A 45-year-old architect was killed on the New York City subway Wednesday night while apparently trying to "surf" the train, according to local media reports.

Witnesses say Bronx resident Isabel Rios was riding the 6 train on an elevated track when he moved into the space between cars and climbed on top, DNAInfo New York said.

While "surfing" the train, his head struck an object, possibly a support beam.

Rios was found unconscious and unresponsive on top of the train, and pronounced dead at the scene, The Wall Street Journal said.

The New York Daily News reports that Rios had been involved in rebuilding parts of Staten Island damaged by Superstorm Sandy in 2012, and that he was engaged to be married.

He was a really troubled artist. He was very gifted and very talented. I admired his talent and his work,” Carol Parkman, the mother of Rios' fiancee, told the Journal.

"Subway surfing is simply one of the dumbest things you can do," MTA spokesman Kevin Ortiz told DNAInfo. "Don't do it."
