My point was to convert the Braintree section of the Red Line back to heavy rail, but electrified. It would enable rapid service between Boston Quincy and Brockton and not be as expensive because it could use existing Red Line stations and right of way. The idea of a hub at Savin Hill could better be described as a way to connect Dorchester with the heavy rail service. I think it would most certainly improve service on the original Red Line
