Glenwood to Chicago Heights - B&O Chicago Terminal
The Baltimore & Ohio Chicago Terminal was a switching road in the Chicago area that was absorbed into CSX in the 1980s.  While some segments are still in service, this segment was likely abandoned in the 1980s after the CSX merger/consolidation.  

The right of way in this area will eventually be incorporated into the American Discovery (bicycle) Trail.
This bridge is in Glenwood, IL on the former Baltimore & Ohio Chicago Terminal (later CSX), a switching line south of Chicago.

This line was likely abandoned when CSX obtained trackage rights on the parallel Union Pacific (which was originally the Chicago & Eastern Illinois and later the Missouri Pacific).
