A crazed man caused a stir when he went running along the subway tracks in the Upper West Side on Sunday morning, authorities said.

Cops chased the crazed man after he ditched his coat at the 96th Street station and began walking along the 1,2 and 3-line tracks heading downtown.

First responders arrived to the station at West 96th Street and Broadway around 8 a.m. after receiving several calls about an emotionally disturbed person on the train tracks, a person laying on the tracks and a man trying to jump onto a train from the tracks.

But Upper West Sider Stefan Loble, 44, who was in the station at the time, described an even more bizarre scene.

“There was a guy in a white t-shirt carrying a vinyl record,” he said.

“A big 12-inch vinyl record out of [its] sleeve.”

Loble had just boarded the downtown 1 train with his two kids, but his subway barely made it out of the station.

“They close the door, they go 20 feet — there’s the guy,” he recalled, adding that the man was on the uptown tracks when he crossed over to the southbound line.

Before his train was evacuated, he saw the man on the tracks “and then he disappeared. They couldn’t find him. No one could see him.”

Subway travel was halted and the power to the tracks was cut while police followed the man into the tunnel and out to West 86th Street and Broadway, where he was apprehended about an hour later, authorities said.

EMS transported the unhinged goon to Mount Sinai St. Luke’s hospital for evaluation.
