Metrolinx is investigating after a video was posted of a man riding on top of a moving GO Train.

“I don’t know what this person was thinking but nothing can justify this,” Metrolinx spokesperson Nitish Bissonauth tweeted Monday. “@GOtransit Safety Officers are investigating and take this very seriously. Don’t be like this guy, don’t ever try this.”

The 10-second clip, first posted to the Instagram account 6ixbuzztv, shows someone sitting, then standing on top of a speeding GO Train. It’s unclear exactly where and when the video was recorded.

The transit company was first alerted to the video Saturday, and opened the investigation shortly thereafter, Metrolinx spokesperson Anne Marie Aikins said. She said she believes the company already has some leads on a suspect.

Aikins said she felt “nauseous” when she first saw the video, and wondered if the man who posted it was still alive.

“And then I got angry,” she said. “It’s such an unnecessary risk to your life. And an unnecessary waste of our resources.”

Aikins cautioned potential imitators that hitching a ride on top of a GO Train could lead to serious injury or death.

“You may think it’s worth your time getting all those views . . . and people liking it and that sort of thing may seem like a thrill, but it really won’t be,” she said.

“The last thing we want to do is to have to go to someone’s loved ones to tell them someone in their life is gone.”
