BOSTON — Seven MBTA employees — six former and one current — were indicted in federal court Thursday and charged with a sprawling scheme in which prosecutors say Red Line track inspectors sat in the Cabot Yard breakroom instead of doing safety inspections, ran a private-car repair shop out of the yard's garage, and clocked in for overtime shifts they either slept through or skipped entirely.

The seven were charged in a superseding indictment on charges including conspiracy to falsify records, conspiracy to commit wire fraud, wire fraud, and false statements, according to the U.S. Attorney's Office. Some counts carry up to 20 years in federal prison.

The fake inspections

Between January 1 and October 16, 2024, prosecutors allege that Red Line track inspectors falsified their inspection reports rather than actually inspecting the Red Line.

MBTA-issued cellular phones with an app called MaxTrax were supposed to record whether each inspection was completed. Instead, inspectors allegedly:

Falsely extended the duration of their reports to look busier than they were
Copied train numbers off the internet to plug into their reports, rather than actually riding the trains as required
Reported inspections as complete while they were sitting inside the Cabot Yard breakroom, prosecutors say

The scheme was allegedly overseen by their supervisor, Brian Pfaffinger, 48, of Marshfield. Inspectors Ronald Gamble, 63, of Dorchester, and Magda Trinh, 45, of Avon, allegedly instructed subordinates Jensen Vatel, 43, of Brockton, and Nathalie Mendes, 54, of New Bedford, to inflate report durations to avoid scrutiny from senior MBTA officials.

The Cabot Yard breakroom wasn't the only misuse of MBTA property. Prosecutors say the yard's large garage — nominally an MBTA facility — was being run as an unauthorized side business, with Gamble, Vatel, and two others, Danny Barbosa, 37, of Dorchester, and Matthew Leonard, 37, of Easton, allegedly working on private vehicles during MBTA work hours.

Pfaffinger, the supervisor, is accused of knowing about it — and using it. In one particularly on-the-nose sequence: in July 2024, Pfaffinger notified his subordinates that multiple sections of Red Line track had "serious defects." Ten days later, according to the charging documents, Pfaffinger requested that his subordinates use their workday to work on his personal vehicle.

## The overtime fraud

Meanwhile, prosecutors allege, Gamble was submitting overtime sheets directly to MBTA payroll — sheets that falsely claimed he and his colleagues (Trinh, Mendes, Vatel, Barbosa, and Leonard) had worked overtime shifts.

Instead, according to the indictment, the overtime shifts went like this:

Some workers didn't show up at all
Some showed up hours late
Some showed up at the start of the shift, used the MBTA hand-scan clock-in, then disappeared for hours — sometimes to sleep in their vehicles — before returning to work

Gamble allegedly submitted overtime sheets even for workers he knew hadn't completed their shifts, using the fraudulent overtime to compensate his colleagues for the private-vehicle repair work they were doing in the garage. Pfaffinger, as supervisor, allegedly approved every falsified time sheet.

The seven charged

Brian Pfaffinger, 48, Marshfield — supervisor
Ronald Gamble, 63, Dorchester — track inspector
Magda Trinh, 45, Avon — track inspector
Jensen Vatel, 43, Brockton — track inspector
Nathalie Mendes, 54, New Bedford — track inspector
Danny Barbosa, 37, Dorchester
Matthew Leonard, 37, Easton

Pfaffinger, Gamble, Vatel, and Mendes were previously indicted on May 22, 2025, and arrested a week later. Trinh, Barbosa, and Leonard were arrested Thursday morning and appeared in federal court in Boston.

The bigger picture

The MBTA has spent the last several years cycling through leadership after federal safety violations, missed inspections, and derailments. What Thursday's superseding indictment describes is not a paperwork error — it's an alleged, months-long conspiracy in which the people responsible for making sure Boston's Red Line was safe to ride were, prosecutors say, using their MBTA hours to run a car repair shop and their overtime to sleep it off.

The announcement was made by U.S. Attorney Leah B. Foley, the U.S. Department of Transportation's Office of Inspector General, and the U.S. Department of Labor's Office of Inspector General, with assistance from the U.S. Postal Inspection Service and the FBI.
