I thought this video was going to be poorly written but found it to be a rather good overview on the state of the TTC and it's future.

That's a way to pay more and what happens if the others don't come on board re funding? Running two models on same line adds to cost. It's 'all or nothing'.

If running two models on one line causes problems, that is symptomatic of a much larger problem in the city. Standardization should be a 'nice to have' that we can possibly strive for, but it should not inform fleet policy when there are other considerations at play.
All or nothing is also a very bad approach if you have two lines in the pipeline which may one day possibly be completed and will require extra trains to run. If the feds don't cough up, then what do? Tell the people of Scarborough and York Region that there's not gonna be a subway for them after all? Well, we should have done that already, but it's a bit too late to close Pandora's box now.

I guess adding new TR's trains to line 1 was a problem as they had to run 2 different sets for a number of years until there was enough TR's to move the T1 to line 2? So what is the different between Line 1 and 2 stopping doing it on line 2??
TTC ran how many different H series cars on the subway network for years long before the T1`'s show up??
You can find system that run different sets of trains on the same line and they seem to have no issues doing so.

I'm sure there is going to be a federal announcement for the funding at the right time for them to do so.
They need the votes.

The provincial government needs to complete the paperwork to request funding first. This took them years for the last round of transit funding.

TTC have already announced that Greenwood will be modified to handle the T1 replacement trains. It's part of the $2.8 billion budget for Line 2 Capacity Enhancement (which is in addition to the $800 million for ATC, $2.5 billion for the new trains, and $1.5 billion for the Bloor-Yonge station enhancements). The Capacity Enhancement program runs until 2041, and the cost in the 10-year budget (2023 to 2032) is $1.1 billion, of which about $0.9 billion is funded.
Presumably the Greenwood yard upgrades are within the next 10 years, but it's not clear to me what in the next 10 years is unfunded. It looks like the initial focus is on Spadina station, including the extended streetcar platform, but the latest update says the design for the Greenwood modifications are underway.
So they could be identical!

Curiouser and curiouser.
There's no way they'd be getting non-open walkway trains these days. This will be an interesting design, assuming someone doesn't come to their senses.

Just because they are configured as two-car couplets doesn't mean that they will be stored in that manner.
Electronically, the TRs are configured as 3-car sets with 2 sets making up a train. But they certainly aren't stored in that manner, and the vast, vast majority of work done to them doesn't require those pairs of sets to be broken apart.
My understanding about the changes to the maintenance facilities at Greenwood is that they will echo the changes done to Wilson, where improvements were done in a staged basis to allow the existing facilities to operate while some of the new facilities will be built. And the new facilities will be designed to allow an entire 6-car train to be maintained as a whole, without taking it apart.

I thought that the plan was to allow the cars to be separated and moved in the yard using remote control or some console with a dongle? (For the cars without a cab)

That has never been a plan that has been conveyed to me.
And honestly, it makes no sense as the couplers are a major maintenance expense that they would like to do without if they can. More coupling and uncoupling means more wear-and-tear, which means more maintenance.

The trains are to be supplied as six-car sets of three married pairs as shown in the drawing below. This differs from the TR trains on Lines 1 and 4 which are explicitly configured as 6- and 4-car units respectively.
The A cars are cab cars with full controls. The B and C cars are intermediates. All B and C cars will have hostler controls at one end for manual operation as independent sets. This is a different configuration from the TRs which only operate as full trainsets.
The cab-end truck of the A cars will not be powered. This is to avoid ATC position measurement problems caused by wheel slip/spin. A full 6-car train will have 10 powered trucks.
The only difference in the specification between a “B” car and a “C” car is that the combination “A-B” (including a cab car) or “B-C” (without a cab car) is possible, but not an “A-C” pair.
From Steven Monroe's blog.
The main difference would be that the lead cars are going to be trailers or non powered cabs. Not sure how that makes them less prone to wheel slip.
