A 15-year-old boy train surfing atop the Staten Island Railway on Wednesday afternoon struck his head and died performing the dangerous stunt near the Eltingville stop, authorities said.

“This was an awful situation that demonstrates again the deadly risk taken by anyone who attempts to subway surf,” said NYC Transit President Richard Davey. “Our hearts go out to loved ones who have senselessly lost a child and we continue to encourage teenagers find safer ways to seek thrills.”

The boy was found around 1:15 p.m. unconscious and unresponsive with a head wound on top of the train, according to authorities and the Staten Island Advance.

The youth was taken to Staten Island University Hospital North, where he died.

Authorities received a report of a passenger who had fallen between cars of an SIR train between Annadale and Eltingville.

The boy was riding inside the train car when he decided to climb on top and hit his head on an overhead structure, according to the MTA.

The investigation is ongoing.

Authorities have been urging youths to shun subway surfing after a an alarming spike in incidents last year.
