UNDATED (USA TODAY)-- A Philadelphia man is being hailed as a hero after jumping onto subway tracks to rescue a man who fell off the platform.
"I can't imagine not helping someone in that position," said Christopher Knafelc, 32, who made the daring rescue Thursday afternoon when he saw the man stumble, then fall onto the tracks, according to the Philadelphia Daily News.
Calling Knafelc a "hero," Southeastern Pennsylvania Transportation Authority Police Chief Thomas Nestel told Philly.com that at the time of the rescue, trains were coming every seven minutes. "And by the look of the platform, a train could have come at any moment," he said.
Investigators don't know what caused the 63-year-old man from Philadelphia to fall on the tracks. He was taken to a hospital and listed in stable condition.
"He didn't thank me, but I know he was thankful," Knafelc told the Daily News. "You know what I mean? In my heart, I believe he was."
The incident is the second in the past few months involving Philadelphia subway tracks. In January, a man was arrested on charges that he grabbed a woman and threw her onto the tracks at a Philadelphia subway station.
