Unless I am mistaken isnt the only confirmed rail service 4 stops a day from MBTA? I dont see how that would link southern RI. If we had frequent rail service between Attleboro and say New London that could help. I myself refuse to go to Logon because its so conveluted, I can imagin people in CT and Souther RI taking commuter rail to Green to fly and moreso could link the souther part of the state to Providence. But the first question still stands, 4 stops from MBTA will give a little boost but wont to much at all for the southern half of the state.
