Circling back around to this, today's presentation on RL/OL weekend work says they did (among other things) last weekend:So lurking around, I found this guy who seem to did some back-of-the-napkin math.
If this guy is right, we'll need 5-6 years of weekend downtown shutdowns. Is this what we're looking at? Shutting down whole weekends in the Downtown core to replace ~300'-~500' feet of track against 58,000' of track for the Orange Line alone?
If this guy is right, then the start of the weekend Downtown shutdowns was not a "ripe-the-banndaid" moment to finally start to bring service back to someone respectable. It's the start of a new even lower-service normal. And that amount of track they're replacing, is 300'-500' a number indicating a make-the-most-of-it-round-the-clock replacement work? Or more indicative of a cost-cutting measure of track replacement that could be achieved overnight? Or is it neither, like it is round-the-clock, but incredibly slow (or is actually even fast)?
I don't know, but that's why I post here. Is this what we're looking at?
OL: Replaced 520 linear feet of track + Installed 2,682 linear feet of Continuous Welded Rail strings (I'm unsure why they split up the numbers like this)
RL: Replaced 2,400 linear feet of track between Harvard and Porter Square
So it seems it is possible to do much more work in a weekend than we've seen out of previous weekends of work. Didn't have time to watch to see if any explanation was provided regarding the drastically increased productivity, but it looks ike some of the productivity assumptions from the initial weekends may not be accurate.
