"We had a male who fell onto the tracks and sustained a head injury," said Deputy Cliff Yates of the Los Angeles County Sheriff's Department.
The train came within inches of running over the victim. In an amateur video taken by an eye witness, the man was seen still lying on the tracks with the subway train right next to him. Paramedics were working to get him out.
Tony Saucedo, a witness, took the pictures with his camera. He said people in the station originally thought the man was dead.
"I'm pretty sure that's why they brought out the sheets, so they could cover up the dead body so that nobody would see him. I'm pretty sure that's why they took the sheets away because they realized he was alive, because he started screaming from the fact that they were moving him from beneath the train," said Saucedo.
The incident stopped the Red Line service for around 20 minutes. The man was taken to the hospital, but he is expected to be okay.
People who witnessed it all said he is lucky to be alive.
"You don't get that every day from a guy underneath a train. Once you see that, it's life-changing. So there's a God out there and I believe a miracle did happen last night," said Saucedo.
No one else was hurt in the incident. Investigators are looking at surveillance video to figure out what exactly happened in the few minutes before the man ended up on the subway tracks.
