MTA watchdog audit sparked by 2024 explosion finds transit agency had widespread substation maintenance failures

The MTA Inspector General’s office found “serious gaps” in the transit authority’s maintenance and oversight of its substations in a new audit the agency watchdog released Thursday that was sparked by a 2024 explosion at one of the essential power conversion facilities.

The audit found that MTA NYC Transit’s Substations Group did not conduct 19% of required maintenance checks at the facilities during the year of the explosion. The incident occurred at the State Street substation and caused a power outage that stranded over 4,000 riders on trains in Downtown Brooklyn.
