I seem to recall the first Broadway substation was going to be pretty close to the station at Great Northern Way, possibly where the emergency exit comes out. So that doesn't map up with whatever they're doing at Fraser Street.

There should be a substation around Broadway-City Hall too, if I recall correctly, but I can't find the document I'm looking for to confirm that.

Not sure if it changed but I found another reference in a project document.

Propulsion Power Substations
Table 1.2.3-a sets out the mnemonics for PPSs for the Broadway Subway Project.

I assume the VCC-Clark upgrade is outside of the scope of the project so that's why it's not mentioned.

Also confirming that there are only 2 substations/power feed points, with the other being located at Arbutus?

I haven't been able to find it confirmed in any of the documents that I have.

Is that a piece of track with fasteners sitting on the concrete pad on the right side of your photo?

This could be for testing/training/trialing rail installation on both flat and superelevated sections.

And the section on the left is sloped which seems weird. It seems like those sections have been placed there since Spring.

Back in July it seems like they were setting up some kind of of scaffolding for a concrete form hanging off the side of the guideway above where these "foundations" are placed. There's also a gap in those supports above that section.

And back in April it seems like the supports were setup but removed later to do the additional concrete work.

I don't think that is related, the section the protrudes out should be for a switch machine like here:
