Gov. Andrew Cuomo on Friday called for an investigation into the equipment failure that led to delays along the MTA subway system in New York City.

The investigation would be conducted by the Department of Public Service, Cuomo said in a statement, into the equipment maintained by utility Con Edison.

“The loss of power due to a Con Edison equipment failure during the morning rush hour caused a cascading effect and impacted the lives of thousands of commuters,” Cuomo said in a statement.

“Simply put, this was completely unacceptable and I am directing the Department of Public Service and the MTA to conduct an immediate investigation into the Con Edison equipment failure, the cause of the outage and the response to it. The New York City subway system is the lifeblood of the city and a critical means of transportation for millions of people, which is why we are making unprecedented capital investments into modernizing the system. The MTA will continue to deploy emergency resources to address the short-term issues, and our investigation will address all aspects of today’s events to get to the bottom of what happened.”

The New York City Transit subways experienced a loss of station power at the 7th Avenue Station in Manhattan on Friday, leading to a loss of signals, escalators and communications and station lighting.
