Greendell Station was built by the Delaware, Lackawanna & Western Railroad in 1911 and was originally known as Greensville until 1916. Situated at Milepost 57.60 on the Lackawanna Cut-Off, it was one of only three stations constructed along the 28.45-mile high-speed rail line through rural Sussex County.
The station closed in the early 1940s and quickly fell into abandonment. Although passenger service continued under the Erie–Lackawanna Railroad after 1960, trains no longer stopped at Greendell. Freight traffic continued to roar past the vacant depot for several decades, and the site remained in limited use. Greendell was unique in that it continued to receive freight deliveries at the nearby Agway building until 1978—receiving the final freight shipment ever handled on the Lackawanna Cut-Off. After Conrail’s formation in 1976 and the eventual end of operations, the building deteriorated further and the tracks were ultimately removed.
With the demolition of nearby Johnsonburg Station in the early 2000s, local historians recognized the urgency of preserving what remained of the Cut-Off’s architectural heritage. In response, the Lackawanna Cutoff Historical Committee (LCHC) was formed with the mission of saving and restoring Greendell Station. Today, the LCHC is a registered 501(c)(3) nonprofit organization dedicated to returning the depot to its historic appearance and developing it into a museum interpreting railroad history and early 20th-century Sussex County agriculture.
