Darlington is an abandoned train station located at 612 Darlington Road in Chester Heights, Pennsylvania. The station was a stop on the Pennsylvania Railroad's West Chester Line. It later became a part of SEPTA's R3 West Chester line. The station, and all of those west of Elwyn, was closed in September 1986, due to deteriorating track conditions and Chester County's desire to expand facilities at Exton Station on SEPTA's Paoli/Thorndale Line.
