INDIANA'S INTERLOCKINGS

CHICAGO INDIANAPOLIS & LOUISVILLE/MONON

First Sub-Division

Segments now owned by CSX, some segments abandoned.

The 1981 closure of South Hammond Yard resulted in abandonment of line through Hammond. After then, Amtrak trains switched to and from former Pennsylvania Railroad line at Air Line interlocking, a short distance north of the GT Crossing.

Former crossing with Grand Trunk Western. Effective June 30, 1993, Amtrak trains and remaining freight trains began using former Grand Trunk Western west of GT Crossing. Which enabled abandonment of remainder of Monon route north of there, along with connecting former Pennsylvania Railroad line.
