Two subway trains became stuck in the Harlem River tube on Sunday night when a power outage caused the disruption of several lines — leaving hundreds of passengers to be evacuated, sources said.

A southbound 2 Train and northbound 3 Train were traveling through the tunnel at around 10:40 p.m. when a transit power outage at Rail Control Center disrupted service, according to law enforcement sources.

A total of 150 people were evacuated from the southbound 2 Train and 250 were evacuated from the northbound 2 Train, the sources said.

The MTA said “a power surge disrupted the connection between the Rail Control Center and our signaling systems.”

“I have directed the MTA to do everything possible to mitigate the impact of tonight’s service disruptions,” Governor Kathy Hochul said in a statement.

“MTA personnel are assisting customers and NYPD is in the system supporting these efforts. We are in talks with ConEd to determine root cause & rectify as soon as possible.”
