heck, my last layout had 2 latyers of 2" foam, plus 1/4" plywood on the bottom and cork roadbed on top. Servos mounted underneath, ont he bottom of the plywood, driving turnouts up through the plyood, 2 layers fo foam, and cork. No issue, just needed somethign stiffer than .025 piano wire - I think I used .039. Worked exactly the same as installing one under a thinner base. Drilled a hole under the throwbar, ran the wire up from the bottom. The only 'difficult' part was I had to get a long drill bit, but they are easy to find in various sizes at any hardware store or big box store.

My crawlspace is about 3500 square feet and the walls just have extruded foam glued to the foundation and it is not covered. It flooded 3 years ago when a city pipe blocked, some of the foam sheets popped off and were floating around. The restoration company glued them back on after everything was clean and dry and sprayed for mould. The city inspector came once the work was done and the insurance company also sent an inspector to make sure things were done right.
I know that other houses in the area have bare foam on the walls of the foundation as we do, it gets warm down there in the winter from the heating ducts and you can bet that air makes it up to the living area. I guess I am doomed as are all my neighbours.

Well if you worry about layout foam, you can really worry about couch foam whos fire retardants are way more toxic than beaded foam. In a home (depending on your policy) a model railroad is proubly considered furniture and the trains themselves as something else both would fall under personal possesions, except for any rare item which could be a whole other peice of wax.

Let me address the foam, no you do not use grinders or sanders or rasps with beaded foam. Very sharp knives to get to within hot wire cutting range are the norm, you can carve some after with very sharp blades (I use $ store ones with the breakoff blades fully extended). No I am not advocation for foam, just what I use and the thickness required with foam only makes using a lot of switch controlers (except manual) a pain to use.
rrinker We are a stubborn lot, it seems. But really, some things deserve to be at least tried to form a valid opinion - I can't be the only one who was always hit with "how do you know you don't like it if you never tried it?" as a kid. There are very few things I can say I will not eat that I haven't at least tried, in some cases more than once in case I got a bad version the first time out, but twice and I don;t like it - it's off the menu. Without some willingness to try new ideas, I never would have tried extruded foam - first time I saw it was in a couple of Bill Darnaby's articles on it many years ago. Without a willingness to try, I never would have tried caulk for roadbed and track - and be completely converted to the method. Without being willing to try, I never would have tried using servos as a replacement for expensive Tortoises - to the point of finding them so useful that there is zero reason to switch back, especially as Tortoises have only gotten more expensive since then. Not everything I tried, I liked. There was a lot of general badmouthing of MRC sound decoders a while back. So I got one that fit a locoe I was wanting to put a decoder in anyway, to see for myself what they were like (I already had some other brands of sound decoders). Only positive I can say is, it was cheap. It sounds little like the Alco prime mover it is supposed to be, and while it has some 30 different horns to select from, my response from MRC tech support on which horn each value of the CV was supposed to be was "we don't keep track of that information" What? And the motor control isn't all that hot, either. So I guess if you want cheap noise that sounds mostly like, well, noise, go for it. But my criticism doesn't come from hearsay, I tried it myself. --Randy

I will try new stuff, I too was quickly converted to gluing down flex track.
Servos, I'm not interested in building the electrical side of that equation, it does not really fit my existing control method and I already have a LOT of Tortoises, and I'm not a "hodge podge" guy, so I want/need them to all be the same. No apparent benefit to changing.
Foam, ok, maybe for scenery, but not to put track on.
DCC and sound, tried it out plenty on other people's layouts, not worth the extra time or money to me.
I know many people on here think I'm just stuck in the past, but I have evaluated carefully most all of the new stuff I have "rejected".
Just like most of them reject ideas I find important like signaling, equalized metal trucks, 36" minimum curves, selectively compressed passenger cars, touching/working diaphragms, etc.
But yes, as a group we can be stubborn.......

I remember in high school that our illustrious wood shop teacher was asked to make a large Alladin's Lamp for a shool play. He chose to use several sheets of white styrofoam. He glued them into a large block and then began forming it into the desired shape using a coarse sanding disc. We came into the shop for our regular class and everyone started to laugh. The teacher was covered head to foot in little foam beads, as was everything within about a 10' radius. It didn't help that he apparently used the same hair stylist as Albert Einstein. Of course he told us to stop laughing, but that proved to be difficult. We spent most of the class chuckling at his futile attempts to brush the bits of foam off. It took days to clean all the foam up!
Fond memories!

