At the TMB club we just completed laying a few thousand feet of cork road bed and track. As our curves are all custom radii we create the sub-roadbed using special protractors to scribe the center lines of our curves. Once in place, lay the cork lining the inside edge with the scribed line and staple in place. The benefit here is that the center line of the cork lines up with the center rail of the track.

Instead of a cork roadbed, I put an entire sheet of cork on the platform.  Since I have traditional 0 gauge and 027 tubular track for 2/3's of my layout, I really don't care about a raised road bed.  I get two benefits from this:  First, the train noise is significantly reduced.  Two, I can use small nails, brads, and staples to affix lights, signs, billboards, and other accessories without drilling or using glues.  This way, I can change things quite easily as the cork will repair itself once the pins are removed.  As for tracks, I use small screws that will not penetrate below the cork that are also cushioned against the track with a small amount of flexible caulk.  This seems to hold the track down quite nicely without penetrating into the platform to create vibration and noise.

With the cork, I can cut green felt and pin it down where I want grass, cutting around the track about an inch from the outer rails.  Some double-faced tape can be laid in that gap to which some fish aquarium stones are placed and then glued with a mixture of white glue, water, and a drop or two of dishwashing liquid.  I realize that the stones are larger than scale.  But when running traditional toy trains with accessories that are not truly scale to begin with, it really doesn't matter to me that much, especially with tubular track.  The illusion is still there.

I'm just in the process of doing this on my new layout.  My base is 1/2" QuietBoard over 3/8" plywood (the QB is painted earth brown).  I am laying Midwest cork roadbed down by pushing 1/2" 19 gauge brads through it into the QB with a pair of needle nose pliers.  The brads push in fairly easily and I can pull up the cork any time I want and reuse it, since it's not glued down.  Works really well.  BTW, I laid out my track and I'm now putting the cork under it, following the track.  Works very well.  With the pliers, I can reach between ties and bury the brads so they are not visible.  No wetting of the cork either - I did O31 curves with no problem using the split pieces.

I lay the track out, than with a pencil I mark each side of the track. Next I remove the track in large sections and place it out of the way. Track marking can go very fast depending on the size of the layout. You than mark a dash paten ------ in the middle of the two outside lines. You than work off the dash marks with half a piece of cork at a time. I use staples to secure the cork to your wood or whatever you are using for your table top. Any staples that are not driven all the way in can be tap in lightly with a hammer. This is fast,easy. The staples are easy to remove so you can reuse the cork over and over. Even if you ballast your track the cork can be used again.

I place the track where I want it, then use a sharp pencil or marking pen and trace a mark on the table top surface under the center rail between ties, using the center rail as a ruler.  I only do it every 3 or 4 ties, and it goes quickly.

 

Then I remove the rail and line up the inside straight edge of the cork with the trace marks I made and staple the pieces in place.  I have a plug in power stapler that I bought at the local home store, which was reasonably priced.  I use 3/8ths inch staples.  It holds the cork in place until I lay the track on top of it.  Very easily removed if you want to tweak your design.  I use a light hammer on any staples that are sticking up.

First of all, my wife and I have taken down more than a dozen layouts for clients for whom we've helped dispose of their estates.  The idea that used cork is recoverable is, well, ....unknown to us.  Staples, nails, drips and drabs of any adhesive....it doesn't matter.  More often than not, 'old age' of cork....it dries out and gets very brittle and crumbly with time.  The binder in the cork...that gives the ground cork its flexibility...has volatiles that simply lose their mojo after awhile.  Give a fresh box/piece of cork the nose test sometime.  Then, if you have a very old piece of cork roadbed lying about, give it the nose test. 

 

That said, we (LHS) tell our customers to put the cork down with contact cement...THIS stuff:

 

Contact Cement Link

 

Here's what we say...

 

1. Lay out your track on the subroadbed...plywood, homosote, etc.

2. Mark the outer edges of the ties....it's faster and easier than getting under the center rail with a pencil, Sharpie, ....whatever. 

3. Take the track up and mark the center line...a point between the tie edge marks.  A simple piece of cardboard the width of the ties and a center mark on it makes the job go fast....and is even something the kids can get involved with!!

4. Connect the centerline dots/marks to make a continuous smooth line.  THIS SHOULD BE DONE WITH A BLACK SHARPIE ON SIMILAR PEN BECAUSE IT IS CRITICAL TO LAYING THE CORK.

5. Take your cork strips and separate them along the center cut.  Lay them out UPSIDE DOWN on sheets of newspaper.  Lay out enough to do several feet of track at a time.

6. Get some of the Weldwood green-can contact cement linked above.  It's the NON-stinky stuff.  It's water-based.  You can do this job in your basement/attic/...railroad room, and you don't have to put on a respirator mask!  Yes, it's not as 'gippy' as the red-can, usual contact cement, but for cork roadbed it's the cat's meow!

7.  Using a cheapie brush, coat the bottom of the corks strips and the sub roadbed on either side of the center line (to just beyond the tie edge marks....not necessary to be fussy about this).  The dark black centerline should show through the cement coating.

8.  As per the cement instructions, let it all dry until it's tacky to the touch (about 20 minutes or so) and no 'wetness' remains.

9. Pick up a half-strip of the cork and, starting at one end, lay the squared edge along the centerline, lightly pressing as you go.  I say 'lightly', because if you EVER want to re-adjust your cork, NOW is the time to do it, and the green-can stuff is not so grippy at this point that you can carefully pull the strip back up to re-align it.

10. After you've laid a few half-strips on one side of the centerline, lay the half-strips on the other side, simply putting the squared edges together as you lay the second set.  STAGGER THE JOINTS...as others above have instructed/suggested.  This is especially important on curves.

11.  And, regarding laying cork on curves....   We suggest laying the INSIDE half-strips along the centerline first.  Two reasons: They will require the sharpest bending, and, once down, will simplify laying the outer half-strips against them.  You may have to apply a bit more pressure initially as you lay the cork on a curve.

12. Once both sides of the cork are down....and you're happy, happy, happy so far!...follow with rolling the top of the cork with some sort of roller to ensure a good bond.  You can buy laminating rollers at hardware, home improvement stores.  A rubber roller artist's brayer (inking roller...Speedball brand) is what we sell and use.

13. When laying cork under switches, the easy way is to get cork sheets and cut and lay them separately.  If you prefer to cut and blend the cork strips through the switch zone, first lay down the outer strips for the diverging routes.  Then cut, fit, and glue filler piece(s) afterwards. 

 

That may sound complicated, but believe me, it goes really fast once you do the first few feet.

 

BTW, if you insist on trying this with the regular 'red-can' contact cement, all bets are off, you're on your own, and rots-o-ruck, pal. 

 

FWIW.

I have always found cork roadbed or Woodland Scenics foam roadbed to be very easy to work with.  It easily follows whatever path you choose and can held in place by nails, screws, glue, spray adhesive, or whatever your favorite method might be.  I also agree that reusing it is not impossible, but only if it is not too old and become hard and brittle.  I wouldn't plan or reusing it, but if you are consider it a bonus.
