Northbound Norfolk Southern intermodal transfer train crossing South Archer Avenue. Chicago Illinois USA. March 2008.

I took this photo near Chicago Midway Airport near South Archer and Knox Avenues. The crossing gates on South Archer Avenue just lowered a few minutes ago, and now a slow moving northbound Norfolk Southern container train will be tying up rush hour traffic on it's Journey across Chicago. The train is traveling over the Belt Railway of Chicago.
