SFMTA's record holds one entry: a February 2019 failure of the Automated Train Control System's central computer, which halted subway communications, severity 3. This is a press-reported infrastructure outage, a single discrete event with no recurrence in the record. Unlike other low-band entities in this set, SFMTA's percentile standing of 19.4 within the other category is markedly lower, indicating this incident places it well below most category peers on relative risk despite sharing the same low-band index value of 7.1. The record reflects a singular system-failure event rather than a systemic or repeat pattern.
