The "suck it up and be grateful for what we have... ... really not a big deal at all " is more than a little incorrect. It's so wrong that it drags any merit in the rest of the post out the window. That's a line reserved for a child whining about getting a Xbox while wanting a Playstation. Or for a transit version, dealing with a Red Sox crowd. This is not a "First world problem".
Has it hit complete unusability? No. But I'm not going to run with "suck it up" and "it's really not big deal at all". It's okay to view these developments as recognize this situation does suck. I guess one can take a random ride and assess it's more pleasant than what this board would give such an impression. But that's just the imprecision of language in trying to communicate the situation rather than the issues are overhyped. No, if you ride the Red line, the slow zones is a genuine pain that makes travel times so long that it's just padding more time - time is valuable and a lot of my friends have enough means that they opting to use other modes. Things like using the GLX on a tear-down-garage weekend - I experienced it first-hand that is completely usable unless you have much free time that you can pad whole extra hours to the trip.
10 years ago, the things you hear on this board/Twitter/news/etc, you can ride the MBTA for weeks and yet not be able to run it the issue on average. Sure a dramatic fire are rare. But the slowzones and headways are measurable data and while our minds can over/under exaggerate the situation, the numbers are the numbers. The good news is it's down from the worst that was ~late March/April 2023. The bad news is it still a long way around from the service levels of the old norm, much less reaching standards that I had hope
when I made treads like this.
