Rail is rail. The vehicle itself doesn't care.
The issue to some extent is trying to get the (actually very heavy) trains running incredibly frequently under CBTC to hit the 20,000+ ppdph capacity target. The system needs to hit capacities that are a real stretch for it's vehicles and infraRail is rail. The vehicle itself doesn't care.
(There are arguments to be made about things like rail cant, wheel profile, etc,. but by and large in this kind of implementation, you're not going to find huge variations or differences between them. We're not talking about the difference between the TTC's subways and streetcars here.)
But that said, the line was certainly built to seemingly a far higher capacity than the vehicles seem to indicate. I suspect that any comments about the vehicles running on "heavy rail tracks" have been misunderstood, and have more to do with the construction of the system as a whole.

It's amazing (-ly stupid) that they didn't take this opportunity to double track the Trillium Line. I get that the Dow's Lake Tunnel isn't twinable, but other chokepoints like the Walkley St Bridge (which is being extensively rehab-ed) and the Ellwood Diamond (entirely new bridge) should have been double tracked from the start.
Agreed. Or at the very least: future proof with piers and abutments to support the installation of a future rail decks.It's amazing (-ly stupid) that they didn't take this opportunity to double track the Trillium Line.

Sure it's twinable!, stuff like that has definetly be done, its not that large of a tunnel as well. I am sure the Swiss do it pretty regularly . . . just look at this . . .It's amazing (-ly stupid) that they didn't take this opportunity to double track the Trillium Line.
