Ballast for Peco On30 flex track on cork roadbed?

I used roofing shingle grit on my ME On30 track poured from a shotglass size plastic cup between the rails and outside the rails. Brushed and tamped in place and shaped with a 1/2" wide cheap paint brush.  Wet water/Elmer's White Glue to fix in place.

That looks really good! (Perhaps too good for a narrow-gauge shortline railroad!)

Really nice.  Where do you purchase roofing shingle grit sir?

Try a large building supply distributor.   

I have an extra 5 gal. bucket sitting in my garage.  be expansive to ship however

Not all NG RRs were poor...mine is well run, well maintained, and profitable. (I charge visitors for their beer and wine...)

I used "Starter Chicken Grit" bought at a local feed store.  I dyed some dark and mixed it so I have three batches of light, dark, and a mix of both.  This way I can use it where traffic demands.  As for most of my Utacolzona On30, I also put down a lot of dirt, coal, & grass effects.  Everything is glued.    Dennis
