I just wanted to get some opinions from all of you. My next project that I would like to work on for my indoor layout is to make a mountain with a tunnel. I bought two of Aristocraft's double track tunnel portals. When I placed the tunnel portals to check for clearences, there seemed to be extra space above the trains, almost like the tunnel portal is too tall and kind of looks unrealistic. I wanted to get your opinions and see if you agree. I was going to cut an inch or two off the bottom of the tunnel portals to lower the clearence but I wanted to see what you all said first. Below are the pictures to show what I'm talking about.
