MTA / NYCT

Products: n/a. Risk band: Elevated   RobotRisk index 15.7/100 (incidents/exposure, time-weighted) · 55th percentile of 62 other companies.

Analyst brief

MTA / NYCT's record contains two entries: a May 20, 2026 subway signal system fault disrupting rush-hour service (severity 2) and a July 26, 2021 Queens Boulevard Line signal system outage (severity 3). Both events involve signal-system failures rather than collisions or injuries, producing an index of 15.8 and a 53.2nd percentile within the other category, in the elevated band. The record is press-driven and spans nearly five years between the two entries, indicating recurrence of the same failure type (signal-system outage) rather than an escalating or diversifying pattern. The gap between events does not support a claim of an accelerating trend.
