Toronto Transit Commission - PowerTrunk TETRA

[HiVolt]

Few more,

100203 Run 203
100205 Run 205
100218 Run 218
100219 Run 219
100223 Run 223
100269 Run 269

100029 Line 2 Passenger PA

 

[HiVolt]

Few more confirmed Run # for Line 2. One thing that I discovered, is that the lower run numbers are used on weekends & holidays, and the ones 250 and higher are used on weekdays.

100202 Run 203
100213 Run 213
100216 Run 216
100252 Run 252
100261 Run 261
100262 Run 262

And a new one I discovered by chance today because of a crane collapse that damaged TTC overhead wires at Dundas & River,

102732 Streetcar Overhead Channel 1

 

[HiVolt]

Few more... they are trickling in slowly, as there are not many left to verify on the BD.

100207 Run 207
100209 Run 209
100214 Run 214
100215 Run 215
100276 Run 276

100297 Run 297 - This was a training run, I heard them identify as OTC (Operations Training Centre)

The other one in the database, Run 298 was probably a training run as well.

 

[HiVolt]

Getting the last of the Line 2 run numbers, this could be near the end of the list I think

100201 Run 201
100206 Run 206
100208 Run 208
100212 Run 212
100217 Run 217
100220 Run 220
100224 Run 224
100225 Run 225

100299 Run 299
I heard this run identify as a SYO (Subway Yard Operator) running a train into Greenwood Yard. So perhaps the 297-299 are used for OTC and SYO's as they see fit.

Who knows, just guessing here. These trains only show up for a short time between Warden & Victoria Park on the Birchmount tower.

 

[HiVolt]

I compared my list to the RR database, and I see one run is missing in the database, I probably just missed posting it before.

100259 Run 259.

I've been monitoring the CN Tower site for the last few days. T/G 101151 is very busy with car yard activity, lots of mentioning of track numbers etc.. There's been frequent references to "the pond" and I'm wondering of that might be the "pond" that's on the Leslie Streetcar Barn property perhaps, or maybe at the Wilson yard? I don't see confirmed T/Gs for those locations on RR just yet.

 

[ATCTech]

Woops, I see Leslie Carhouse is in the database as 101155 and Wilson as 100002. I hadn't logged either of them here and hence didn't look carefully enough online.

 

[HiVolt]

I've got so many unnamed TG's, it's gotta be at least 30+.

Sometimes its really difficult to figure out who it is or what, only get lucky sometimes when they identify themselves or the channel name.

 

[HiVolt]

I've figured out the tetra identifiers for the buses. They are not groups like the subway or the others, but rather a private connection (though not encrypted) that they can talk at the same time (duplex).

I'm not sure if this means anything for the database, because it would take forever to log them all, and I don't really plan on doing that, but at least I can provide the number scheme.

Basically its 31xxxx, where the xxxx is the bus #. I've checked this on the 3 towers I can monitor, and it appears to be the same on all of them.

 

[HiVolt]

I was also able to figure out the scheme for individual subway train cars, at least on the T1 trains on Bloor Danforth Line 2.

1215000-1215371, where the last 4 digits are the individual radio in each cab on the train.

Good work HiVolt.
Although I am not in Toronto, I am following the thread with interest.

He's come a long way. Check out post# 13 on page 1 in this thread back in February.

The student has now become the master.

Resist the dark side, he must.

 

[HiVolt]

Yeah, it's unfortunate this type of system is not easy to monitor or discover new stuff on it. It's not simulcast throughout the city, so you can miss out stuff that's beyond the towers you can monitor.

I had planned to take a ride in the subway with a laptop and see what happens down there, but with the nutjobs & junkies down there now, I dunno.

It’s been awhile since I can get reliable signal enough to decode while on the train, maybe I need to redo my entire setup. It’s mostly just the Station desk, Janitorial desk and whichever event that goes on or delay related issues.

Yeah I never tried, but I was planning to take a laptop, a USB extension for the SDR and annenna in a backpack and see what I could pick up as the train rolls along.

Be prepared every so often to readjust the actual frequency where the TETRA signal is because it moves. I can tell you all the spots on Line 2, but I haven’t taken an entire ride on Line 1 to map where it all changes.

Yeah, I remember reading that somewhere.

Bump...

So I recently installed a remote SDR (using the Airspy SPY Server) at work location which is near the Greenwood tower, and it picks it up quite beautifully. Lots of new TG's but very hard to identify.

One interesting one appears to be 102719, which appears to be the Subway Administration office, located in Gunn building at Hillcrest.

Funny they often call each other between two buildings, "Inglis to Gunn", or "Gunn to Inglis". Inglis is another building at Hillcrest. But I have heard the callsign 135/135A respond from the "Gunn side" so I assume that's the Subway Administrators. They only talk about whats happening in the subways or the SRT.

But another interesting thing I've noticed monitoring Greenwood, is that it also picks up some individual Line 2 train traffic, 1002xx.

But I also monitor the Birchmount tower at the same time from home, and what is bizarre is that sometimes the Greenwood location will pick up train comms at Victoria Park or Warden, but the Birchmount location doesn't.

Vast majority of the time the Birchmount location picks up the open air comms on Line 2 and Greenwood doesn't. Bizarre system I can't figure out the rhyme or reason, since Birchmount is much much closer to the open cut between Warden & Victoria Park.

 

[HiVolt]

Something else I've recently noticed... The Main & Current control channel frequencies are separate on Greenwood & Finch, but Birchmount & Malvern are still single, and the control channel takes up a time slot.
