The Sioux Falls, South Dakota USA switch yard is right next to the corner of 8th Street and Weber Avenue in downtown Sioux Falls. I when out early in the morning on Friday, October 12, 2012 and the tracks were very active at switching cars and tracks. The crossing signals were constantly going off. Right before this photo I was on the phone with my grandson Scott wishing him a happy 6th birthday.
