Stadium is now the start of my morning commute, so for the last month I've been up there catching the 5:23 train southbound. I was pleasantly surprised (and a little flustered, because the thing was a couple minutes earlier than expected, too) to see the train pull into the West track (the proper Southbound track) as opposed to the East track where trains had been single-tracking.
It was kinda wild to step into the train, cross over to the other door (which stayed closed) and see another platform. The new platform isn't done yet; a lot of the precast platforms are in place, but there are still gaps, no access ramps, and no caulking in the joints yet, I think we have a bit of a wait still for that to open. But the train is slowly taking shape! The roof forms are starting to be clad, and the public access ramps on the north end of the station are mostly in place.
