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.

[3] The line's only major accident occurred on August 1, 1907, when passenger car #2 and freight motor #1 collided at Avery's Crossing in North Stonington.

[6] A Street Railway Journal article from April 13, 1907 reported:[1] As the line was built primarily for high speed operation, curves and grades are few in number.

This disadvantage was balanced in one way, as it enabled the company to use a great deal of rock ballast.Except for short street-running sections near the terminals in Norwich and Westerly, the line was built on a private right-of-way with relatively few grade crossings.

[4] From Franklin Square in Norwich, the tracks ran down Main Street, then turned south onto the dedicated right-of-way.

From there the line followed Route 2 closely into North Stonington, where the station was located at Main Street and Rocky Hollow Road.

At Westerly, many cars continued through on the Pawcatuck Valley Street Railway to Watch Hill or Pleasant View, and connections were available to Ashaway and Groton.

[1] The majority of the private right-of-way, totaling 21.02 miles including passing sidings, still exists and is visible on satellite maps.

In other places, including Norwich State Hospital and Pawcatuck, the right-of-way is no longer visible where fields and lawns have been plowed.

[5][9] Those sections, from Lincoln Park Road in Hallville to Mains Crossing in North Stonington, are relatively well-preserved, and old railroad spikes can occasionally be found.
