Roadbed for yards?
Author: TEEKAY

My mainline has cork roadbed underneath, is it realistic to have individual cork roadbed underneath my yard operation? Or is it more prototypical to have none?

try cork sheets for yard tracks,,would look more realistic.

I agree.

You can buy thin sheets of cork from Micheals or Hobby Lobby. Takes several several heavy books to flatten the rolls of cork, but it's the way to go.

The Engineering Standards and in many States the Public Utilities Commission safety standards call for a level walkway alongside yard tracks: the body tracks and leads.
Anywhere an employee is likely to need to walk alongside a cut of cars, to step back to clear a moving car, or back in the day to get on or off moving equipment.
So yes, a flat sheet of cork is good.
And the ballast size should be small.  We used 3/4" rock in walkway areas and 1-1/2" on the main lines, later up to 2".

Remember to have your Main Line a little higher than the yards.  Over the years little or no ballast is added to a yard, but the Mains get ballast regularly, hence they end up taller.

Or Homasote. That's what I use. Holds spikes and track nails better.

I've used the Woodland Scenics Foam sections for yards.  It's easy to handle and works well for me, but I also use the Woodland Scenics Foam roadbed.

Doesn't matter which material mentioned above that you use for substrata, you will need to add some kind of ballast material between the tracks and between the ties to bring the ground up to the base of the rails.  In the above posted pics, https://www.trainorders.com/discussion/read.php?3,5201994 I used sand.

It is if you are modeling the German Railways DBAG!

Here is an image for using 1/16" cork under the ties in the yard to get a low profile above the subgrade.

OH yes first time building a layout friend helped me that had done it before so mine got installed with normal main line width resulting in several hours of work filling in between them. Oh how I wished for sheets instead each track is 12ft amd six of them.

I haven't examined the cork sheets sold at Hobby Lobby, but here is a source that might be more economical.  I don't know if Hobby Lobby's cork sheets are packaged as a roll, but these are absolutely dead flat 2' x 3' squares so there is no fighting the cork to counteract the rolled-up memory to get the cork to lay perfectly flat. I used the 1/4" thick cork version for my HO layout.    This cork will be the main base for the yard.    More heavily used yard tracks (yard lead, departure tracks) will have n-scale cork roadbed laid on top of the cork sheet to get a bit of elevation.

BTW - Sheet cork is waaaay easier to work with vs. Homasote.  Cuts like butter with a sharp utility knife and there is no messy dust to contend with.   I use clear adhesive caulk to lay track.   Ground throws are attached using wire nails that are long enough to extend thru the cork and anchor in the plywood sub-roadbed.

This looks like a great way to go. One question though: looking at their site, it looks like you can only purchase these in boxes of 16 sheets (for 1/4") There's no way I'd need all of this for my N scale layout. Were you able to buy individual sheets or were your yards big enough to justify buying the whole box?

Good tip tho. Thanks for the post.

I've never used cork except for Midwest cork roadbad under mainline parts..  For large area's like yards I MUCH prefer sheet Homasote.  I had Home Depot cut it into one or two long sheets so I could fit it in the car.  Then I used a utilty knife if I needed to cut it further - no dust that way.  It takes a few passes so no big deal there.  I save my butter for toast!  ;-)

I've used Homasote on my previous 3 layouts and like it so much for yards, I'm using it again on my current layout.  It's so easy to lay track.  Draw centerlines, and track is down instantly with track nails or ME spikes; no waiting for caulk to cure.  If track needs changed, I can simply pull the nails or spikes out with needle nose plyers and relay.  No peeling track up from the caulk.

I highly recommend Homasote.

Cheers,
Jim

They don't sell iidividual sheets.

I bought a box of 1/4" and used it over the entire layout.  My 10' x 13' around the walls plan used all but about 3 sheets.  Mainline will have the usual HO-scale cork roadbed laid on the 1/4" flat cork sheet to get the vertical separation from sidings (N-scale cork roadbed) and industry tracks (no roadbed, track laid right on the cork sheets).

You might be able to find individual cork underlayment sheets at a flooring store, or maybe a flooring contractor will part with a few sheets if that's all you need.

By the way, the hand-laid yard track looks great!  And i like the idea of PC board ties and soldering.  Looks to produce a more consistant track gage.

I bought cork sheet in different thicknesses and various widths/lengths from Bangor Cork.  https://www.bangorcork.com/
You can also email them at sales@bangorcork.com

Good luck,

I laid a yard on Homasote and used no ties. Just spiked the rail in guage directly on the board a little paint and thin ballast with a few tie butts exposed in the dirty ballast and debris. Most older yards have not seen ties for decades.
