The Reading electric multiple units were a fleet of electric multiple units operated by the Reading Company on its Philadelphia commuter rail lines. The majority were constructed by Bethlehem Steel in 1931–1933; American Car and Foundry delivered additional cars in 1949. Some cars, rebuilt in 1964–1965 and christened "Blueliners", remained in service with Conrail and later the SEPTA until 1990. Several have been preserved.