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
I don't know how you could classify it as a myth that those bead board beads get everywhere. I look directly at a piece of it and beads end up in other rooms, inside shoes, and all over the cat.
Like I said, your couch has more foam than most layouts, I have two and each one equals the amount of foam by volume and I am over estimating the layout foam, add the pillows and, well you get the picture. But back to the original question, I did not say foam was best, just what I use because I find it easier to use. Another example, I use zip texturing and on my last layout had some issues, do you think I could find answers, even asked persolally the owner of another forum that like zip, no answers so after much experimenting I found the answered but it stopped construction for a month or so (also of note, most of the layout was done like this already).
Regarding most foam products -
The problem isn't the foam burning, but the copious amounts of toxic gasses it gives off when it gets really hot (and really hot is upwards of 1000 degrees F, which is the case for most home fires). Firefighters, with their self contained oxygen systems, are protected. But the occupants of the building are not.
I was a volunteer firefighter for several years. At the academy, we spent a few hours talking about the hazards of foam in a burning house.

PRR8259I have privately contacted a few people but not to trash them.
With only very few exceptions, the private messages I receive from forum members are all very positive and welcomed. I hope I did not give the impression the PMs were being used frequently to talk garbage.
ATLANTIC CENTRALSome prefer consistancy, example, using all the same type of switch machine, or the same brand of turnout.
I am one of these folks. Walthers/Shinohara and Tortoises only.
selectorWhat I like about this forum is that people DO come here and argue about stuff. It makes for a greatly extended range in both factual information
I have learned more from arguments than I do from other types of discussion.
AS LONG AS: Both people are talking in facts and neither one is just making things up.
Lately, some arguments in here have been between someone who posts something incorrect because they don't know the subject, then defending the incorrect information because they will not admit they are wrong.
That wears on me.
If I'm outlining and demonstrating a project or process, I try to be as clear and concise as possible, both in the wording and the illustrations, and try to always include the fact that what I offer is merely my take on the subect, not the ony way to do it, or perhaps not even the best way.
I do notice lately that there seem to be a lot more pontificators here than usual, and while some do offer useful information, the attitudes seem somewhat more strident than those to which we're normally exposed.In some ways, things seem to be drifting back to the attitudes seen here when I first joined, where some high-hats seemed to take joy in cutting-up newbies or less-accomplished modellers...our late friend Jeffrey was a victim of that, and I was appalled by those attitudes, almost to the point of quitting. I did invite him to join my "home" Forum, where he got a much more positive reception, and I was glad when things here finally began to become more inclusive for newbies.

I don't have a lot of history with PM's, maybe 300 so far in all my time on the forum (Jan 2005). A few have been critical of what I posted, some supportive, some asking for some kind of help or affirmation for something they have been criticized for... Often it's just the usual commiseration between two like-minded people on an issue. So, I feel badly for those whose experience with PM's has tended toward being forgettable or downright nasty.
I can't possibly know everything, and if I'm honest with myself (and others), I get my nose rubbed in that fact every single day. But, as others have said, we're all different and we all come to a problem with different histories, skills, knowledge, limits to success and resources, and motivation. What I like about this forum is that people DO come here and argue about stuff. It makes for a greatly extended range in both factual information (eg, ways to accomplish the same goal) and in reasoning or rationalization. I think it's best that we exchange views, skills, photos, our journeys through the hobby, and why we do things we feel should be done the WAY we feel they should be done. This richness gives each of us a greater range of choices.
We can agree to disagree. We needn't be disagreeable in expressing our contrarian views. We can respect each other as brothers and sisters in a worthy hobby that has far more silent members than outspoken ones. I can still like you, sight unseen, and still value and respect your dissent if/when I can't win you over to my way of seeing the problem.
A warm greeting to all my friends here.
ATLANTIC CENTRALOthers will have a hodge podge of what they feel will work in a given situation.
This is me when it comes to the layout. Current layout has foam, spline, steel, cement and plywood for roadbed/sub roadbed. Terrain is foam, Plaster of Paris and hydrocal and I am sure other things. We just did a bathroom and used some new products on that, I had leftovers in the bucket that went on the layout.
This stretch over the fireplace is a real collection of various cement type products and when I get around to painting it, I think it will look really good.
rrinker But - you will find the National Fire Code says this stuff is to be used only for insulation, and must be covered up, not exposed. When the whole wall is covered with this stuff in a vertical alignment, instead of horizontal model railroad benchwork, the results may not be the same.

