The history of the Main Line began in 1832 with the building of the Philadelphia and Columbia Railway, which opened the area to Philadelphia and points west for the movement of people and freight. Along that line would rise the communities of Overbrook, Merion, Narberth, Wynnewood, Ardmore, Haverford, Bryn Mawr, Rosemont, Villanova, Radnor, St. Davids, Wayne, Strafford, Devon, Berwyn, Daylesford, and Paoli.
