Greendell Station is one of three stations along the Lackawanna Cutoff, which spans from Port Morris, NJ to Slateford, PA and was built by the Delaware, Lackawanna, & Western Railroad. The station opened on December 23, 1911 as Greensville, with the Lackawanna Cutoff opening the next day. In 1916 the station was renamed to Greendell. In 1938, Greendell was discontinued as a station stop. When the Erie Railroad merged with the Lackawanna Railroad in 1960, the railroad began to decline, and was brought into the Conrail merger in 1976. After this, rail service on the cutoff declined rapidly, and the Greendell station continued to deteriorate until 2014, when the Lackawanna Cut-Off Historical Committee was founded and stepped in to to help save this historic Lackawanna station. 

The goal of this project is to be able to have a museum that is able to educate and represent the rich history of the Lackawanna Cut-Off along with local history of Sussex County. The museum is planned have artifacts from the Delaware, Lackawanna & Western Railroad, along with other railroads historically significant to the area around Greendell.
