Project Overview & Impact
Thornton Junction installed a new interlocked connection between the CN and UP/CSX subdivisions in the southwest quadrant of the crossing. As part of the project, the team installed upgrades between the area near 168th Street and State Street.
Previously the UP and CN tracks crossed each other but did not connect. Due to the lack of a connection, trains could not switch from one line to the other. The new connection allows trains to switch between the lines and provides increased flexibility for dispatchers routing trains throughout the Chicago Terminal District.

Project Benefits
The Thornton Junction Connection improves regional rail by enhancing connectivity and flexibility in the system.
