The Norwich and Westerly Railway was an interurban trolley system that operated in Southeastern Connecticut during the early part of the 20th century. It operated a 21-mile line through rural territory in Norwich, Preston, Ledyard, North Stonington, and Pawcatuck, Connecticut to Westerly, Rhode Island between 1906 and 1922. For most of its length, the route paralleled what is now Connecticut Route 2.
