Bertlett Garage is still falling down. on Washington Street near Dudley. They have no money to rebuild but they could level what's left of the buildings there and put strictly just buses there. Change some buses that could be closer to this station depart from here and rework it to fit others are Charlestown, Lynn or others.

Barlett's been closed for 9 years. If the property hasn't been outright sold by now, it's the BRA that's holding it up because the T wanted that parcel off the books ASAP.
What they want to do is super-pool the fleets at more of the big garages, and rein in the outer ones for more of a service-hours storage/layover purpose instead of as permanent base. Which makes a lot of sense for labor and maintenance consolidation, and also makes the fleet assignments a lot more fluid. Right now you have maint staff permanently assigned to every outpost...including tiny ones like Fellsway and Lynn. Which means they can only assign certain types of buses out there to match the parts and mechanics onsite, and don't move 'em around very much.
The big shift the recent yard study identified was building a big facility at Wellington that would super-pool with Charlestown and Everett Shops. Existing Orange Line home base with lots of land (can trade horizontal for vertical parking if they want to cannibalize part of the lots), universal highway access, and they can shuffle staff from Everett and Charlestown--which are pretty much in direct eyesight--almost as if it were one office campus. If they did that Fellsway would close entirely, and Lynn would get demoted to day storage staffed by field inspectors.
They're also looking at a little further consolidation near Southampton/Widett Circle for more of that "office campus" labor efficiency, and building another biggie at Riverside for the Pike/128 access and to bootstrap onto the Green Line home base (although Newton and area businesses hate the idea because it starts crowding out the TOD). I think they ought to use part of the unused wasteland at Readville for the same purpose, but they've doubled down on that new eyesore of a Forest Hills facility instead.
But figure they do get their efficiencies and fluidity at these super-nodes. Then they
can open more straight-up layover yards on the outskirts that are only remote-staffed, only utilized during main weekday service hours, and don't have to have any permanent infrastructure besides one fueling pad, an inspector hut, and maybe a toolshed with portable lift for emergencies. Dot a few of those remote installations at Braintree, Anderson-Woburn, Waltham, wherever. It's a lot more flexible to do that + a couple "office campus" super-nodes than to have to have every single garage weighed down by the same overhead.
