Hero rescues baby in stroller from subway train tracks

He's faster than a speeding train.

A heroic straphanger saved a nine-month-old boy Tuesday after a gust of wind blew the baby's stroller into the path of an oncoming subway train in New York, authorities and witnesses said.

The boy took the terrifying tumble about 12:40pm atop the elevated Van Siclen Avenue station on Fulton Street in Cypress Hills, Brooklyn.

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, the brave Good Samaritan selflessly jumped in after the youngster and scooped him up as a train fast approached, Ansari said.
