To make this, I grabed everything that I could find in my house. This includes cardboard hunks, black paint, and even trash bags to simulate the darkness and enclosed nature of a tunnel.
As you can see pitch black. This will provide the whole "light in the tunnel" effect with ease.
I also added two extra fossils on the layout. These two are seen as a locomotive's headlight lights up the right tunnel.
