This bill establishes new regulations for railroad safety in Oklahoma, specifically focusing on the installation and maintenance of hot bearings detector systems along main lines. A hot bearings detector is defined as an infrared device that monitors the temperature of train bearings, axles, or wheels to prevent overheating. The bill mandates that any entity operating a train must install these detectors at intervals of no more than ten miles on main lines, which are defined as tracks with an annual traffic of five million gross tons or more, excluding certain tourist and scenic operations.

Additionally, the bill grants the Department of Public Safety the authority to issue citations for violations of these regulations, with fines ranging from $1,000 to $5,000 for non-compliance. The new law is set to be codified as Section 104 of Title 66 in the Oklahoma Statutes and will take effect on November 1, 2025.
