Subway service was restored Sunday hours after a power failure halted service on several lines between Manhattan and Brooklyn, officials said.
There were no A, C and F trains running between the two boroughs for more than two hours on Sunday afternoon, the MTA said.
A ConEd power failure at the Jay St.-Metro Tech station was blamed for the disruption. A ConEd spokesman said there was damage to substation equipment on Gold Street by the waterfront and crews were investigating.
The MTA said customers should expect delays on the A, C, F and G lines.
Gov. Andrew Cuomo demanded an investigation of ConEdison.
"The apparent failure at ConEd substation Sunday afternoon was completely unacceptable, affecting Brooklyn NYCHA residents and passengers on subway trains across the city," Cuomo said.
