David Silverberg, a P.E.I. doctor, is being called a hero after rescuing a man in a motorized wheelchair who tumbled onto the subway tracks in Washington, D.C.

I just kind of took a quick look to see if the train was coming. I've got a nine-year-old so I didn't want to get killed and leave her without a father. — David Silverberg

Silverberg﻿, who was at a neurologists' conference in the city, says there were only a few people on the platform waiting for the next train around 1 p.m.

A man in a wheelchair appeared to pass out and his wheelchair veered over the edge onto the tracks, said Silverberg.

"I just kind of took a quick look to see if the train was coming. I've got a nine-year-old so I didn't want to get killed and leave her without a father," said Silverberg.

"Anyhow, there was no train coming, so I just jumped down and did my best to try to pick him up, but it was pretty tough."

Silverberg said he called out to another man for help and the man came over right away.

"And between the two of us, we got him off the track. So we got him and his wheelchair out and then we just got the heck off [the tracks]."

The man was OK, except for a few cuts on his face, said Silverberg.

A Washington Metropolitan Area Transit Authority video of the incident has gone viral and several media outlets have picked up the story.

Silverberg said he just did what he had to at the time.
