Trapped by a 'pain in the butt' train? Here's how to complain:

It's the first thought that crosses DaynaCurtis' mind when asked to describethe Canadian Pacific Railway tracks at Adelaide Street near Central Avenue.

"This is the worst railway crossing in London," she said. "It will stop dead, like the engine will stop dead right in the middle of the intersectionand then do whatever, hookup, backup, it's just annoying."

And it's not just people like Curtis who drive.

Louise Blakeyhas her own way to describe the crossing.

"It's a pain in the butt," she said. "Lots of times it makes me miss buses."

A few choice words

It seems anyone you ask hasa few choice words about being trapped by a train, forced to wait asit rumbles past them.

And while we love to tell war stories of just how bad it was, it seems we only tell those stories to each other.

The country's railroad regulator, Transport Canada, saysithasn't had a single report of a stopped train on CP tracks in the last six months.

This is despite Tuesday's incident that saw a train straddle Adelaide for close to an hour and saw Londoners vent their frustrationson social media.

'It's a lot easier to tweet it out'

So why is that?

"I think because it's a lot easier to tweet it out," said Megan Shore, a professor who studies social justice and activism at King's University College.

"The more this happens, the more upset people are going to get," said Shore, noting that most people probably don't know there's an official channel where people can launch their complaints.

"Now it's time to do something about it," she said. "But that takes effort. That's the difference."

Despite all the complaints Londoners made on social media during Tuesday's hour-long traffic jam at the tracks, Transport Canada says it didn't get any complaints from London.

Feds launch investigation

While plenty of people reported waiting for up to an hour on social media, aspokesperson for the rail company would only saythe train on Tuesday stopped at 6:45 a.m. because of a mechanical problem andrefused to say for how long.

Federal regulations state that stopped trains can't block crossings for more than five minutes, and that they have to move immediately if emergency vehicles need to pass.

Transport Canadasaid it will now be investigating Tuesday's incident after receiving a call from CBC News.

"The department will not hesitate to take appropriate action should any incidents of non-compliance with theGrade Crossing Regulationsbe identified," spokespersonAnnie Joanettewrote in an email.
