He’s faster than a speeding train.
A heroic straphanger saved a 9-month-old boy today after a gust of wind blew the tot’s stroller into the path of an oncoming subway in Brooklyn, authorities and witnesses said.
The boy took the terrifying tumble around 12:40 p.m. atop the elevated Van Siclen Avenue station on Fulton Street in Cypress Hills.
His mother had apparently forgotten to put the brakes on the stroller as she was tending to his three siblings, according to Khalima Ansari, 21, who watched the drama unfold and called 911.
A burst of breeze set the stroller in motion, and down the child went into the rail bed of the J-line.
Without missing a beat, brave good Samaritan Delroy Simmonds selflessly jumped in after the youngster and scooped him up as a train fast approached, Ansari said.
“He’s a hero, no doubt about it. He saw the train coming,” she said, noting that the stroller landed with the kid still inside.
“Anybody could have thought, ‘Well I don’t want to lose my life,’ but he didn’t care. He just jumped down and he got the baby just in time. I respect him a lot for that,” said Ansari, a college student from Brownsville.
Ansari said Simmonds picked up the tot and the stroller and put them back on the platform, with some help from the child’s shocked mother and another good Samaritan.
“And then he pushed himself back onto the platform. But the train was seconds away. The driver was honking the horn and then stopped seconds before it got to them,” she said.
The train squealed to a halt a few feet from where the kid and his rescuer Simmonds had been.
As a result of slamming into the wood planks and steel rails, he suffered a “big gash in the middle of his head so you could see his skull,” said Ansari. “And it was gushing blood.”
Ansari told the upset mom to keep the baby awake as his eyes started to blink slower and slower.
“She was so shocked, very scared. She kept patting the baby on the head where the gash was with the blanket, trying to stop the blood,” Ansari said.
The plucky kid didn’t start crying until EMTs started cleaning the wound with solution, she added.
The wounded baby was rushed to Brookdale Hospital and is expected to survive, authorities said.
Simmonds was uninjured and left after discussing the incident with responding police.
“He just looked shocked and scared and nervous all at once,” said Ansari.
“He didn’t even think about it. He just jumped down there and got the baby just in time.”
