A Long Island teenager celebrating his 18th birthday was killed after being hit by a train on the Upper West Side while crossing the tracks with friends. Witnesses described the horrific scene to the New York Daily News:

"He got smacked by a 2 express train," said Bronx resident Anthony Escobar, 36. "He got fried and mangled."

"I heard the conductor yell, like give out a scream or a moan," said John D'Alessandro, who was in the first car of the train.

The subway came to a screeching halt and lost its power. Panicked passengers waited anxiously in the dark for more than an hour, as cops and firefighters tried to salvage the victim's body.

"I saw the arms, blood on the hands," said Leola Browder, 28. "Some people were upset and scared. Others were more worried about going where they had to go."

According to NBC New York, the teens were returning to Penn Station when they realized that they were on the wrong platform, hence their decision to cross the tracks. Rather than access the platform from the other side, they tried to run across the tracks and the teen was struck by an oncoming train.
