Benchwork Question

I've done it both ways.  The advantage to foam is that you can carve rivers and ditches or other lower than the track scenery items into it.

If you search on past threads you'll find that this is a frequent discussion and that there are many different opinions, which means there is no right or wrong answer. Generally laying a sub roadbed like Homosote or foam will deaden the rumble of your trains. Cork or Woodland Scenics' foam roadbed will accomplish pretty much the same thing. Carving foam to create below grade scenery elements is another reason cited for using foam. Foam is messy, but otherwise a little more forgiving when you cut it. And it cuts with a knife instead of a more expensive power saw. When you get right down to it, do what seems easiest and get the trains running!

  My roadbed is glued to 1/2" plywood.  It is 'cookie cutter' on 'L' Girder benchwork.  All track is elevated at least 3" off of the 'L" Girders so scenery can drop below the track level.

 I used the WS 4'' risers on my layout. They're somewhat expensive, however my layout is small and has a few bridges. If you want flat terrain, at least use 1" risers.

I was wondering if it is nessacary to lay a layer of foam for your benchwork or can you just glue the roadbed to the wood top?
