Fast Facts Explained
- "Investigations" refers to DPU Rail Transit Safety Division's oversight of the investigations of MBTA safety events.
- DPU's regulations delegate investigation responsibility to the MBTA on DPU's behalf. While the MBTA conducts the investigation of safety events, the DPU observes and participates to ensure the investigation was done carefully and thoroughly.
- "Investigation Final Reports" refers to final reports associated with safety events that MBTA is required to draft and submit to DPU for review and approval.
- The DPU may reject a final report if it does not meet a high threshold of quality and completeness; upon rejection, DPU will require MBTA to submit a revised report. The final report must be formally accepted by the DPU before an investigation is closed. Many final reports also include recommendations for CAPs.
- "CAPs" refers to Corrective Action Plans, which address deficiencies identified during investigations. DPU may also require the creation of CAPs to address safety compliance issues we identify through our inspections and our audits.
- Each Corrective Action Plan is made up of one or more Corrective Actions, each with specific due dates and items to address the safety issues identified.
- Investigation Final Reports Past Due indicates that MBTA has not submitted a final report by the due date or has not submitted a revised report following a DPU rejection by the revision due date. Count is accurate as of the last day of the reporting month.
- Overdue Corrective Actions Percentage indicates the percentage of Corrective Actions that are open past the scheduled date of completion. The percentage includes Corrective Actions with a pending MBTA request for closure, modification, or extension. Percentage is accurate as of the last day of the reporting month.
