Siegel Oil is located at 13th Ave. and I-25. It is the end of a Colorado & Southern line that used to run west to Lakewood and the Federal Center. The line crossed the BNSF/UP shared trackage mainline at a 90 degree angle, serviced the Public Service power plant, crossed the Platte, and proceeded west. When the Auraria College campus was developed it disrupted access to the line. A turn out was added that passes through the backyard of a business and makes a sharp 90 to the west.
