We had been meaning to get this portal for quite a while. This is in Kentucky, near Sampson. The portal has a 1930 date, clearly seen. On my other post for Hagan Tunnel, I note that the line came through here in the late 20s. This, then, may be an original portal facing, done when the road was completed (another tunnel on this line near here also has a 1930 date). The tunnel comes out in Hagan VA, where there are two wyes. The railroad was in the process of working on this tunnel. Off to the right you can see the 750 kw generator. This also an air compressor on site, to which the orange-ish lines coming off the horn things are attached to. I don’t know what this arrangement is set up to do. I know the generator is for the lights strung down the tunnel, but this has me wondering. More research! Input requested!
