The Moosup Valley State Park Trail is a rail trail located on the railbed of a former New York, New Haven and Hartford Railroad line in the New England towns of Plainfield and Sterling in Windham County, Connecticut. The line ran from 1898 until 1968. The rail line was abandoned in the late 1960s, and was designated by the state as a multi-use trail in 1987. The trail is owned and operated by the Connecticut Department of Energy and Environmental Protection. (Ref: https://en.wikipedia.org/wiki/Moosup_Valley_State_Park_Trail)
