Ed, Depends on if you want a concrete, or a excavated rock liner, and if the mountain is removal to install a liner. For concrete one could look inside a prototype tunnel, and measure the height, and width of the wooden form lines left after the concrete was poured and, make mold of the same size in scale, then cast it in plaster. For rock, there is a few options that may be used alone, or together. One is to take Styrofoam, both the pink stuff, and the type that forms beads when broken. Glue them together in a size that is at least two inches larger that the size of the tunnel opening. Cut out the opening with a hot knife, next dig out parts of the tunnel to represent the various depths of rock removed. Next paint the inside of the tunnel different colors to represent the differing rock strata inside. Have other ideas about the subject, but trying to KISS.

The track makes a 90 degree bend in the tunnel under the mountain, black spray paint made the interior almost invisible, to the point that our youngest member at the time ( 16, ) put a small "hobo camp" IN the tunnel and had to install a small overhead light bulb, 18 v to illuminate it. Neat effect, the black paint made lots of stuff "disappear". Jim Lyle In a message dated 6/5/2011 1:24:29 P.M.
