Nice wealth of info!
But the MBTA, like someone else said, should've replace the old decrepit trains about 10 years ago! Why do they wait so long to replace old dilapidated equipment that that has been inconveniencing commuters for about 10 to 15 years before getting new stuff!!
This, I just can't see & is beyond me!!
The MBTA racked up a bunch of debt in the 90s and 2000s through far flung commuter rail expansions and the silver line, and MassDOT wasn't helping because they were busy with the big dig. When the recession rolled around, mbta revenues fell (they rely on the sales tax) and the state didn't do enough to pick it up. As a result during the recession and just after there was lots of deferred maintenance.
Well that, and MBTA pensions are more lucrative than any other state agency. But I won't get into out of control costs (green line extension).
