History of the Main Line
The Philadelphia Main Line, known simply as the Main Line, is an informally delineated historical and social region of suburban Philadelphia, Pennsylvania. Lying along the former Pennsylvania Railroad’s once prestigious Main Line, it runs northwest from downtown Philadelphia parallel to Lancaster Avenue (US Route 30).
The railroad first connected the Main Line towns in the 19th century. They became home to sprawling country estates belonging to Philadelphia’s wealthiest families, and over the decades became a bastion of “old money”. Today, the Main Line includes some of the wealthiest communities in the country, including Lower Merion Township, Radnor Township, Gladwyne, and Villanova. Today, the railroad is Amtrak’s Keystone Corridor, along which SEPTA’s Paoli/Thorndale Line operates.
