A 25-year-old woman from Florida gave birth on a W train in Midtown Manhattan on Wednesday morning. She had been missing since last summer, her sister said.

The rider revealed new details about the episode, including a request from the mother to cut the umbilical cord with a pocket knife.

A packed train in Manhattan quickly turned into a delivery room and straphangers became midwives, as riders banded together to deliver a baby when the mother went into labor while aboard the subway. The 25-year-old went into labor while she was aboard an uptown W train at the 34th Street Herald Square stop around 11:30 a.
