The Groton and Stonington Street Railway was a trolley line that extended from Groton, Connecticut to Westerly, Rhode Island. The trolley line began service in 1904 and ended service in 1928.
The Groton and Stonington Street Railway known locally as the G&S began service on December 9, 1904. The trolley line started at Thames Street in Groton, passing through Poquonnock and Noank, and ending in Mystic. In 1905, the line was extended to Westerly to join the Rhode Island Line. The company was headquartered in Mystic, and the powerhouse was located in between Water Street and the west bank of the Mystic River. The powerhouse is still standing, and has been converted into apartments. A spur line was built in 1911 that extended to Old Mystic. In 1928, G&S ceased operating, and buses of the Groton-Stonington Traction Company began operating along the route.
