Introduction

Following an investigation into a fatal accident on August 4, 2023, in Great Barrington, Massachusetts, the National Transportation Safety Board (NTSB) has recommended that railroads implement collision avoidance technology on roadway maintenance machines.

Background of the Accident

The NTSB’s investigation focused on an incident that occurred on August 4, 2023, in Great Barrington, Massachusetts, where a maintenance machine struck and killed a worker. The investigation revealed that the machine operator lacked safety devices beyond a wide-angle mirror for hazard detection.

Investigation Findings

The investigation uncovered failures in communication and oversight. Specifically, the roadway worker-in-charge was not fully informed of the work’s scope, resulting in an inadequate safety briefing and the absence of a second qualified supervisor. The NTSB determined that improved supervision and communication would likely have mitigated the risks associated with the operation.

Safety Recommendations

As a result of the investigation, the NTSB issued six new safety recommendations. These recommendations address unsafe machine operation, the implementation of collision avoidance technology, and the need for enhanced Federal Railroad Administration oversight of railroads with subpar safety performance.

Key Issues

The primary safety concern highlighted by the investigation was the lack of adequate safety devices on the maintenance machine. The machine operator’s reliance on a wide-angle mirror underscored the absence of advanced technology to detect potential hazards. Additionally, the NTSB emphasized the importance of clear communication and robust supervision to ensure worker safety.

Conclusion

The National Transportation Safety Board’s recommendations stem from an investigation into a fatal accident in Great Barrington, Massachusetts, on August 4, 2023. The recommendations focus on improving safety through collision avoidance technology, stronger supervision, and better communication.
