CSX yesterday announced it has removed the historic Forest Hill rail diamond crossing in Chicago, a project that was designed to reduce congestion in one of the nation’s busiest freight corridors.
Created through agreements between railroads dating back to 1891 and formalized in 1914, the Forest Hill diamond had long required trains to slow or stop before entering the crossing, which created chronic delays across the Chicago rail network, CSX officials said in a press release.
As part of the Chicago Region Environmental and Transportation Efficiency Program's 75th Street Corridor Improvement Project, CSX and its project partners removed the diamond, eliminating a more than 100-year-old grade crossing. The diamond project was completed in mid-November 2025.
With the project now completed, trains can move through the area without stopping. In addition, the reconfiguration reduces long-term track and signal work, enhances intercarrier operations and reduces noise in adjacent neighborhoods, CSX officials said in a press release. A CSX video of the project is available here.
