Nice portals, guys. I wish I had a bigger layout so I could justify a tunnel, since I've always like the looks of trains going in and out of tunnels. Maybe someday...
How about another abandoned tunnel. This one is also in HO and depicts a collapsed narrow gauge tunnel. Layout it is installed on is a 1950's era standard gauge pike. Tunnel was built intact then crushed at the rear to simulate the collapse.
Hey folks some nice work again!
The Fox River Valley has a few tunnels, just to hide the right-of-way disappearing into a narrow closet on one side and wrapping around my work bench on the other.
