pretty good commuter rail that you can take all the way to the state border north or south (idk about west - western mass is considered to be a fictional location by many Bostonians)

We really ought to have regular commuter rail to Springfield, but in the meantime ….

• Fitchburg line goes pretty far west
• Amtrak long distance takes one east-west train a day, and like one or two north-south train past springfield
• Pioneer Valley Transportation (PVTA) has a pretty good bus system, fare free to all!
