The line doesn't need more than every 6 min service right now.Since the video takes place during non-rush hour times, that could be the intended off-peak frequency for the line

The digital displays at stations have been saying every 6-7 min off peak (obviously those are all test displays though). Walked the surface section Sunday and there was lots of bunching (every 2-10 min).
Every 5-6 is about as low as frequencies should get imo

No - but that's the minimum TTC service standard for rapid transit.

What were the SRT frequencies?

In 1987, peak service is 2'40" in peak (2 car trains), 4' daytime, 6' evenings and Sunday
By 1988, they moved to 4 car trains operating either 4' or 6'.
In the closing months in 2023, peak was 5' and 6'45' off peak
Line 4 operated with 7'20" with 3 trains during the pandemic till recently.

Worrying about what the frequency of the line is the least of our concerns, we should be more concerned whether the line will open this year or even before the end of this decade... At this rate they will open EG LRT and EGW LRT at the same time.

SRT did not run on street level.
For ELRT, I don't see how less than 6' is possible, even in peak. Based on dwell time in stations, traffic lights and a realistic estimate of speed between stations.
I will be happy if I am wrong.

Not to mention, as far as I’ve heard and seen, they have yet to operate the line with in-service frequencies along with the planned in-service number of vehicles. Not consistently anyways.

So this is more or less SRT frequencies which is fine for now. I've been riding the 34 for a while both from eglinton and from kennedy during mornong rush and even their frequencies aren't exactly a deal breaker. I wouldn't be too worried about 6-10min headways at this time

In the old days, almost all of our streetcar routes ran really short headways, much shorter than 6 minutes. Street running, ROW-based European tramway systems also run at short headways. There is nothing remotely undoable about it.

If you look at Ottawa, the confederation line runs 10 min off peak with the length equivalent to 3 car trains.

I think one thing people aren't considering is that observations seem only to have been made west of Laird. Are there any observations at Mount Dennis? Hasn't there been talk of operationally short-turning some (peak?) trains at Laird.
Traffic lights might be interesting - but what's the maximum traffic light cycle? I'd think you could easily run double that amount without much issue. And simply hold the occasional car at a stop, if the car ahead is too close, so it respaces. But that will be a potential issue, for the short distance where there are multiple lights.
I don't see how speed or dwell times would impact frequency. If they are all moving at the same speed, with the same dwell time, then they could move at 1-km an hour with a 5-hour dwell and still run every 3 minutes. It's all very silly of course ... but it doesn't impact frequency.

Yeah that would be pretty pathetic if trains are lined up back to back.
Somehow I highly doubt TTC lines the short turn idea. They will just mess it up and make the whole line run like a mess. When they had the line 1 short turn at Glencarin, they only did it in the morning.

Was Glencairn that bad? It seemed okay the rare morning I was up that way.
I doubt it would be any more than AM peak and PM peak anyhow.

I've heard several people mention the Laird turn back as the planned service pattern, not sure if it's true. I will say that the TTC takes a long time to turn back vehicles, often delaying the one behind
