NEW YORK (1010 WINS) — Gov. Kathy Hochul on Friday announced the findings of an investigation into what caused the widespread power outage of multiple MTA trains on August 29.
According to the report, two independent engineering firms – HDR and WSP – have determined the root cause and found that the outage was caused by human error.
"On the night of Sunday, Aug. 29, service for subway riders suddenly and unexpectedly shut down, and immediately following the disruption, I directed the MTA to investigate the cause. The teams worked expeditiously to identify the source of the problem and recommend improvements.
I am directing mitigation steps to ensure riders are not interrupted by these causes ever again," Gov. Hochul said.
As a result of the investigation, Hochul is directing a full review of operation control centers across the entire MTA to identify and mitigate any other potential weaknesses.
“New Yorkers deserve absolute confidence in a fully functioning subway system, and it is our job to restore that confidence. I am also directing the MTA to review all operation control centers across the entire system to identify any further potential weaknesses and provide assurance in preventing a situation like this from happening ever again,” the governor added.
The reports revealed the loss of power at the New York City Transit Rail Control Center was caused by a manually-activated power-off switch on one of the building's power distribution units.
Preliminary indications suggest that the emergency push button might have been accidentally pressed, since a plastic guard that would prevent accidental activation was missing.
Failure to restore power for more than an hour appears to have been the result of internal organization and process flaws, with existing organizational maintenance structures at the RCC in need of revision to prevent similar incidents from happening again.
The firms investigating the incident also found that the effects of the incident were exacerbated due to the RCC's lack of a power distribution monitoring system. Such a system would provide visibility of the status of key electrical components in the power distribution system.
"The report tasks the MTA with immediately reorganizing how we maintain and manage key systems that support the RCC. The agency will also install additional cable connections to improve power redundancy in the building, as well as a more comprehensive Building Management System that will provide detailed visibility into the status of the building's electrical distribution, mechanical, and security systems," MTA Acting Chair and CEO Janno Lieber said.
