Project Overview & Impact
Prior to completion of this project, freight trains destined to Barr and Blue Island Yards to the east waited at this location for access to the yards, creating congestion on the main line tracks. This project involved construction of a third main line along the Indiana Harbor Belt, upgrading of some existing track at interlockings, a new rail bridge over 127th Street and associated signal work.
The new third main line track now provides additional capacity for trains passing through the area to proceed around trains waiting for yard access.

Project Benefits
The Third Mainline – 123rd Street to Cal Sag Channel improves the rail system by providing modern infrastructure that provides additional capacity and efficiency.
