I heard this on the TTC (Toronto's subway system) public address system: "506 Eglinton." What is this about? Any enlightened folks out there, who may have an answer?

    @DJClayworth Is travelling by subway off-topic?

    They say that all the time. "506 Eglinton, 506 Eglinton, please call control."

  • @gerrit is it always 506? In New York, they use the train's departure time as an identifier.

  • @phoog I don't remember for sure, but I'm pretty sure they do not use the train's departure time in Toronto and that it's always 506.

From the Googles:

299 Supervisor - Line Mechanics

506 is not listed, but this claims it's "janitor".

  • It seems highly unlikely that codes used in the public address system are job description codes.

Indeed, this article on Transit Toronto reveals the job code:


If you're wondering about "Eglinton", it is a subway station off Yonge St.

So when you hear 506 Eglinton, they're calling for janitors and if this user is to believed on reddit:

Laxxium • Apr 12, 2011, 6:05 AM 506 is the main janitor... 504 is the secondary Janitor if there is one on duty. 502 is the Janitor's supervisor. So if you hear 506 or 504 x 2 or x3 and then a 502, someone's in trouble for not answering their call. I know this cuz I was a summer student janitor.

The 502 code appears to be updated since this comment.

I also lived in Toronto and still visit monthly. They're calling for whoever is on duty at that station.
