Cutting and laying the roadbed
Having established the basic configuration for the major
bridges, the next step was to create and lay the roadbed.
Having had good success with this technique in a previous
layout I chose to use Celotex (also called sound board, or
Homasote, a similar product). It is easy to work with and has
excellent sound deadening qualities. The cost per sheet is
about $15. Roadbed for this section of the layout consumed
two 4’ x 8’ sheets.
Orv Dunn published an excellent article in “Model Railroader”
of May and June of 1967, “From Floor to Rail” (45 years ago,
my how time flies! That’s the year I married my wife). His sub-
roadbed was created using the spline technique. On top of this
he glued roadbed created from Celotex/Homasote using the
