A woman you don't want to mess with

That's Lisa Burt-Jones from CN Police.

The ticket she's about to write could cost you up to $5,000.

You might even do some jail time.

Unless you want to mess with Lisa and her ticket-book you'll want to keep off her bridge.

CN Police and City Police are down at the Algoma Central bridge to the U.S. today for what they're calling an "education and enforcement" Safe Community blitz about the dangers of trespassing on railway property.

They want you to know that they're cracking down on anyone fishing or swimming from the bridge or walking on it.

Railways can be very dangerous places, Burt-Jones says.

Just yesterday, she was at the Algoma Central yard near Hudson Street, and she saw someone trying outrun a train.

The train was backing up and the individual was running to cross the tracks behind it.

"He was so close. If he'd stumbled he would have hit his head or been hit by the train," Burt-Jones said.

Stuff we learned today:

- you can be charged with trespassing on a railway bridge even if there's no sign

- the ACR bridge across the St. Mary's River is wired to the hilt with sensors and cameras

- they have loudspeakers on the bridge that can be used to yell at you to turn back
