Main Line

- The principal line of a railway (1841), it also has the meaning "affluent area of residence" (1930s), originally that of Philadelphia, from the "main line" of the Pennsylvania Railroad, which added local stops to a string of backwater towns west of the city in late 19th century that helped turn them into fashionable suburbs.
