A man committed suicide at the Times Square station Wednesday by doing a “swan dive” into an oncoming train, witnesses told The Post.

The man was hit by a northbound N train as it pulled into the station around 9:20 a.m., according to an MTA spokeswoman.

He was pronounced dead at the scene.

“He just jumped,” said an MTA worker who said he witnessed the suicide. “He did like a swan dive.”

“Part of his head came off,” the worker continued, gesturing to the area above his eyebrows.

The incident comes two days after 49-year-old Connie Watton was shoved to her death in front of a No. 1 train at the same station.

Melanie Liverpool, 30, was charged Tuesday with second-degree murder in connection with the fatal push.
