Modifies provisions relating to railroad crossings

SB 972 requires all new at-grade railroad crossings built after August 28, 2026, to include advanced detection systems that identify pedestrians, vehicles, and wildlife using sensors and AI. These systems must analyze risks in real time, send alerts to train crews, and integrate with existing safety protocols. The Missouri Department of Transportation (MoDOT) must develop standards for these systems, prioritize high-risk crossings for upgrades, and create a grant program to fund installations. Rail operators must annually report system performance data to MoDOT, which will evaluate effectiveness and submit biennial reports to the legislature. The bill directly affects new railroad construction projects, MoDOT, and rail operators in Missouri.
