This photo looked better when I took it. It's a crappy shot looking southeast from the southbound lanes of Black Creek Drive at the Eglinton intersection. The construction is the Black Creek flyover from Mount Dennis Station to the west to the western portal east of this intersection.

They've banded around crush-loading values for a TTC Flexity of 200. But even if you use the peak design load of 130 (which seems quite reasonable to me, it's 108 for an ALRV and 74 on a CLRV) ... which is 390 for a 3-car train.
If you run every 2 minutes that's 11,700. 15,000 might be pushing it ... which would be about one every 1.5 minutes. But it should be more than 9,000.
Especially as the Eglinton Line 5 cars are a bit wider than the TTC Flexity.

In the underground section, sure, you might get every 2 minutes, but not on the surface section.

It's easier to run tighter frequencies (in the tunnel portion) with shorter trains as use of the cross-over tracks is that much shorter. 90 second frequencies should be quite a bit easier on Eglinton than it will be on line 1/2. Dwell time at interchange stations will be the main capacity constraint and the plans for those stations look pretty good for the Eglinton line portion (centred, plenty of space, etc.).
Of course, even just 10k from East + 10k from West unloading at Yonge to transfer will very rapidly overload Yonge with passenger lines reaching all the way to the arriving Eglinton trains.

the smaller trains means that dwell times will be smaller too. Less people to get on and off.
Also, 10k will never be needed on the surface portion. demand will be too low forever more or less, and if it does exceed that, as rbt mentioned, there will be much larger issues elsewhere on the network.

To alleviate the crush at Eglinton, is the TTC able to add another car to the line 1 trains?

Nope. The current trains are a one-size solution. I suppose they could switch to the older model but I also don't know if all stations could support the extra car.

After ATC is installed its possible.

Albeit it wouldn't be a regular sized 60 foot car, it would be closer to half of the size.

Yeah my first thought was, how is the additional car going to fit the platform?
Also, I don't get how capacity increase in Line 1 would necessarily alleviate the crush at Eglinton.

Gosh, if they ever need that much capacity on the piece of Line 5 in Scarborough, the problems near Yonge - and at the Yonge transfer. And on the Yonge line south of Eglinton would be immense!
I'd think by then, we'd be in the latter half of the century, and the answer would be lines on Lawrence and/or St. Clair.
Gosh, can you imagine a St. Clair line, that goes from Warden Station to St. Clair station? Now that would provide some connections that you can't do in a car!
In theory they could add an additional car. Though probably not worth it (would it have to be powered?), and more likely it would only come on future trains.
TTC hasn't purchased any cars that small since the 1950s! And those were 56-feet, not 60.
All the current ones are closer to 76-feet.
A 7th car would be about 45-feet - which is closer to 4/5 of those old card - not 1/2. Though presumably you could extend a bit into the tunnel on each side, as the doors are not at the very end of the cars. So I don't know if they need be that much shorter.
More likely though that just go for seven 72-foot cars, or eight 63-feet cars.
Montreal has the same length platforms, and they use it all with nine 56-foot cars - about the same lengths as the original TTC subway cars.

What changes with ATC? Even in the best case scenario it adds to Yonge the equivalent of about 10% of Eglinton's capacity; and I'm not expecting anywhere close to best case (Bloor dwell, King dwell, Finch turn-back time are not resolved by ATC).
