("Greendell" redirects here. For the unincorporated community, see Greendell, New Jersey.) Greendell Station is one of three original train stations built by the Delaware, Lackawanna & Western Railroad (DL&W) along its Lackawanna Cut-Off line in northwestern New Jersey. The station, which stood in Green Township at milepost 57.6 on the Cut-Off, began operations on December 23, 1911, one day before the line itself opened and the first revenue train arrived.