This is a good point. Urethane foam was thought to be relatively fire resistant but when used for walls it turned out to be a firetrap. The root cause of the flammability in the "real world" was relatively still hot air air causing the urethane to release flammable vapors which then "pooled" against the ceiling. Ignition of the vapors creates a very scary flashover.
A few more thoughts:
Greg commented above that there is often "no one right way", so very true.
Some people see no need to change things that have worked for them for years, or decades.
Others see some value in always being on the "cutting edge" of new methods.
Some prefer consistancy, example, using all the same type of switch machine, or the same brand of turnout.
Others will have a hodge podge of what they feel will work in a given situation.
Some are very picky about accuracy or detail levels, some not so much.
These kinds of views also effect the answers people provide to questions.
I have privately contacted a few people but not to trash them.
Some will never see eye to eye with me and I avoid getting into any debate with them...all it does is stress me out.
good enough vs esoteric concerns. it's for personal use, not for commercial sale
in most cases, there is no one right way. It depends on the goal, situation, skills and tools
unfortunately, it takes experience to learn how as well as how to digest forum comments
greg - Philadelphia & Reading / Reading
My only opinion on foam is I want things to be stronger, and I don't like working with it.
Others are encouraged to do what works for them.
I work in construction and I only think there are a few good uses for it there as well. JUST MY OPINION.
Years ago on here I was called some pretty ugly names because I challenged the idea that everyone should switch to DCC.
And then again when I demonstrated with facts that REBOXX was recommending the wrong size axles for Kadee sprung trucks. I was told that Intermountain wheel sets would not work in Kadee freight trucks, despite my own experiance with about 500 freight cars - and then another guy spoke up and said he too used Intermountain wheelsets in Kadee trucks with the same great results.
I'm amazed at what some people in this hobby don't know, or have not bothered to learn, about trains, model or prototype.
I try to offer what I have learned, and I skip over threads where I have nothing to offer.
I get criticized still by a few for repeating some information, but it is clear that not everyone reads every every thread, so if it applies I repeat it, including my personal views on some things, which I think have bearing on some of the technical info I try to share.
Notice I almost never post in threads regarding N scale - I have ZERO practical experiance - and honestly, zero interest.
Why do some people act the way they do on here? I don't know. I will leave that to my wife the counselor.
I know my behavior has not always been perfect, but I try to offer what I know, and learn what I can.
Just to note I use packing foam too but everything ends up covered.
Now some of these things may be based in what was. Being in the trades I tried some of the water based interior gloss paints when they first started coming out, things would stick to it even months after applied, they fixed that (but Lowes recently sold some paint that did this, someone made a boo-boo).
Sure, whenever people have, and express, an opinion they are likely to be dogmatic about it because, well, because that is what they think. It is when they continue to think that even in the face of people who show visual evidence of very different results or experiences with the same product or technique -- hey, the bumblebee flies! -- that it gets disappointing.
When the very first resin based kits were introduced I can recall modelers saying that this was the worst possible material for making models out of -- they should cast in metal, never resin. Now some modelers regard resin as the only type of kit they would even consider building or running on their prototype based layouts.
Back when solvent based paints like Floquil were still freely available, you often read opinions that it was not possible to get good results painting metal or plastic using non solvent based paints. And then of course we all HAD to get good results using non solvent based paints and those objections either went away or were rephrased. I remember one time in MR Andy Sperandeo opined that weathering with chalks didn't work and was not a good idea. I was getting good results and wrote a letter to the editor (which was published) disagreeing with Andy. I doubt if I changed his mind however. And by the way back before Andy Sperandeo was an editor at Kalmbach his first appearance in the magazine was a letter to the editor saying that Kadee coupler's "delayed action" was a terrible thing and nobody should use that feature and that Model Railroader should stop pushing it on people. Then editor Linn Westcott's bewildered reply was "when did we push it on people?"
But there has to be an "on the other hand" so here is my "on the other hand." I'd just observe that there are many varieties of beaded (white) foam products out there, of various densities and makeups. Some types used in packaging of electronics for example seem very different -- more "beady" if that is a word -- than what Woodland Scenics makes and sells. And some seems more like the consistency of rice crackers in that the beads are not rounded or separate at all.
There are some of these bead boards -- usually the free ones from packaging -- that seem to release the beads everywhere even when just being cut with a sharp knife, much less a razor saw. I assume these are shapes using minimal heat to create to save money. If that is what someone used then their views on using it will be negative and dogmatic.
And while toxicity is not to be measured by odor, I also notice somewhat different smells from taking a hot knife or hot wire to various types of beaded foam product.
So consider those who seem dogmatic on a topic may well be accurately describing their experience with the version of the product or technique that is before them.
And that is why time honored phrases such as De gustibus non est disputandum were invented.

