An Act relative to Hot Box Detectors

This bill requires the installation of hot box detectors, which are devices used to detect overheating train wheels, every 20 miles along any line where passenger trains operate in Massachusetts. The law mandates that these detectors be included in all new construction projects and must be installed on existing rail lines within one year of the bill's passage. This change directly affects railroad operators and the state's transportation infrastructure by updating safety standards for passenger rail service.
