Strafford is an unincorporated community in the southeastern part of the U.S. state of Pennsylvania, located partly in Tredyffrin Township, Chester County, and partly in Radnor Township, Delaware County. It is served by its own stop on the SEPTA Paoli/Thorndale Line regional rail train. The SEPTA station at Strafford is one of the few buildings that survives from the 1876 Centennial Exposition at Philadelphia. It is also the site of the Strafford Friends School, and Old Eagle School. It is in the Eastern Standard time zone. Elevation is 440 feet.The Philadelphia and Western Railroad once ran to Strafford but service on its main line was discontinued on March 23, 1956, while service on the former branch line continues as The Norristown High-Speed Line. The portion of the abandoned P&W line in Radnor Township, ending in Strafford, is now a "rail trail" multi-use path.
