Daily Trains Affected

77 Freight Trains (IHB, CSX, UP, BNSF, CN, NS, CP, Iowa Interstate)

Communities Benefited:

  • Alsip and Blue Island


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. The new third main line track now provides additional capacity for trains passing through the area to proceed around trains waiting for yard access.
