- Used rights of way in MA listed here to get a realistic sense of where trains/BRT’s could realistically go with relatively minimal eminent domain
- Used frequent bus routes listed here to get an idea of which bus routes are heavily used and could be eligible for upgrade into either BRT or full rail/trolley service
- Perused previous MBTA/MassDOT studies such as this and this
- Used this map to figure out the routes of all the buses
