Finally put the first bit of cork down on my layout.
Currently The layout is just a 5x9 homebuilt ping pong table with two 5x4.5 panels of double layer foam. I bought the table from the daughter of the builder who was a carpenter and built it in the 60's. Very sturdy. I've been experimenting with various bits of foam, bridges and ez track to mock up different ideas. The pic below shows it before I started messing with all that. I've also pulled the table a bit away from the wall nowso there's about a 2 foot walkway all around. Tight, but now I can reach everything.
I drew out this plan on paper.
Then a member of Model Train Forum turned it into a rendering. The lower level oval will have curves around 25" or 25" and an upper level 22" curves. Each will have half the center area for sidings and such and will be connected by a long incline.
This rendering is close but a bit different than what I plan to do. Most notably, the front/left tunnel won't start until just before the switch. Will give me a much longer visible run for the lower track
You bargain hunters will appeciate that I puchased all the foam board (most of it in full sheets) I could possibly use for the table and terrain for just $30. Got it on Craigslist in a surplus batch from a contractor.
never using cork or insulation before, i will ask, is the cork even needed with the foam on the table? or is it an atheistic thing?
It is partially an aesthetic choice to have a raised cork roadbed, but it's also about sound contol.
Hard, extruded polystyrene foam is not particularly quiet. It's actually surprisingly resonant, though two glued layers on top of a plywood surface like I have is alot less resonant than the single layer of foam on a frame that some folks use.
I do think that the soft foam roadbed that is sold is probably alot more sound absorbing than insulation foam.
Even if it wasn't needed though, I'd put down some kind of roadbed just for looks.
Yes, the roadbed does help for looks. Probably the main reason I use it. Anything you can do to get away from the perfectly flat/totally unnatural look of the tabletop. Plus you can vary it - by going to thinner roadbed (or none at all) for little-used sidings. I used N-scale cork pieces for my sidings and will in the roundhouse area. To be fair, I say my setup is pretty quiet but that's completely subjective. Noise is not a big factor with me, whatever noise I'm getting doesn't seem intrusive or annoying. I had cork on plywood for my first layout, and I can't tell the difference - I just prefer working with the foam roadbed. Great deal on the foam insulation!

Got a question about my curve measurements. This weekend I did a bit more figuring and laying out (though no additional roadbed yet). After laying out the position of the far left switch it appears that to clear the other line, the upper left curve of the lower loop main line (which will be hidden by the mountain) will be 22" while the other three curves of the lower loop will be ideal 26". How limiting is a 22" radius as far as what you can run? I think I've allowed for enough overhang of cars passing around it. I know it doesn't look as pretty, but it will be mostly hidden while the visible areas will have the broad 26" curves.
