There is also some commuter rail which is self powered, though I think
Budliners are getting rare. I used to ride these into Boston quite
frequently, but rode as recently as last Christmas. These days, sometimes
they are powered by a locomotive. I'm trying to remember if they even are
Budliners any more, they may be running coaches now, but I know I have seen
Budliner/locomotive lashups running on this line. It also used to be run by
the Boston and Maine separately from the T.

I think they've changed it now, but the Blue line in Boston used to be a
combination of third rail and overhead. I think the chageover was after it
got out of the tunnel on the way to the airport from downtown. The
changeover was quite noticeable as the lights would flash.

Yea, the T has a wide variety of equipment. They also run buses, and trolley
buses (electric buses powered by overhead wire like a trolley). Very wide
age range also. I remember when the Red line was extended to Quincy etc. and
they started operating new cars to Quincy, the old cars ran to Jamaica
Plains (if I'm remembering right - this is one of two terminii on the T that
I have never rode to, the other is the Green line terminus which goes to the
same place).
Boston also has a mishmash of subway, elevated, and light rail in the median
(I don't think they have any street trackage any more).
Most Bostonians also don't think of the Green line as being light rail since
it still operates into the subway system, but boy does it have some sharp
curves. There is a turn around loop just at the edge of Park Street station,
I think the radius is on the order of 50 feet. You hear a LOT of wheel
squealing.
The Green line used to be (and may still be) combination rapid transit and
light rail. North Station to Leachmere at least used to be rapid transit
with North Station also serving light rail (and actually serving two rapid
transit lines since the Orange line runs through North Station and
Haymarket). North Station is the terminus of the commuter rail for the north
and west of Boston, though you can now also change to rapid transit at
Porter Square.
