Here's an idea for tunnel liners. They're flexible, not necessarily fully removable.
On my previous layout I had side access to the tunnel interior (vs. from underneath). But due to viewing angles I needed a liner for both sides of the track. SO I came up with this solution.
I used heavy duty aluminum foil, crumpled and painted then arched over the track and hot glued to one side. This way I could lift up the liner to rerail or retreive any equipment stuck in the tunnel, then bend it back down into place afterwards.
First I crumpled the foil to add a rocky look. Then I painted the foil with a can of black spray paint. After the black had dried I added shades of light gray. You could also use that texture paint from the craft store...the stuff that sprays out little colored flecks. They make one with a nice granite color palate of black, white and gray. But really I think just the basic black with a dusting of grays or your base earth coat, is best.
Also, be sure to spray the secondary color 'into' the tunnel. What you want to acheive is a shadow effect from the black. SO an observer looking into the tunnel sees mostly your base rock color with black shadows behind any crinkles...uh, rocks. Just make sure the black coats the foil well enough to hide any shiny edges or points.
