The Abandoned Winston Tunnel (CGW) near Galena Illinois. I had done a lot of reading about this tunnel, the men that built it, the trains that ran through it, and the interesting ventilation system it utilized. Standing at the west portal marveling at the fan house and all the work it took to make this tunnel, in the distance you could hear the trains blast their horns as they ran along the Mississippi on the BNSF Route to the Twin Cities. If you closed your eyes you could swear that the line was still in service.
