I have one tunnel in particular whose first several inches of interior will be very visible to all, and I would like to know how to model the interior. What sort of structural contraptions (plate anchors, etc.), if any, would be visible? (And would these be on the walls or only the ceiling?) What about beams? What's the best way to simulate the appearance of the tunnel walls?

If they are rough blasted tunnel walls, try aluminum foil, painted pitch black.

I would go one step further: paint everything about an inch inside the tunnel pitch black. The walls, roadbed, ties, rails (except the top of course!), etc.

My tunnels are unlined but I put a coat of flat black latex paint as far in as I could reach. I will also add a small curtain in front of my access portal to block out the rest of the ambient light.

Whats really funny. Going to Home Depot and asking for flat black paint.

The girl at the counter just couldnt figure out why I wanted flat black paint, even after I told her. LOL
