A SHOCKING video has surfaced online of two women fighting on a crowded New York train - as a baby stroller belonging to one of them rolls out the door onto the platform.

In the video, the woman pushing the stroller gets into an argument - presumably over a seat - as the L train pulls into a station, the New York Post said today.

During the confrontation, which quickly becomes physical, the baby’s stroller rolls onto the subway platform.

As the fight continues, horrified commuters attempt to break up the fight as well as bring the baby’s disappearance to the woman’s attention.

After the fight is broken up, the woman with the child walks off the train and pushes the stroller, baby in tow, along the platform as the other woman continues to shout from the subway car.
