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 Center City Philadelphia parallel to Lancaster Avenue (U.S. 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. Today, the Main Line includes some of the wealthiest communities in the country, including Gladwyne, Villanova, Radnor, and Ardmore.
