An intoxicated suicidal man hopped onto the subway tracks in Manhattan and tried to touch the deadly third rail, snarling train service on several lines during the Thursday morning rush, MTA officials and police said.

The man jumped onto the express tracks on the 2 and 3 lines at the 14th Street-7th Avenue station at about 8 a.m. and bolted into the tunnel between 14th Street and Christopher Street, according to officials.

The MTA immediately cut power to all tracks between 34th Street-Penn Station and Christopher Street and the man was spotted attempting to touch the third rail and was seen running along the tracks.

The NYPD responded to the scene and took the man, whose identity was not immediately known, into custody, removing him from the tracks at about 8:35 a.m., cops said.

The man, who police say was intoxicated, was taken to Bellevue Hospital for a psychiatric evaluation.

Twitter video taken by a straphanger aboard a stalled train in the dark tunnel shows the man walking along the tracks.

“Man walking towards @MTA 2/3 subway – our train slammed on breaks to avoid hitting him #nycsubway #MTA,” Twitter user @kcavery captioned the brief clip.

Due to the incident, southbound 1, 2, and 3 trains temporarily terminated at 34th Street-Penn Station.

No. 2 trains ran on the 5 line between Nevins Street and 149th Street-Grand Concourse in both directions and the 1, 2, 3, 4 and 5 trains were hit with delays.

Power was restored and service resumed on the affected lines at 8:39 a.m., the MTA said.

“We apologize for any inconvenience,” the MTA said in a statement.
