The Morris & Essex Lines are a group of former Delaware, Lackawanna, and Western Railroad (DL&W) railroad lines in New Jersey now owned and operated by NJ Transit. The lines include service offered on the Morristown Line and the Gladstone Branch. Prior to 2002, the former Montclair Branch, now part of the Montclair–Boonton Line, was included as well. The name refers to the Morris and Essex Railroad, which originally constructed the lines before being leased by the DL&W in 1868, and later outright acquired in 1945.
