2023 Triennial Audit - Audit Analysis by Grouping

The Department of Public Utilities (“DPU”), as the State Safety Oversight Agency for rail transit (subway lines) in Massachusetts, has completed a Triennial Audit of the Massachusetts Bay Transportation Authority’s (“MBTA”) Public Transportation Agency Safety Plan and its implementation. The Triennial Audit is a requirement of 49 C.F.R. § 674.31 and 220 CMR 151.10(2).

Audit Analysis by Grouping

This section of the Triennial Audit report provides a summary of the results from each of the audit Groupings. Each section provides the following:

• Name of the Grouping;
• Scope;
• Positive Observations;
• Opportunities for Continual Improvement;
• Recommendations; and
• Findings.

Each of the Findings requires a CAP. The Recommendations require at least a response from MBTA and, if MBTA determines appropriate, a CAP. Opportunities for Continual Improvement present areas where MBTA meets the goals of the ASP and can enhance their program to increase safety.
