Foam Or Cork
Posted by Anonymous on Sunday, July 13, 2003 6:08 AM
My Dad gave me all of his HO train set stuff New in boxes for me to make for my kids and in it there is cork from a craft shop and PECO Moulded Ballast Inlay. The Track I am using is all PECO and I am doing a 8 x 6 Layout. What is best to use??? Dad said to use the cork because the foam is too bouncy. Any opinions would be greatly Appreciated.

Your Dad is right!!
I have had good luck with cork. I usually glue it to homosote and paint it black (any color will do)
This way you are sealing the material. If you have a damp basement this will keep it from buckeling or warping.
Mine present layout has been operated on for about 20 years now and never had any problems.
Have fun and enjoy.....
If you have any more questions, please ask... this is the way I learned......

I fully agree with Rich..Go with the cork and homosote..You will be glad you did.

Cork's an excellent choice, there's a reason it's been the standard for half a century. I personally went with the Woodland Scenics Roadbed, which is lower profile than cork (1/8" high vs 1/4"), and dampens sound better, but it is about twice the price.

I use Woodlands foam roll trackbed, and I'm VERY happy with it! Very easy to use and install. 25 foot roll cost about $8 Canadian. So it's cheap too:) A lot less theb cork.

I use the woodland scenic foam. I love it. It really does deaden the sound, IMO, better than cork.

I've had excellent results with cork. It's easy to work with and does a good job.

I have used cork roadbed over Homosote with all my layouts and never had a problem with the track.

Two thoughts.
On prototype railroads, sidings are lower than the main line. Using cork for the main and foam for the sidings would allow you to simulate this height difference pretty effectively.

Second, some years ago Atlas experimented with replacing cork roadbed with one-piece rubber compound (it looked recycled). It was easy to lay and curve but because it was one piece, it didn;t have the nice feature two-piece cork does of following a center line exactly. I did a whole layout with rubber but then went off to school and that was the end of that. I assume that Atlas must have concluded that people preferred two piece cork. The rubber was also a little more expensive as I recall.

How well is the humidity controlled where the layout will be? If it is like a garage or basement in the mid-west, avoid cork and Homasote®. If it is in the dessert, or outside in Florida, where the humidity is fairly constant, it will be fine.

If you are not handlaying track, avoid Homasota® and spikes. Use foam and glue.

If you insist on Homasote®; make sure that you seal it - all sides.

Sure the Woodland's Scenics underlay is fine stuff - but Scotty here is talking about the Peco stuff which isn't any good at all - it really is foam and is truly dreadful. Oh and the Woodland Scenics stuff may be cheaper than cork in Canada but it sure isn't in the UK - so cork it is!

I'd also second that thought about sealing Homasote if there's even a hint of humidity anywhere near the layout, otherwise you could be in for some very interesting bumps. Personally I just lay 1/8in cork onto 1/2in ply road bed it works a treat, unless you really want to hand lay track with spikes - which is where the Homasote comes in.

Cork here. I'm in the process of building a layout. First in 20 years. Using foam to build scenery.

Brought to you by the letters C.P.R. as well as D&H!

Cork worked out fine in relatively dry Alberta. In coastal Nova Scotia I'm laying AMI roadbed on Foam Insulation Board. We've just come through 3 weeks continuous fog, and have a week of rain forecast. I'm not expecting any problems.
But, to answer your situation, dowling_s, sounds like father knows best [:0], even if you have the Peco foam, go withvthe cork but seal it.

"If it is like a garage or basement in the mid-west, avoid cork and Homasote®."

Although this old saw is often repeated, tests of the materials tend not to support it. Virtually all of the movement you can expect in the roadbed is attributable to expansion and contraction of the benchwork and subroadbed. Cork or Homasote aren't structural (unless you're building Homasote spline roadbed), and the change form expansion and contraction of typical 1/4" or even 1/2" thicknesses are negligible compared to the benchwork movement. The 1/2" or 3/4" plywood subroadbed moves, the 1"X4" (or whatever) benchwork moves, and the thin roadbed material goes along for the ride. When the track buckles or gaps open, the roadbed then catches the blame.

I may live in a dry climate, but my Homasote roadbed gets soaked when I build scenery and ballast track. It doesn't budge. I would endorse either it or cork over foam. Over time they are far more durable.

i would use foam olny where the track is not visable (tunnels, hidden fiddle yards, etc.) otherwise use cork, you'll have an easier with ballasting over cork than foam. its a more solid base. and takes abuse much better.
