Tunnel Interior

[OldGuyHO]

As said before, you only need "scenery" for the tunnel openings. Make a skeleton, use crumpled aluminum foil as "rock" to cast the tunnel openings (cast the outside of the aluminum foil, once dry, strip off the foil and use the cast piece after painting it black/grey/as you want).

My tunnel portals are already in place and plastered into the mountain. That would be way to much work to change them out for a bare rock wall entry.

I'm pretty sure he's talking about the first 12" or so inside the tunnel .... the crumpled foil gives it that blasted look as if it were dynamited

On my last layout, I lined the first 24" with Al. foil that was painted black, and taped to one side of the roadbed to keep in place. If I needed to get to a derailed piece of rolling stock or stalled engine, I would just use the taped down portion as a hinge, and roll the foil as a unit over onto that edge, move the car(s), engine and then unroll the foil back down.