SeeYou190It is hard to believe that the decision to set my layout on a specific day in 1954 would be someone else's hot-button issue
We told you it should have been 1953!
I find on FB when people challenge me on a method of doing something, which seems to be commonplace on some sites. I just say to them "do it your way then, I was just offering up one method" and that shuts them down pretty quick. It's like arguing about what guitar strings to use, there is no such thing as personal taste or choice to some people.
I dunno where to begin . . .
I try to glean through the 'helpful' advice and determine who has actual hands-on experience with the topic under discussion. Watching somebody else do something on a YouTube video doesn't count. The technical term for this is bona fides; the casual term is street cred. You either got it or you don't, and it's pretty easy to spot.
BTW, I avoid white beaded styrofoam sheets because they tend to crumble like granny's dry cornbread. [Comment removed by moderator]

BATMANI got some pretty nasty comments and PMs telling me I was an idiot
I have received so many bitter private messages.
It is hard to believe that the decision to set my layout on a specific day in 1954 would be someone else's hot-button issue that inspired them to sit at their keyboard and write a manifest about how stupid I am.
I only use the information I get from the masses as a starting point. There are too many forks in the road to take the first one someone suggests.
The masses are programmed on what to eat, how to handle their finances, which one of the 4500 religions or what Diety to follow. It all stems from not educating yourself. Critical thinking is key to success. Take suggestions and break them down for yourself and do what you want to do.
When the stock market crashes as it always will from time to time, the masses panic while a few of us see lots of opportunities. Eating more than your body needs to sustain itself presents a long list of issues. Using debt to "have it now" makes you half as wealthy at retirement than if you just save up for it in the first place. You can study the Bible or you can study religion, which of those gives you a better understanding of humanity and the world we live in?
I never have a problem admitting I am wrong, those that are imprisoned by vanity will defend themselves to the end even if they know they are wrong. I built my current layout 14 years ago using open grid, foam and spline. I got some pretty nasty comments and PMs telling me I was an idiot. I think it worked out quite well and I learned a lot.
Change is how we grow and make things better, but that requires the same kind of rational thinking that protects you from buying your friend Larrys hot stock tip.
SeeYou190 I think the root cause of so much misinformation is the self-appointed-know-it-alls are too afraid to admit that they do not know everything. The situation has become measurably worse in recent months. So they post replies on subjects they know little about, people assume they know what they are talking about, then the incorrect information gets repeated. I do not know why some people... 1) Have a hard time admitting they do not know something. 2) Have a need to respond to threads where they have little knowledge. 3) Think that people who use different approaches are wrong. 4) Cannot admit when they are wrong. I come to online forums to learn. I do not know everything, I might not even know much. When I do respond with knowledge, it is usually based on experience I have gained from building 6 previous model railroad layouts and helping on many others. I do not repond with information I learned just from reading about other people building their layouts. I never trust a know-it-all that does not share pictures of what they have built. If you want to convince me, show-me. Maybe I should move to Missouri. -Kevin
