i was wondering that too.

maybe it's because the redline takes an hour to get from alewife to braintree, and it only takes 38 minutes to get from Forest Hills to oak Grove. it's a long ride, so i assume a lot of homeless people especially now in the winter are riding it.

maybe they like the vibe of constant danger of the ancient trains giving out, power going back on and off, and the beautiful sounds. feeling like a 1970s horror movie.
