Chemical plant
McHenry station consists of one platform and two tracks. One track is used by revenue trains while the other is used as siding for out-of-service trains. The tracks continue to Barnard Mill Road in the Village of Ringwood, Illinois at the Dow Chemical plant, where the Union Pacific McHenry Subdivision ends. The tracks were pulled up between Richmond, Illinois and Ringwood in 1980 when service was cut back. However, UP left trackage for local freight trains that served industries in and around McHenry. The final local freight train on this line ran in 2006, and the line has been Metra-only ever since.
