The study says expanding commuter rail service ― which the state currently operates between New Haven to New London ― to Westerly, R.I., and to Norwich would allow people to better access jobs and recreation. It adds that while the expansion could be possible to implement in the long term, it would require more planning, permitting and costly infrastructure upgrades. Preliminary cost estimates show the capital costs for the Shore Line East extension to Westerly, R.I., could be $243 million, while the extension to Norwich could cost $635.7 million, though costs could fluctuate by more than 30%. While the state has not decided whether to move forward, the potential expansion would call for proposed new train stations in Groton, an alternative to the existing station in Mystic, and Stonington Borough along the Northeast Corridor.
