Seeing 4-car sets of these run on the Riverside/Fairmount/Rt128 Urban Rail every 15m would be an absolute transit wet dream..
They're even purple .

F-Line, any chance the Green Type 10s could be autonomous? Although that's difficult with the at grade crossings.
I suspect it's unions that made that happen. I'm also amazed that a complete signal redesign project and brand new rolling stock isn't making self driving a priority, something London has had since the 90s on the DLR. My completely misguided hope is that the new signal system will be good enough to support near self driving trains with minor modifications but I know that's far too optimistic.We've had self-driving trains in the US since the late 60's, but I can't think of any in the world that aren't 100% grade separated.
The modern signal project on red blue, and orange should have led to self-driving, but alas, they did not.
I prefer the Elizabeth line in that case, but its also not yet running and also kinda blurs the distinction between subway and train, running at subway frequency, on electric power and in subway tunnels, but being train sized.
Sort of. The signal system itself is a light tweaking of the ATO that's already there, but the really big gain is that it's now going to be all-fiber cabling and all- solid-state backplane other than the hodgepodge of old copper, newer fiber, and painfully vulnerable relays like the ones that got trashed in the Red Line wreck. If they want to migrate to CBTC signaling or something else ambitious they've now got the bandwidth, server rooms, and vulnerability mitigation to do it. If you've got the transmission capability, then CBTC is mostly a systems integration and software project than something which introduces much new hardware into the mix.I suspect it's unions that made that happen.

They look good, but still have the old-fashioned style to them
Depends on what you mean by self-driving:I suspect it's unions that made that happen.

So how did they come up with these red and orange cars. Did they design both basically from scratch to the requirements we laid out, and clearly they seem to be influenced at least by the previous designs.. although maybe due to the restraints, or did they have a baseline they started at and then modified them to fit our system? Besides our type 9 green line cars that are related to the muni metro cars in san fran, Ive never seen any subway cars that resemble ours.. anywhere else.
Not to mention, actually going somewhere. IIRC, the first phase of the HART connects the east side of Oahu and stops at Aloha Stadium, i.e. doesn't connect to the airport, downtown or Waikiki where the traffic clogging up the highway actually ends up.HART's are also autonomous. The MBTA's have the benefit of actually operating, though.

I'd like to think that with AFC 2.0 they will reassign the 2nd car "driver" to fare collection but I know with union rules it's unlikely. It would make perfect sense to have the front driver drive and control all doors and the rear ex driver focus on doing fare checks. Edinburgh trams run longer type 10-ish cars and they have a single driver plus a roving fare collector on most trains. Driver is perfectly capable of managing all the doors.
"the obsession with union rules" is simply that I have done work for MassDOT and have several friends who currently work for MassDOT and the MBTA and the reoccurring theme I hear from everyone is "well we would like to do that, but bureaucracy and obscure rules and laws"
