A madman disguised as a construction worker turned a Brooklyn subway car into a bloodbath during the early-morning rush Tuesday, setting off smoke bombs before opening fire and wounding 29, officials said.

The shooter — who has yet to be apprehended — was wearing a neon orange and green construction vest and a neon green helmet and muttering to himself on a Manhattan-bound N train when he unleashed bloody havoc just before 8:30 a.m.

The gunman suddenly put on a gas mask and released two smoke grenades as the car pulled into the 36th Street station in Sunset Park, cops said.

“Oops, my bad,” the suspect mumbled, according to witness Fitim Gjeloshi, after opening the canister and then pulling out an ax and dropping it to the floor.

As the crowded subway car filled with smoke, the shooter took out a 9mm semiautomatic Glock and fired 33 rounds at commuters, hitting 10 victims and leaving at least 19 others wounded. Those hurt included two teens ages 15 and 19, a pregnant woman who was shot in the leg, seven men and three women, law-enforcement sources said.

Of the ten victims hit by gunfire, five were listed in critical but stable condition, while others suffered from smoke inhalation and other related injuries.

Police later identified Frank James, 62, as a “person of interest” in the shooting but have not yet determined if he was the triggerman.

James had previously railed against Mayor Eric Adams and made bizarre threatening rants on YouTube.

He said he’d been treated for mental-health issues at a facility with “violence,’’ not “physical but the kind of violence a child experiences in grade school … that would make him go get a gun and shooting motherf–kers.”

A straphanger named Claire who witnessed the shooting said of the gunman, “I thought he was an MTA worker at first,” adding so many rounds were fired, she “lost count.”

The gun used by the shooter, who had three extended magazines on him, jammed in the midst of the bloodshed. One of the magazines was found in a backpack, the other on a seat and the third in the weapon.

The gun’s malfunction was a fluke that law-enforcement sources likened to a miracle.

“It was lucky that it jammed because we could be talking about a lot more people in hospitals or worse,’’ a law-enforcement source said.
