A 16-year-old girl was seriously injured when she struck a beam while subway surfing atop a Queens subway train Wednesday, cops said.
The teen was struck as she rode the top of a Far Rockaway-bound A train pulling into the Broad Channel station near West and Noel Roads in Broad Channel around 3:12 p.m., according to law enforcement.
The blow caused the girl to fall onto the top of the train, said police.
Medics found the teen on the train and rushed her to Brookdale University Hospital. She suffered serious injuries, but is expected to survive, officials said.
According to preliminary reports, a young man was on top of the train with teen, but jumped off and ran away before first responders arrived, sources with knowledge of the case said.
Eric Eiler, 56, told the Daily News he was riding the train on his way home from work to the Rockaways when other riders started “screaming” that someone had clambered atop the cars a few stops before Broad Channel.
It was after he exited the train at Broad Channel that Eiler looked up to see the girl dressed in black writhing atop the train, he said.
“She was lying there, rolling around, but still conscious,” said Eiler. “Thankfully, she survived. You hear about all these incidents. People are dying and people are still doing it.”

Wednesday’s injury follows the death of a 14-year-old boy killed when he fell from a train as it rumbled over the Williamsburg Bridge on May 22.
Akhi Butler was found dead beside another injured teen, 18, on the roadbed of the J and M lines on the bridge about 6:50 p.m., sources said.
The victim’s family begged other teens to lay off the dangerous stunt in the wake of their loved one’s tragic death.
“Just stop! Stop!” relative Sharean Butler said. “Social media clout isn’t worth your life.”
“You can get that somehow, someway, another way that’s more safer,” she added. “That is not it at all. And most of the times it ends up tragically.”
