Old Railway Tunnel, Glenfarg

This is the third time I've been through this railway tunnel and it still freaks me out. It's maybe about a third of a mile long and curves so that as the light from the entrance behind you disappears, you can only just - ever so faintly - start to see the light ahead at your exit.

Had to take the photo with the dog on her lead in one hand, and a huge Maglite torch tucked under my arm, so I couldn't hold the camera steady for the length of exposure time it needed, hence the blurred effect. I quite like that though - makes it look a bit surreal.
