Federal prosecutors have widened their criminal probe into Red Line track inspections, filing a superseding indictment that pulls three more people into an alleged scheme to fake safety checks and pad paychecks. The alleged misconduct, tied to work performed during much of 2024, supposedly undercut the very records the MBTA and outside safety reviewers count on to keep trains moving safely.
Superseding indictment names seven defendants
The new filing names six former MBTA workers and one current employee, according to a U.S. Attorney’s Office release. Listed in the superseding indictment are Brian Pfaffinger, 48, of Marshfield; Ronald Gamble, 63, of Dorchester; Magda Trinh, 45, of Avon; Jensen Vatel, 43, of Brockton; Nathalie Mendes, 54, of New Bedford; Danny Barbosa, 37, of Dorchester; and Matthew Leonard, 37, of Easton.
Prosecutors say Pfaffinger, Gamble, Vatel and Mendes were already indicted in May 2025 and arrested that same month. Trinh, Barbosa and Leonard, the new additions to the case, were arrested and brought into federal court in Boston on Friday.
How prosecutors say the scheme worked
According to charging documents, inspectors allegedly leaned on MBTA-issued phones loaded with an app called MaxTrax to log track checks as “complete” even when they never left Cabot Yard, as reported by The Boston Globe. Some inspection reports allegedly listed train numbers lifted from online schedules instead of from trains the workers actually rode.
Surveillance images in the case files reportedly show some of the same inspectors hanging out in a breakroom, chatting in the parking lot, or working on private vehicles inside a garage at Cabot Yard when they were supposed to be out walking the Red Line tracks. Five Linked to MBTA Charged first drew attention to the initial indictment and early reporting around what was happening in the yard.
Charges and potential penalties
The superseding indictment stacks up counts that include conspiracy to falsify records, conspiracy to commit wire fraud, wire fraud, falsification of records and false statements, along with allegations of overtime fraud, according to the U.S. Attorney’s Office. Some of the falsification and wire fraud counts carry potential prison terms of up to 20 years, while certain false statement counts come with possible sentences of up to five years. The case is being handled by the USAO’s Public Corruption & Special Prosecutions Unit.
Why this matters for riders and oversight
Safety experts and state reviewers have repeatedly pressed the MBTA to tighten oversight of inspections, and local reporting and audits have pointed to gaps in how the agency documents and responds to track defects, according to WBUR. The alleged scheme emerged in the middle of a sharp rise in overtime payouts at the T last year, which prosecutors say boosted some workers’ pay.
MBTA officials say they moved quickly once the alleged conduct surfaced and that they have cooperated with investigators. Trinh, Barbosa and Leonard were arrested Friday and appeared in federal court in Boston, local reporting shows, and prosecutors say the investigation is not over.
