Progress from today at the crossing beside Vi's for Pies. Track is in and lots of hoarding is either up or is being setup. Pretty sure asphalt/road is in and they're just doing median/track concrete work now.

Well that's interesting. They're doing embedded track with the rail in place when they pour the concrete, as opposed to the method used on the VLSE where they poured the concrete, left a trough, and then installed the rail in the trough, securing it in place with an elastomeric grout. That explains the earlier image of the short section of complete track with the rail and flangeway fillers hanging out of it.

I remember reading in one of the transforming Edmonton posts that casting rail in the bed allows for more control and precise track placement, so this seems to be a good thing

My non-professional opinion is the same. You have the rails gauged before the concrete is even poured. I strongly believe that TransEd had to bring in that milling machine because the rail wasn't quite properly gauged at locations on the SE line.

This was track laying near Grey Nuns. While there are spacers attached to each side of the rails, but there's nothing actually gauging the rails. While in theory that rig should hold everything in place perfectly so that rails are in gauge, it just seems to me there's more room for error.

Traffic along 87 Avenue will shift to the other side.
