An interactive exploration of Boston's subway system (opens in new tab)

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

Not that the adjoining cities of Boston, Cambridge, and Somerville have a public transit system that covers all completely (or indeed that even what falls under Boston is comprehensive to some areas with respect to the subway) but the Boston metro does have some form of transit that covers the area within the metro proper--past which it peters out aside from commuter rail--which is decent but which mostly functions as, well, commuter rail.

Boston is no denser than Tokyo, and compared to European capitals, very underserved by mass transit. The MBTA is a shitshow and it is fairly unusable as a reliable means of transportation.

Worth noting that the bicycle infrastructure in Cambridge, Somerville, and the adjoining parts of Boston has also skyrocketed in quality relative to its pre-pandemic state, it's extremely heartening to see. I don't take the T much anymore just because it's so easy to bike anywhere that I need to go. Shout out to the new path parallel to the green line extension, which makes it feasible to get from downtown to Somerville (and out to the Minuteman and 20 miles beyond!) without needing to navigate that viaduct and nightmare highway overpass east of Union.

My very anecdotal sense as someone who doesn't come into the city a lot is that rush hour traffic is worse than ever and transit is less crowded than it used to be be.

I actually did race it on foot a few weeks ago and won!
