A 49-year-old subway driver was punched in the face while working in the Bronx, police said.

Colleen Perkins, who is believed to have about 15 years of experience with the MTA, was the conductor of the northbound 2 train around 6:05 p.m. Friday when an unknown woman punched her in the face near 149th Street and Third Avenue , the cops said.

Perkins was taken to Lincoln Hospital where she was in stable condition, the NYPD said.

Perkins was unreachable Saturday afternoon, but a neighbor in her Bronx apartment building who said she was also an MTA bandleader and knew all too well the dangers lurking in the system.

“It’s definitely dangerous,” said the woman, who said she was assaulted at work as well, and asked that her name not be used.

“It’s definitely not safe. It’s a scary experience to work in the subway. As a bandleader with a bunch of mentally ill and drug addicts around you… they’re unpredictable,” the woman said.

She continued: “Someone threw an unopened bottle of Comet at me. It banged on my window so hard I thought it was going to smash the glass. Thank god it didn’t hit me. I closed my window just in time.Sometimes their body language or cursing at you will let me know to close the window.
