A crazed and naked man who was ranting about Vietnam jumped onto the train tracks in a Brooklyn A/C station and and touched the electrified third rail on Wednesday morning, say witnesses.

The man appeared to be on drugs as he rattled off military terminology and talked about plans to kill himself.

“He was talking like he in the army. ‘2-4, got you, there’s a bomb coming… 2-4 partner, I’m gonna die for you, I love you,” said Doris Williams, who was standing on the platform.

The incident happened at 11:36 am on Wednesday.

Williams and her husband tried for several minutes to convince the man not to kill himself. He jumped onto the tracks and touched the third rail as they turned away to call 911.

“He went out on the tracks and touched the third rail and died,” said 42-year-old Rocky Williams, who was waiting in the Franklin Avenue station when the apparent suicide happened.

Emergency personnel found the man dead in the tracks. They are investigating the incident and do not suspect any foul play.
