Rush hours in the Loop are gonna be a little tougher in a couple of weeks, as the Washington Red Line stop ceases operation in preparation for Block 37 Superstation construction. Starting October 23, there'll be no train access, and the Blue Line tunnel will also be closed (transfers will only be available at Jackson). The CTA says work is "expected" to finish in Fall 2008. For more details, see Tony Coppoletta's run-down on the shut-down.
