Right. ​MBTA distinguishes their lines as Commuter Rail ("Purple"),
Commuter boat (Fast Cat), Subway (4 colors red, green orange, blue), Bus
(including trackless trolley and LNG articulated) and ​Dedicated busway &
bus-lane (Silver Line) with articulated hybrid LNG/Trolley. Subway means
the 4 line interchanges in the central 4 underground subway stations, not
that it's in a tunnel or cut-and-cover trench for the entirety of the line.
All 4 have above ground stretches.  The oddly named "Mattapan High Speed
Line" (meaning it runs express between designated stops rather than tram
style streetcar) which is still running the vintage PCCs is the only
single-mode line in the system (aside from buses) - it has tram-style
trolley cars but has a light-rail style protected ROW all the way iirc,
including only run through a (single) cemetery in the country.

​The Orange Line used to be considered Elevated even though it had a subway
section, but now it's subway even though it has cut-no-cover and reused
heavy rail ROW sections. :-)​
