MBTA

Products: n/a. Risk band: Elevated   RobotRisk index 34.0/100 (incidents/exposure, time-weighted) · 97th percentile of 62 other companies.

Analyst brief

The record contains two entries tied to the same underlying event: a 2022 fatality in which a Red Line rider was dragged to death after a door-control-system short circuit, and a 2025 entry recording the resulting $5 million regulatory settlement, both severity 5. This is a single incident followed by its regulatory resolution, not two independent failures. The maximum severity rating on both entries reflects the fatal outcome and the settlement's formal regulatory disposition. Index 34.3 and the 96.8th percentile place MBTA in the elevated band, driven by this one high-severity event and its extended regulatory tail.
