The Main Line is an unofficial historical and socio-cultural region of suburban Philadelphia, Pennsylvania, comprising a collection of affluent towns built along the old Main Line of the Pennsylvania Railroad which ran northwest from downtown Philadelphia parallel to Lancaster Avenue (US Route 30), a road originally built in 1792 as part of the Philadelphia and Lancaster Turnpike and designated as a portion of the "Lincoln Highway" when that transcontinental highway system was established in 1913. The rail line, from which the area affectionately got its name, was central to creating the Main Line communities which in the 19th century became home to many sprawling country estates built by Philadelphia's wealthiest families. Currently Amtrak's Keystone Corridor and SEPTA's Paoli/Thorndale Line service the route from Center City Philadelphia, serving the original Main Line communities and beyond.
