I am about to start a reasonably large layout. My surface will consist of 5/8" plywood, on top of that 1" of foam board, and on top of that 1/2" sound board. This will give me 1 1/2" of depth so I can sculptor out streams, gullies, etc. I plan to ballast all of the track. I don't think I need track or road bed for its sound deadening properties.
My question is, even though I am ballasting, would the added height of the track-bed make it look more realistic? If you recommend track or road bed, let me know which one you use. I am using Gargraves track.
Thanks much for any and all input.
