Technically two or three of the silver line buses are also considered to be subway, too. I believe SL1, SL2, and SL3. They’re subway fare and they go underground at some point
There's a fourth, the Green Line (which actually has 4 branches, B, C, D, and E, on the south/west side of downtown Boston), but it is not shown in the article under discussion. There is a link in the article to another page on the same site that shows the Green Line.
