Transportation
The Main Line is served by numerous different modes of transportation among which are three commuter rail lines operated by SEPTA. Connecting the region directly with center city Philadelphia are the Paoli/Thorndale Line which shares the former Pennsylvania Railroad four track Keystone Corridor grade with Amtrak, and the Manayunk/Norristown Line which operates over the former Reading Railroad Norristown grade. The light rail Norristown High Speed Line runs over the Philadelphia and Western Railroad line between 69th terminal in Upper Darby to Norristown. Amtrak's intercity Keystone Service (New York to Harrisburg) and Pennsylvanian (New York to Pittsburgh) also serve the region with stops at the jointly operated Amtrak/SEPTA stations at Ardmore and Paoli.
The main thoroughfare through the Main Line is U.S. Route 30 which follows Lancaster Avenue (formerly the Philadelphia and Lancaster Turnpike) running east to west and serving as the backbone of the region by connecting a large majority of its towns and municipalities. Other highways serving the area are the Schuylkill Expressway (I-76) which connects it to Philadelphia, and the "Blue Route" (I-476) which runs north to south connecting the region with the Northeast Extension and the Pennsylvania Turnpike to the north, and to Philadelphia International Airport and I-95 to the south.
