Tunnel

After finishing the main line run and ensuring my locos run on it smoothly, I built the tunnel that will eventually run through the great Silver Mountain. I used cardboard-covered foam sheets that I found at my local hobby store (unfortunately I don't know the name of the material but they were just a few dollars for a large sheet). The material was really easy to cut and provided a sturdy frame for the tunnel. I used my trusted hot glue gun to attach the pieces. After the walls and portals were in place, I covered the tracks with paper and painted the interior walls black so they would look right. Finally I attached the ceiling pieces which I had pre-painted on the side. I used ready molded portals from Woodland Scenics and they look really good.
