The Shore Line Electric Railway was a trolley line along the southern coastline of Connecticut, running between New Haven and Old Saybrook with additional branches to Chester and Stony Creek. Unlike most trolley lines in New England, the Shore Line Electric was a true interurban, running large railway-style cars largely on a private right-of-way rather than on public streets. Though its main line was in operation for only 15 nonconsecutive years, the Shore Line Electric briefly acquired a substantial network of trolley lines stretching across eastern Connecticut, including the Norwich and Westerly Railway, the Groton and Stonington Street Railway, and several lines of the Connecticut Company. Most of the trolley line no longer is extant, however, the Shore Line Electric Railway Power House still stands along the mouth of the Connecticut River in Old Saybrook.(read more...)
