The New York City subway was introduced to its youngest new passenger on Wednesday, when a woman gave birth to a baby girl in a train car.

Good Samaritans helped a 25-year-old expectant mom deliver a baby girl on board a southbound W train in Manhattan Wednesday morning, according to officials and social media videos. The little bundle of joy was born around 11:35 a.m. while the train sat in the 34th Street-Herald Square station, cops said.
