A homeless woman shoved a teenager from behind onto Queens subway tracks in a random attack Monday morning, police and law enforcement sources said.

The 18-year-old victim was able to climb back onto the platform with the help of other passengers before a train arrived at the 75th Street-Elderts Lane station in Woodhaven around 10:30 a.m., according to the NYPD.  

She suffered only a cut to her leg and was treated at the scene, cops said.

Following the unprovoked attack, the suspect, identified as Shemecca Wise, 26, fled from the station on foot, police said.

She was later arrested at a nearby homeless shelter where she lives, police and sources said.

Wise was charged with reckless endangerment and assault, the NYPD said.
