The Erie Lackawanna MU Cars were a fleet of electric multiple unit commuter railcars used by the Delaware, Lackawanna and Western Railroad (D&LW) and successor railroads in the state of New Jersey. The D&LW undertook electrification of its Morristown Line and related branches in 1929–1930, and purchased 141 motor cars from Pullman to operate it. These were supplemented by 141 unpowered trailers of various types which were converted from existing rolling stock. The multiple units were successful and remained in service until 1984.
