Toronto Transit Control Live Audio Feed on Broadcastify.com
If you ever want more info about a transit delay than what you get from official communications, or if you want a better sense of daily issues on trains and buses (most of which are never reported to the police/press), check out this unofficial feed: https://www.broadcastify.com/listen/feed/31629
This broadcast is not official. Here's a RadioReference forum post with the technical details re: how someone can monitor the TETRA system that TTC uses to communicate across its network. This broadcastify feed is picking up the signal from the Birchmount location/frequency.
I used last time I was on subway and the trains stopped, a man jumped on the rails and went into the tunnel, the where searching for him for 10-20 minutes!
